I tried the Bio-sphere. It works. After two weeks, the Nitrate fell drastically. By the 4th week, Nitrate is zero. Without water changes! There is a slight cloudiness at the start and if you stir your filter media (with the bio-sphere), there will be cloudiness but then again, all tanks have the same effect. So it works for me. Amazing!

My red fire shrimps molt 2-3 times a month but the small skunk shrimps molt once a month (to be fair they are so small that they might have molted and I missed it). So i suspect it is fairly normal.

Dear All, Did some research as promised. Thanks to all your subliminal (hahaha) suggestions, I realized the limitations of my little tank is temperature. (Not to mention the size.) As long as it hovers around 30 degree, I cant do much. Even with the aircon on as it is a work environment, the water is above the safety range and therefore I can only keep a FOWLR (assuming I get the abbreviation correct) tank. So.. drumrolls... what kind of chiller? My tank actual water volume is a mere 8.43 UK gallon or 38.35 liters and that includes the Tunze 2 filters and skimmers. Which means the actual volume is around 36 liters. This is what I found out. 1) The running cost of a thermoelectric device (running at 100w) is HIGHER than a chiller but chiller is more expensive. 2) JBJ Artica is quieter than the China brands but there are exceptions like Hailea 28a 3) My e-bill will kill me running nonstop at 100w. So if I switch to a chiller at 150w, what would be the bill (rough estimate)? 4) My partners keep telling me this - buy cheap buy twice. So is there a sweet spot in this selection of chiller? What are no no brands? I dont mind the PC fan noise but a buzzsaw sound will affect my work and the fengshui :-) 5) Just buy second hand? Then I can have the corals, anemone and all that stuff you lucky guys have hehe. Look forward to your advice. And yes, I have read most of the links and I really dont want to ask the same questions repeatedly. But it seems to me as a newbie most hobbyists complain about getting a noisy chiller plus a host of bad thermometer problems. Harry

Thanks for all the great advice and thank you Jackiee :-)

Will do some research there. Super thanks!

Thanks for the comment. I dont think so. The weather is hitting 35-36 outside. And the tank is hovering 29 to 30.5 with the thermoelectric device on. Of course, I dream of corals and anemone and start salivating at the LFS tanks.. but that means a proper chiller, feeding the corals, more additives and my business partners think I am not working anymore hehe. Then again, I started the fun project with the simple specs - the lowest cost 1 ft nano aquarium possible with little maintenance and only two fishes... am I wrong!

I am new to saltwater aquarium. This is placed in the office. I have many people to thank to make this possible as I am clueless - Atmos, Eric, Henry and Jackie and all the advice I got from this forum. The fish only iTank has just completed the nitrogen cycle and the max is I will add two more fishes and it is done. Everything is done s-l-o-w-l-y and I follow the instructions given by the gurus (almost like an IPO advisory panel haha). I call it iTank because it is black and white and very Mac-like, especially the LED lights. The only thing that marred the look is the newly added white 3/8 inch water tubing for the cooling device. I am trying to source for black PVC 3/8 inch tubing so that the background is totally black. Having a saltwater aquarium is one of my bucket list and now looking at the tank is like mental therapy. Look forward to everyone's advice and comment. (If I misspost, apologies.)
