problem with the chemistry

iloveswfish · May 23, 2015

i was on vacation and my dtr was taking care of my tank, when i got home i noticed that some of my zoa's and my mushroom was not opening, and the mushroom lootks like it it dying. i first checked the salinity and it is 1.032 which i know is way to high.... i think the way to fix it will be to take water out and put ro water in. can you tell me after i get it down will the zoa start to open again?

That may solve the issue, or it may not. I always run a full test on params when I notice something wrong, but I would definitely start on dropping the salinity. Some corals are sensitive to swings in salinity so try to bring it down over the course of a few days. HTH

YEa, once you stabilize the water levels again, all should go back to what it was. Those kinds of corals are pretty tough to kill, so I think your in good shape.

I don't know how anyone can tell if the salinity is the only issue or if it is something else, but be sure to drop it slowly.

I'd replace 2-3% of the water volume each day. At 3% daily, you'll be back to 35 ppt (sg = 1.0264) in about 6 days.
