Ok so I just bought a canister filter and a skimmer for my new 125 gallon tank. I am starting completely over and trying to go as slow as I can. Is a ro/di that important should I get one is what I'm getting at. Are the ones on eBay any good? Also my canister filter is a marineland multistage canister filter c-160 and my skimmer is a coralife super skimmer needle wheel protein skimmer 125 gallon are these good items??
