In the UK we are have some weirdly hot weather at the moment for a long period of time...

My tank is overheating but here is what I'm doing to deal with it... I thought it might help a few others.

Freeze 2liter bottles with RO water, screw cap back on and figure out how many solidly frozen 2liters to drop in sump
