I've had aquariums since I was a kid but by no means an expert. I currently have 3 freshwater tanks. 2- 20
gal and 1- 10
gal. I've just purchased a 55
gal and have been gathering info on best practices. From my understanding if you can successfully maintain small tanks then large ones should be no problem but again I am no expert and welcome any advice you may have. I purchased a canister filter, my first one, and I'm not sure what the best combination of media is. It has 3 levels and came with white filter pads. I would also like to turn one of my 20
gal tanks into a saltwater aquarium but have absolutely no experience with saltwater so any advice would be greatly appreciated.
