Thanks all, I will post all my test results when I get back home. (sorry away most of the day today).
My test kit is a API Saltwater Master Test Kit. It has Nitrate, Nitrite, Ammonia, and High Range PH. (no copper though, have to research that one).
I use RO
water all the time, changed my filters around October or so last year. It's a 6 stage system, forget the name of the brand. I am cutting my feeding down to every other day now, that is another good tip.
Again, appreciate everyone's comments. Hopefully can get back on track soon!
