My GBTA has done it's second split in a few weeks and the newest splits seem to be bundled up into little marshmellow shaped cubes. I am nervous. I have never had them shrink down like this before. I am wondering if my new lighting is causing the water to be a bit too hot for them. It keps the tank around 85 degrees during the day. HMMM... I need to run either more flow with it breaking at the top of the water to release heat or run external fans tthat will hit the waters top. Does anyone know what will cool a tank better? I really do not want to add a chiller.

Thanks.
