Hello, haven't been here in a while but thought I would drop by with some questions. So here's the story, I'm buying a 300g galvanized water trough and using it for monster fish. I will still be inserting it into a fitting with insulation and everything so don't worry about that. My only question is... How can I efficiently heat and filter it on a very low budget but still keep the fish happy and healthy? I was thinking heating the whole room but that just makes another project of insulating walls lol. So can anyone help? I'm new to this type of thing, I've been keeping fish for about 9 years now in tanks but never went monster until recently. Any help would be greatly appreciated - Matt PS I need to heat because I live in upstate NY and it gets cold in winter.
