Tezza Posted March 9, 2006 Report Share Posted March 9, 2006 My large goldfish, are at the top of the tank, doing what looks like gasping for air. I just cleaned it out yesterday thinking Dirty water was the problem, yet they are still doing it. Tank measures 160 cm diametor. 120 Deep. Old concrete water tank. WAter still slightly cloudy but can see bottom. there is around 16 very large fish in this tank. Advice Please!! Quote Link to comment Share on other sites More sharing options...
Tanksman Posted March 9, 2006 Report Share Posted March 9, 2006 Have you tested or had the water tested? What temperature is the water? Is there any exposed steel or metal sticking out of the concrete? Is your water supply town water or ??? If it's town water have you used a dechlorinator?

Alan Posted March 9, 2006 Report Share Posted March 9, 2006 That many fish and raw water, it is sure to be non-cycled and ammonia will wipe them out. You'll need to do water changes IMHO. Alan 104 Quote Link to comment Share on other sites More sharing options...
antwan Posted March 9, 2006 Report Share Posted March 9, 2006 They could be gasping for oxygen, do you have any type of aeration going into the tank? If not, does the surface of the water get stirred at all as to get some O2 dissolved into it? Quote Link to comment Share on other sites More sharing options...
Tezza Posted March 9, 2006 Author Report Share Posted March 9, 2006 the water is fresh from the tank (which we drink). I have aerated it for three to four hours a day, as it a long distance from the power source. Would flushing the entire tank again help? Or is constant aeration nessasery?

antwan Posted March 9, 2006 Report Share Posted March 9, 2006 Constant aeration would be a lot better, perhaps you could stick some plants in there, that would certainly be a lot easier, and your fish would appreciate them too, maybe even enough for them to breed in.

Tanksman Posted March 9, 2006 Report Share Posted March 9, 2006 Just because you can drink it does not mean your water is safe for fish. However it sounds as though they have been in there for a week or so? It's a fair volume of water 2400 litres by my calc. However they are big fish. As said above it is likely to be ammonia build up. They really are going to need a filter so that this can be eliminated by the nitrogen cycle. In the meantime you are going to need daily water changes of 50 percent IMHO. EDIT And if you stop feeding them til you get it sorted it will help. Quote Link to comment Share on other sites More sharing options...
Tezza Posted March 9, 2006 Author Report Share Posted March 9, 2006 Thanks for your input, May i ask what IMHO means? Quote Link to comment Share on other sites More sharing options...
antwan Posted March 9, 2006 Report Share Posted March 9, 2006 in my honest opinion Quote Link to comment Share on other sites More sharing options...
Aquagold Posted March 9, 2006 Report Share Posted March 9, 2006 once the algae gets going you will have plenty of O2 but the water from the tank will need to settle. pH may be swinging taking lime from the tank.... Check water parameters am and pm and see whats happening. Quote Link to comment Share on other sites More sharing options...
Alan Posted March 9, 2006 Report Share Posted March 9, 2006 The trough is an old one aqua, so the lime should have leeched out by now. Alan 104 Quote Link to comment Share on other sites More sharing options...
