Hey guys, I'm new to big tanks, formerlly a 55 gal and just got my 200 gall to house my 3 RBP 1 jack demo, 2 oscars, 13" pleco, and 13" marble moray. I will be using fine sand, fake plants and alotta rock/drift wood in it and feeding live food alot, my question is this.. Currently I have 3 Marineland penguin bio-wheel filters on it at 70GPH each, what would be th best filtration to compliment them to keep my water crystal clear? Like a wet/dry or canister, and what size should it be as far as GPH and also hat brands are good to dish out money on? Thanks for the help, I'm new so Te most details/ explanation as to why would be great, also any suggestions on anything I should know would be much appreciated! Thanks guys and gals!
