firthy13 Posted November 10, 2011 Share Posted November 10, 2011 hey guys,i have had this tank running for about 2-3 year. i have always had really good water quality. very clear. i have always fed nls also.i run 2 2217's and an internal filter full of woolin the last 2 months water quality has really took a turn for the worse. i have been getting, what i call floaties on the surface of the water. the only thing put in to the water is food and it has never done it before. the fish wont eat it, so i dont believe its left over food. even though i did start a new bucket of nls around the time it started. i did notice is wasnt the same colour as the previous bucket. more brown rather then a browny red colour. other from that nothing else has changed it my maintenance routine. what do you guys think i could be?

kasm Posted November 10, 2011 Share Posted November 10, 2011 Did you clean your filter(s) recently? What is your frequent water change? What is your stock level?I think as fishes become more mature, system may become overloaded, you may need to do a bigger water change. Link to comment Share on other sites More sharing options...
mattrox Posted November 10, 2011 Share Posted November 10, 2011 My theory is that dissolved organic compounds cause this. I'd be trying a very large water change, followed by activated carbon run for a week. It is then taken out and another big water change is done. This should bring DOC's right down to zero.The other thing it might be is a result of the natural oils from the food's ingerdients. You mention it was a different bucket. If the oils oxidise and break down the residue is 'soapy' causing the appearence you see on the surface of the water. This would only occur if there is a build up. Following the above will clear up the the situation. I doubt the food will have had this happen as a new bucket would be sealed.Either scenario requires a build up of resides, either from fish waste or uneaten food. Stuff building up in canisters is one cause, over feeding, over stocking.... etc. Link to comment Share on other sites More sharing options...
rowie Posted November 10, 2011 Share Posted November 10, 2011 How are you mate I get the same thing in a tank that i keep near a window But the floaries as you call them that i get are a form of algae from to much sun and not enough surface movementEasy to fix a big water change and an internal filter near the surface should keep it under controlCheers rowie Link to comment Share on other sites More sharing options...
firthy13 Posted November 11, 2011 Author Share Posted November 11, 2011 Thanks for the replies, that helps. I did recently move the tank under a window and the algie has increases slightly. Ill try a few larger water changes and keeping the blinds closed and see if that fixes the issue. Link to comment Share on other sites More sharing options...
rowie Posted November 11, 2011 Share Posted November 11, 2011 If its near a window its gathering on top because of a lack of movement on the surfacePut your internal filter closer to the surface and it should stop gatheringCheers rowie Link to comment Share on other sites More sharing options...

Nodalizer Posted November 14, 2011 Share Posted November 14, 2011 If your new be careful with carbon.A week means a week. After time the carbon will leech nasty stuff and make things worse. Link to comment Share on other sites More sharing options...
