  1. Thank you for the pump and your generosity. It will be used for a school's eco pond - vertical garden project. I hope I will put it to good use.

  3. Calcium shall be adjusted by using red sea foundation a, kh/ph with foundation b and mg with foundation c. As for filtration, mechanical, chemical and biological filtration are deployed. Mechanical : coarse sponge, deltec mce600 hob skimmer, seachem clarity as flocculating agent on a need-to-use basis. Chemical : seachem matrix carbon, seachem purigen, rowaphos. (dosed in excess of approximately 2x) Biological : mixture of eheim bio-rings, live rocks, seachem matrix. Bacteria additives (tlf npx, seachem stability, brightwell microbacter, prodibio bacteria, microbe-lift special blend) will be added to provide for the initial seeding for the bacterial population. As one might have heard, a hungry man is an angry man. And an angry man is an unproductive man, as we saw from the recent strike. Hence, we do our best to ensure our bacterial population are well fed for maximum productivity. We will be dosing reef carbon from brightwell and carbon from prodibio as carbon sources. A tiny dose of vinegar shall be added in for that variety and different "taste" that all gourmets carves for (the use of different types of carbon sources may minimise the occurrence of mono-colony of bacterial population).
  4. Even though the tank's "shelf life" is approximately 4 days, we believe in setting up a tank that is sustainable throughout an aquarist's journey into reef keeping. Hence, we spare no effort in the setting up of the filtration and water parameters. Mr eheim strongly believed that it is not fish that one is keeping, rather, it is water that one is really keeping. An excellent filtration system with uncompromising water quality is paramount in reef keeping. No effort shall be spared even for a competition tank lasting only 4 days. Due to technical restrictions, it is unfeasible to produce 20+ gallons of ro/di water for the mixing of salt mix. Hence, we have decided to use nsw provided by the sponsor. That does not mean we are compromising in the quality of the water. pH and temperature will be measured using a 2 points calibrated (7.01 and 10.01) matrin instruments pH meter with temperature display (ATC). Salinity will be measured using a 2 points calibrated (ro/di water at 18 Mohms/cm and saltwater at sg 1.026, 53mS/cm) refractometer from trans instruments (ATC). Mg/ca/kh will be measured with d-d test kits while no3 and po4 will be measured with salifert test kit. For the water to pass quality assurance test, it must have the following parameters : No3 = 0 ppm Salinity = 33 ppt Kh = 12.1;4.3 dKH;meq/l Ca = 440 mg/l Mg = 1310 mg/l Po4 = < 0.03 ppm
  5. Salt mix don't freeze well using household freezer. Try filling soft drink bottles with 85% water, freeze it and throw bottle into sump
  6. that's a brillant idea. I hope I won't be senile enough to forget to even put on the band, haha. I also try to do that too, somehow, I keep forgetting a lot of things. age is catching up too fast. most corals are fine. snails are fine too. all fishes and shrimps died though. i don't think it's the lack of nutrient export, it is most probably due to the lack of adequate oxygenation. thanks for your offer. nano tank crashes are usually swift. fast to kill, fast to fix, haha. it seems everything is fine now, I did not even do any water change after crashing. should be due to lack of oxygenation. my tank is cube shaped, less surface area than rectangular shape. And I am at the higher end of ideal temperature range.
  7. Forgotten to turn back on the skimmer for more than 8 hours. Tank crashed, =( That's why I need an aquarium controller or a skimmer with feed mode. Should have gotten a more noisy skimmer. My bad, old people, lousy memory.
  8. thanks bro inwear. thanks for your interests. The reef-safe-"ness" depends on your definition. The reason for my sales is due to it being too active and that it is chewing off my shrimps. It does not bother other fishes except for its activeness, it is estimated that it swims a complete round the tank at approximately 2-5 times per minute. I have LPS and zoas. It does not bother them except trying to peck at food which the corals seems to be undamaged by the pecking. If you are keeping bristleworms, I would advise caution with this fish as I used to see quite a lot of bristleworms. The fish started to drag out some of the bristleworms and within 3 days of its introduction, I have not seen a bristleworm ever since. It may eat pods too. Shrimps do no go well with it, however, I only see it pecking at the top shell of the snails and the snails has no reaction to it. It recognizes the location where you place food and it will react very excitedly to your hand when your hand is near the top of the tank. I have tried taking over more than 50 photos, and I only managed to get this single usable shot. https://docs.google....c1N5VmhvTC1nUEk (download for high res) From what some web site said, it is supposedly a rare import. Warning: it can eat around 10-20 1mm pellets a meal, two meals daily.
  9. selling above. 1-2". feeding pellets well. extremely active. $10
  10. Not really weird. Not many people using due to cost and singapore businesses tend to lean to the safe side, most will not take any risk at all. Hence, most wouldn't carry to prevent being stuck with stock which eventually expires.
  11. Is the shipping costly? Yes, rd does not carry zeovit anymore
  12. Wow, where did you guys get such amazing chalices?
  13. Bro, your fart does not replicate /reproduce. Pathogens do. Let's take the sars for example. Hong Kong is larger than us. Apparently, sars cases there are more numerous than us. In epidemiology, host density, immunity and movement is much more critical than space between them. Once you are infected, it does not mean you are always conferred with immunity. If you look at many human diseases, most pathogens have the ability to transmit to other hosts while the infected host has no obvious symptom. If you noticed, quite a number of marine ecosystems comprise of reefs. Those are very densely packed in a small area, allowing very rapid spread of pathogens to susceptible hosts. The very large volume of water in the oceans may not have such a great advantage as you may have imagined. Reefers rarely keep open sea fish species, hence, releasing of infected fish may pose a problem. Fish moves. The 5 vs 50L doesn't make much difference if it is swimming actively around. Some fish does not show symptom when it is chronically infected with a low level of pathogen. Those pathogens do not have a lifespan as the population is maintained by constant death and reproduction. Some pathogens can exist as spores which can be extremely resilent. I am not talking (focused) about fish to corals. Intraspecies transmission does happen rather frequently. Pathogens reproduce and mutate very frequently. HIV, CJD, H1N1, etc. That's one of their mechanisma for species survival. They have to cross infect for a much better chance of survival, and mutation is a tool they use to achieve that and increase virulence. If there's a marine spca in singapore, i would love to help out. I don't recall spca releasing their animals back into the wild. Name me a legitimate lab that releases their bacteria back into the wild after their research, even if they are harmless.
  14. We do not know marine pathogens extremely well. Captive fish may be partially immune to them. No symptom doesn't mean they are not a carrier. 1 recent article : Imagine you go toilet, wipe butt, never wash clean, go feed fish. Fish carries the pathogen. You release to sea. Pathogen grows and overwhelms the local population. There's quite a few articles on captive fish causing outbreaks in wild. Google them. If a wild fish can cause an outbreak in a captive tank, what makes you think the opposite can't happen? A tank may have limited space, but they have limited biomass as well. In the wild, the biomass is much larger. If the local population meets a foreign pathogen which they have no immunity to, it can spread like wildfire. For an exaggerated simulation, please proceed to the nearest cinema to get ticket for resident evil: retribution. Remember, pathogens are not like toxins.Huge volume of water has limited effects to their spread. That's what makes bio weapons much more effective than chemical weapons.
  15. Even if you caught from the sea or if it is a local species, still I do not recommend releasing. It may harbour some pathogens that is not found in our local ecosystem, possibly wiping out local population if it is extremely contagious.
  16. May not be ok for them. Corals are less likely to survive acclimatisation when they are already damaged before introduction
