To solve this whole issue, rob does not have a tank, nore does my water changes I handle everything. He carries the jugs up my stairs. And I already figured out what was up with my water thanks to a ex max reef employee and will no longer be buying there water anymore first and last time. I heat my water he just never pays attention to what I'm doing cuz he's sitting in my computer chair bit**ing to threads instead of trying to help me lol (sorry to blow up your spot babe) I use pre mixed saltwater ... Carib'seawater if u didnt catch on before, and also use rodi water to make sure my saline level stays the same 1.025ish. If u add nothing but the pre mixed salt water from those jugs you get a salt spike after a while. I'm not careless I love max reef and I trusted them to give me "RO" water. They did not. End of story. I don't want a ro system and will not be getting one because honestly I don't see it as a necessity, in fact I see that as lazy.... I go to the lfs for food... Additives... Corals... Fish... Why can't I get my water from there I'm already making atleast 1 trip a week there. No need for me to get one and mess up and flood my house with my family in it. My 56 hour work week is hectic enough without me coming home to a unexpected swimming pool which I've read about atleast 100 times on here. This wasn't my mess up, or me being careless it was on someone else's accord.
