Ok so here's my problem, My moderately planted tank is about 20ish litres (about 5 gal) with 6 danios and some shrimp and snails. The plants need the light, but the lights in my hood (decided the one it came with was ok for now, tricky to replace) is heating my tank. I have to keep turning the lights off so that the temperature doesn't keep going up. I've not let it get above 30 degrees C (about 80 F from memory) but I'm worried about my fishies and whether or not my plants are getting the required light them turned off for an hour every four hours. The plants still get 12hrs lighting each day (timer system). Any tips on lowering the temperature of my tank?
