I just completed and added my home made plexi canopy. I dumped the store bought glass cause, it just won't end well in my mad house. Within 20 minutes I had a HUGE amount of condensation. This is a given, considering I keep my house 72 and my tank 78. I also noticed the side with a filter cut out doesn't have as much. That said, should I ventilate the canopy? I can do it in such a way as to keep splashing near anything electrical to a minimum. Will this affect my lighting? Hopefully I did this right and you can see what I'm talking about.
As a side note... do I need more air in my 55 gallon? It's gonna be planted in the back, with a school of fish (live bearer) and a hand full of emerald cats. I've been looking around and it looks like a lot of people here have the whole air bubble thing going on.
