I have a Tesino GP232A 50W 6500L/hr, 4.0m. Just brought it from overseas and found too powerful for my tank. Can be considered as brand new. It is a very silient and low power consumption.Selling at $120 fixed. Collect at Tampines. PM me or sms me at 96693543. Thanks.

I'm new to marine fish keeping. I'm intending to start a tank with the following: Fishes: 2 to 3 false percula clown / ocellaris Substrate: Fine Coral Sand Others: Live Rocks No corals / anemone Due to my freshwater keeping hobby.. I already have some of the following: 1) API Ammonia test kit 2) API Nitrite test kit 3) APT Nitrate test kit 4) Petfran PH Pen Some other solutions such as Seachem Prime and different BBs. I've bought a Dymax IQ5 (tank, led, pump) together with its protein skimmer. The shop where I went to had no idea on how to use the protein skimmer, they don't even bother to answer me and there are no instructions or anything within the box. I will be using NSW to start my tank instead of salt mix and will cycle my tank with Waterlife Bio-mature(ammonia actually) before I introduce any LS in. My Questions are: 1) How do I install the protein skimmer (for those who've used an IQ5 Protein skimmer) 2) Can any seniors here advise me on what else do I need to get for the setting up. 3) I need a hydrometer.. any good hydrometer to recommend for the IQ5 tank? 4) Any good LFS to go to for good advises into starting marine fish keeping? 5) What are the recommended medias for the IOS of IQ5? I've bought a pack of mini porous CR. Intending to use Seachem De-nitrate as one level too. Will cut the black form shorter so can't place more different type of medias. Thanks all for your attention and your help!

Deionized Water Defined Deionized water is made by exposing tap or natural spring water to electrically charged resins, which bind to the mineral ions or salts in the water, including calcium, iron, copper, sodium, bromide and chloride, and remove them. Distilled Water Defined Distilled water is also demineralized water, but the minerals are removed through distillation, which involves converting spring water to steam. Since the minerals are too heavy, they remain behind while the vapor or mist is collected as it cools and condenses to create distilled water. If distilled correctly, the water should contain only oxygen and hydrogen molecules, have a PH level of 7 and contain no other minerals, contaminants or gases. credit to: Read more: Deionized Vs.

Yes totally agree. Where do you stay. if you stay in the west. just bring over a jelly can. i provide you FOC

Just to share on this article; Enjoy!! A lot of hobbyists enjoy the colors of sps corals. Some hobbyist might hesitate about the idea keeping sps corals due to the impression that in order to grow these corals you need expensive chemicals, supplements, and even certain equipment. In actuality, you can cut down on a lot of unnecessary cost that makes growing even the rarest acropora coral affordable. With the economy that we have been through in the recent years, more and more hobbyist are looking for ways to lower the cost of keeping acros. Here are a few guidelines that can help lower the overall cost of keeping delicate acropora corals. -These guidelines are not intended to give the impression that this is going to give you maximum growth of your acros. It also is not stating that other items are not beneficial to a reef aquarium but mainly states that the marginal benefit of these items is not greater than or equal the marginal cost of these items.- 1) Lighting - Pick which ever lighting you wish to (MH, T5, or LED). As long as the lighting ha enough par, it will work out fine. I personally run 250w HQI MH lights but acros can grow fine under different lighting. 2) Flow - A common misimpression is that you have to alternating flow in order to grow sps corals. This leaves hobbyist having to buy expensive controllers and pumps, which are major fixed cost. SPS corals, especially acropora corals, survive best with turbulent flow. This type of flow can easily be accomplished with a variety of pumps that fits your budget and needs. As long as the pump does not have a stream line type of flow, it should work fine. 3) Nutrient Removal/Reduction - Ever since to evolution of the protein skimmer, hobbyist have been able to keep more delicate acropora corals in captivity. The protein skimmer should be the largest investment that you make in your system equipment budget. I cannot stress to value of a well-built protein skimmer. This does not mean that you have to buy the most expensive skimmer, just one that is adequate for your aquarium’s needs. Most hobbyists now believe that you have to run Carbon and GFO in order to be able to grow acros. However, this is not the case at all. Carbon and GFO are used to supplement the protein skimmer in order low the overall nutrient level of the reef system. A well-established system (6 months or longer) has enough beneficial bacteria in it so that as long as you keep up with your water changes, your system will do fine with keeping acros and will not get overgrown by algae. 4) Temperature, Salinity, pH - These two parameters, along with pH, are influenced due to the external environment that the system is in. -Temperature stability is a critical factor with keeping healthy sps corals but most hobbyists has also found that these corals will live in different ranges. The main thing is to keep the temperature as stable as possible, not matter what the temperature reading is. Some systems can run without a chiller but this just depends on certain factors like water volume, lighting, pumps, external temp, and others. -Salinity stability is simply achieved with an ATO system. A float valve with a cheap dosing pump works like a champ. I use a tom aquatics dosing pump and a float valve from here. -Monitoring pH is more important vs actually trying to keep you pH stable. Your pH level is going to tell you that may have over dosed alkalinity or other supplements that you might have chosen to dose. You'll find a huge benefit in monitoring pH vs testing it. Often, a large pH swing will get recognized much earlier than with a manual test reading, potentially stopping a tank crash. 5) Test Kits - It is important that you understand why you are testing the parameters that you are testing for. New Reef Aquariums need to test for Nitrates, Nitrites, Ammonia, pH, and Salinity. These systems are too new for sps corals but should do fine for most LPS corals. SPS keeps should mainly test for Calcium, Alkalinity, and monitor pH. You can buy a phosphate test kit if you want to but if you keep up with your water changes and don't run gfo, there is no real urgent need to test for phosphates. Out of all of the parameters to test for, I test alkalinity much more than others with salinity next on the list. 6) Supplements - An old saying is that if you cannot test for it, you shouldn't dose it. It is easy to get the wrong impression with all of the uneccessary supplements that are available on the market today. Calcium and alkalinity are the only supplements that you need on a regular basis. This is usually achieved by dosing kalkwrasser in sps reef aquariums. Kalkwrasser is best used in a reactor with RO/DI water but can also be added via a drip bucket or even in your ato container. Part A and Part B supplements work in place of kalkwrasser or to be used along with kalk, depending in the system needs. SPS systems do require an initial investment no matter which route you wish to take. If you follow the guidelines above, you can easily keep beautiful and colorful sps corals without wasting funds on unnecessary cost. Feel free to post comments or methods that you take in order to keep growing sps corals affordable. Hopefully this thread will allow new sps hobbyist to keep the beautiful corals without spending too much.
