Im buying a 125 gallon but it comes with one filter that filters about 70 gallons. Im not going to use that but was wondering what whtat would be best for my money. Something simple since I only have so much to spend. I was thinking an undergravel filter since oscars are going in and maybe a couple emperor 400 or a canister. Any advice would be helpful. There is going to be a large load on it since there will be (2) 4 in oscars 3 inch dempsey and a 3inch jag.
cuz cichlids are messy messy messy
