The airstone wont do any harm so you can leave it running, while the filter is still using a lot of the oxygen it will help to increase the surface aggitation so the gas exchanges at the surface are quicker.

All it says that all systems benefit greatly from water changes and that the recomended ammount of water to change is 20% fortnightly for a lightly stocked tank which should be increased with heavier stockings.arcticfox said:In reply to CFC I think you might like to read this information http/www.thetropicaltank.co.uk/wchanges.htm
Well guys, seems like the problem was solved, No need to argue. Everyone has different ways of doing things. They work for some and not for others, we all got different water, different fish, different enviroments. So if something works for someone it doesn't mean it will for another one. They are just suggestions., the description did sound like ammonia levels going way over and it could also have been a nasty disease brought up by the Angels.
out there as you can see.
