Gday all, So in my little invert tank I am having problems with condensation. In my last community tank the glass lids sat about 5mm below the tank top, so the condensation that accumulated on the bottom of the lids ran back in to the tank. Now for the RCS/Ramshorn tank I have is a cheap all-in-one kit with the light, filter and heater built into the lid. The problem is that the lid sits above the top of the tank, so some of the condensation runs down and down the back of the tank. I have to keep a towel there and depending on the weather, sometimes after a few days the towel is damp and there is significant loss from the tank. It is only a small tank so it only takes a few litres (less than a gallon) to be noticeable. I have tried having the temp up, and having the temp down. The tank needs a high water level for the filter to run properly, so I can't work around that. I will have to upgrade to a full glass tank soon (once these shrimplets mature hopefully). Any ideas to help with condensation until then? Thanks all!
