Have you clean up the chiller front and back portion? It could be the filter at the front is dirty or the heat exchange fins at the back is dirty. You can vacuum both area to see whether if its helps.

Yup.. you lucky man...

lol... Lazy to start new thread. Hope all is well Omar.

Thanks, reserved for spkentchai.

Lol, no la. I only remember when I was cleaning my cupboard last night and I saw the tub with the "pilot" details and date on a post-it note. Sian...

Hi bro, Past couple of days is hot like crazy thus its maybe because your salient temperature is high thus takes longer. If this is not the problem, you may want to: Check that the chiller is well ventilated Check the fins are clean and not covered with dust Feel the air coming out from the back of your coil, if its is warm = OK, if it is not so warm = time to call your chiller tech Hope that helps.

Kena aeroplane..... and have forgotten about it until last night... lol Have last tub for sale, self collect Punggol Central.

Ice Probe works on the Peltier effect. The Peltier effect is named after Jean Charles Peltier (1785-1845) who first observed it in 1834 however it does not have much practical usage until the dissimilar metal devises are replaced with semi-conductors. How this work on the Ice Probe is the Peltier effect sucks the heat to one end (Fish Tank), the conductivity of the metal tries to draw the heat back toward the cool end (Heat Sink). Sometimes a fan is attached to the heat sink to assist in dissipating the heat of the fish tank. Thermoelectric cooling is often used when we need a solid state devise without moving parts in a small package. It is widely used in small refrigerators in hotel rooms and also small wine cellars. Thermoelectric cooling is not very efficient (10% efficiency ) compared to normal refrigeration (40-60% efficiency). Also, many have found that they are not as efficient to cool a fish tank especially in a tropical climate such as Singapore. This is because our fish tanks are not insulated compared to a fridge or cellar and therefore, these coolers will have to be on overdrive to keep the temperature we desire. With our room average temperature of 28 degrees, it is difficult to keep the fish tank at 26 degrees taking into considerations of heat generated from pumps and lights. If you desire to keep your tank at below 28 degrees, you will fair better with a good chiller. You can always get a brand new China chiller at a affordable price or look out for 2nd hand well proved chiller such as Teco or Artica. Hope that helps.

Hi bro, It is very subjective. Some reefers: will test almost everything will use their eyes, experience to gauge the increase or lacking in certain elements depend solely their equipment simply leave it to nature to take its cause Herewith are some common elements that we look out for, it depends whether it prefer to trust their eyes, experience, equipment, nature or to use test kits: Ammonia - Needed during cycling Nitrite - Needed during cycling and FOWLR Nitrate - Needed by LPS and SPS pH - Needed by systems that employ De-nitrator and Calcium Reactors Silicate - Needed when you experience Diatom bloom Calcium - Needed by LPS and SPS Carbonate - Needed by LPS and SPS Phosphate - Needed by LPS and SPS Magnesium - Needed by LPS and SPS I used to have chlorine test kit as well, I used these when I have aiptasia problems and finally resorted to bleach my entire tank and pipe-works. I need to chlorine test kits to let me know when my tank will be safe to re-start. Hope that helps.

A recent post in Pasar Malam re-kindled my interest in Sulpur Denitrator. Professor Guy Martin from Ecole Nationale Supérieure de Rennes was believed to be the first person to applied the sulphur denitrification into freshwater treatment for public. In 1991, Marc Langouet, who is a student of Prof. Martin decides to test this method on seawater. After 3 years of testing without apparent toxicity, Marc proposed the idea to Michel Hignette - Curator of MAAO Paris. And the rest, as most will say, "Its History". I have a Korallin C1502 Calcium Reactor which I have converted to Sulphur Denitrator 2 years ago but disconnected after I kept Nitrate in check. However, as I added more fishes Nitrate began creeping up to about 4-5ppm. As I currently do not run any other Nitrate Reactor or Bio-Pellets Reactor, I decided to do a simple experiment before I install into my main tank. In Sulphur De-nitrifications, Thiobacillus denitrificans and Thiomicrospira denitrificans, are able to use reduced sulfur compounds as electron donors and respire on nitrate in the absence of oxygen. What it means in layman terms is that the bacteria will strip Oxygen from Nitrate and by-product will be Nitrogen. According to Randy Holmes-Farley, herewith is the equation - 2 H2O + 5 S + 6 NO3- → 3 N2 + 5 SO42- + 4 H+. Korallin Sulphur Denitrator, this reactor has be disconnected from my main tank 2 years ago, as you can see the media (Sulphur & Carbonate) has turn black in certain parts. Water container A and B. Both container will contains similar amount of water from my current tank. DD Test kit, in my opinion this is by far one of the best I have used. It allows you to both test for NO3 and NNO3. Nitrate Test on Container A = +-4ppm Nitrate Test on Container B = +-4ppm Container A will be connected to the Sulphur De-nitrator while Container B will be Control. Container A and B in position Both container will remain in the semi-darken sump area of my tank for 1 week. No additional intervention. .... Day 7 .... Water from Container A of the left and water from Container B on the right. Notice water from A is brownish due to dirty Reactor. This picture is taken before adding reagent. Side by side comparison of water from A and B. A with Sulphur de-nitrification read 0 while B is 0.50 on the low range test of DD test kit. Pros: Short kick-in time compared to carbon based de-nitrator No hassle of constant feeding of ethanol Efficient even for Nitrate below 5ppm No need for additional feed pump (Applicable for Korallin and similar designed reactors) Cons: Prolonged used may lower pH FAQ extracted from - http://reefkeeping.c...1/diy/index.php How long does the media last? About 3 years according to the manufacturer. Is it hard to adjust? Not harder than a calcium reactor. The only daily adjustment you have to make is to degass the system from the top valve. About 5 seconds. What is the effluent's pH? The pH out of the effluent in my unit reads 7.5 I smell rotten eggs out of the effluent? The bacteria are not getting enough food (nitrates). At this point the unit needs higher flow or some of the media needs to be removed. Can I store the media for later use? Yes, wash the media thoroughly with RO/DI water and store in a sealed container for future use. Do I have to use aragonite on top of the sulfur media? No, but it helps to buffer the pH a bit and it buffers your tank at the same time. Don’t count on this to replace your calcium supplement anytime soon. Do I still need to do those dreadful water changes? Yes, water changes help dilute some of the more toxic compounds in your water and replace all the lost and absorbed trace elements in your aquarium. Do I need a recirculation pump? Yes, all figures are based on this. Recirculating reactors are much more efficient and are better at preventing media channeling. It also prevents air pockets within the media that kills the anaerobic bacteria which we're trying to culture. Can I use a bigger recirculation pump? Yes, you will have to throttle it back with a valve to prevent the media from fluidizing and becoming mush in there. Does Hydrogen Sulfide accumulate when using one of these denitrators? In most cases, no harmful concentrations of H2S will occur. If you are overly concerned about this there are two way to combat it: (1) Maximize aeration. A high oxygen level drives hydrogen sulfide oxidation, and high aeration will drive some off as volatile H2S gas. (2) Pass the water over iron oxide/hydroxide (GFO) to convert hydrogen sulfide to elemental sulfur. What are the cons of running a sulfur reactor? Your Alkalinity levels will drop faster than without using a sulfur reactor. It is imperative that you keep an eye on this parameter. So will I be adding this reactor to my reef tank? Yes for the time being as I am experiencing higher nitrate than I normally used to. However, I will dis-connect and reconfigure into a Calcium Reactor once I am done and have the CR run permanently when I am tired on dosing 2 parts solution plus magnesium. Happy Reefing.

Thanks for sharing Mike.

Interested in sea fan... Let me know....

Closed as requested. Was interested in your sea fan but did not PM you as I do not want the other 2.

Many years back, there will reefers who used glass beads 1mm diameter. They did this so as to ensure that they do not accidentally introduce pest into the tank. But this idea was not well receives as glass beads look un-natural plus - 1) Not porous to support higher beneficial bacteria colony, 2) Does not buffer and support pH unlike coral sand. I don't see any advantages in using Sudo as I believe they are pre-washed sands harvested for fresh water usage. These sands could be silicate/quartz based rather than carbonate base than we prefer. You can get corals sands easily and economically, If cleanliness is as issue and you do not want to wash the sands yourself. You could get those commercially packaged Live-sands - these tends to be cleaner (depending on brands) and they also claimed to have beneficial bacteria to assist in the start-up of your tank. http://www.madpetz.com.sg/index.php?main_page=index&cPath=1_133 http://freshnmarine.com.sg/estore/index.php?cPath=435_93 Hope that helps.

One of the best dissolving salt I have used.

No worries mate! Up, Good price for these little tank cleaners.

***Duplicated Topics Merged into 1.

Ditto.. Don't expect to be spoon fed, I don't think any taxpayers will agree to Gov freely giving out grants / assistances without efforts from the receiving party.

I have used API 5-1 and I find them quite accurate for FOWLR. However, do do that the accuracy will drop if the strips are exposed to humidity, thus only remove 1 strip and cap back immediately. If you are looking for the more accurate titration test kits, try DD, Salifert, Elos or Tropic Marin. I personally prefer DD and Elos.

Sealife and LCK201.

It is a must for any Government to have a controllable supplies of necessities to help cope hostile situations or natural calamity. Water is 1 that our Government is very focus on - NEWater, Desalination plants, Waterways. Fuel, in the form of Crude and Natural Gas are not naturally available in Singapore but through our refineries, we managed to acquire them from different sources and also keep healthy stock pile. Food, basic food such as eggs are greatly supported by our Government. Through technology transfers and collaborations, AVA is also working closely with Riau Islands on Vegetables and Food Fishes culturing so that these will be supplied back to Singapore on a regular basis. Seletar area was ear-marked for residential and aerospace industrial development and it is our Government's visions to move Agriculture to CCK and Sungei Tengah area. In 2007, SLA releases 4 sites in Sungei Tengah on a 20 years lease. Personally, I find there are adequate plans and considerations by the Government on a macro level but I feel that these plans lack depth as in it does not address the long term livelihood of the floating farmers. I used to have some projects with Chew's Eggs and I am aware of the close relationship between our Government and the farmers, I hope that these closed relationship can be further accorded to the rest of the farmers.

For water, 1 drop is approximately 17 to 25ml depending on many external factors such as viscosity, density, temperature and humidity. However, as a general rule of thumb, most agrees with The Marine Aquarium Reference (1992), in the appendix it states 20 large drops or 25 small drops approximately equals to 1ml. For potent medications such as Copper is its best to get as accurate as possible if not, to be slightly under dosage just to be safe. Hope that helps.

If you only need 7 to 8 meters, you can speak with the LFS mentioned above, they should be able to assist.

+GF+ pipes are not really expensive, it is their valves that are expensive. Most reefers feels that they valves are of better quality and chances of leakage and breakage is lower. Another reasons why we use +GF+ is because it is DIN standard therefore it fit better with German equipment that comes in DIN standard as well. However, do note that +GF+ is reluctant to sell direct to consumers and further to that their Singapore Office don't carry the pipes that we normally uses, thus you sometime may have to wait for special orders. Personally, I will still get +GF+ but instead of from them direct, I get from Reef Systems. As for pipes and elbows, you can get VDL from Madpetz or Reef Depot which are also DIN standards. I find getting from retailers/LFS more convenient than stockist. However, if you intends to buy in larger quantities and don't mind the distance and sometimes lack of service, you may try getting from stockist direct. Another alternative stockist is Glynwed which carries FIP valves and pipings, however do note that they are located in Changi. Besides the above, some reefers also get their PVC from Hai Cheong, from my limited knowledge they carry mostly the ANSI Schedule 40s. Hope that helps....

With regards to the grants, I believe it is the same everywhere, recipients will need to justify in order to get $$$ and I totally agree with it. And I truly believes that the farms will benefit by working hand in hand with AVA. What I find lacking is the supports from entities down the chain. Take for example our local produced movies/TV programs, they are willingly accepted by the media owners and the public. These can only be achieve if the Restaurant Owners, Public are aware of these farms. Yesterday our local media reported that Kranji Countryside Association pitching with our Government to set up a Farmers Market at the old Neo Tiew Market, I feel that this is an example of farmers being pro-active in getting into the black. And I believe our floating farmers should do so as well.
