stephikinsfish Posted June 17, 2009 Report Share Posted June 17, 2009 I'm not sure what's going on with my angels. In the baby tank I have about 40+ babies and there is a layer of bubbles on the surface. However I have the same thing in my big angel tank. Both tanks are 200litre and seem to be fine. Ph levels are fine etc. Any ideas what the bubbles are from? Is it dangerous? Quote Link to comment Share on other sites More sharing options...
BikBok Posted June 17, 2009 Report Share Posted June 17, 2009 surface scum? this used to happen with my old goldfish bowl until I realised that surface scum will cause bubbles due to a thin film on the surface. I increased the water changes and added an air bubbler while I looked for a bigger home for them. Quote Link to comment Share on other sites More sharing options...
Dixon1990 Posted June 17, 2009 Report Share Posted June 17, 2009 Yeah, if you are already doing enough waterchages just add a airstone Quote Link to comment Share on other sites More sharing options...
