This site helped me a lot over the last 2 years of my 90 gal
reef tank but what I learned is follow advice but learn yourself too ! I use 2 do a 20 percent water change weekly I was tiered of the work so I was going to sell my $5000 tank after a year my wife was yelling at me saying I told u so !! I took a trip to my lfs
and he gave me some great advice ( being I purchased 100 percent online) he said if u have no nitrates why u changing water ?? He made me buy a bio pelet reactor and a bottle of trace elements and he said try it out and keep testing and see how it goes ! Well it's been a year now plus I sold my rodi
2 and only use tap water for my auto top off and tank has never looked better fish are huge all my soft corals multiplied my sps
are huge no more cano or red algae yes I have top equipment but every 2 weeks I clean fluval pads and every month change Purgen and chemi pure and I finally love my tank 0 work !!!!!!!!! My levels are perfect no nitrates,phosphates alk
and calcium is perfect but I due add bionic every week !!!!!!
