Should I wait ... or should I play with chemistry?

your alk is low for sure I would bring that up. Once the alk and CA are in balance the corals will take off

why are you using ozone?

Your Alk is fine. What is your Mg at?

good call. I was wondering if I needed to by that test kit. I have good salt (with sufficient Mg) and do water changes about every 3 weeks. further, i have Mg dosing solution but don't plan to tie it to an automatic doser like the Ca and Alk.

I recently started having some RTN and STN on some of my SPS and my readings for Mg were in the 1100 range, but I also had a low Alk (5.5dkh). As soon as I corrected these my corals recovered and really started to take off. I did weekly water changes (Reef crystals), but it was not enough to get the extra Mg boost I needed. I am switching to H20 salt to hopefully alleviate my Mg problem without having to dose.

This is why I asked about your Mg.

I'm still kinda new: what is RTN and STN?

Slow or fast tissue necrosis. Its when the flesh of the coral starts to recede. Sometimes it happens overnight and your entire coral is gone or sometimes it's a slow process over many days / weeks.

Strangely enough when i used RC on my 97 and 404 I rarely ever used any of my Mg chems. It was always at 1400 but I was never sure how lol.

Yeah, I have read about RC having MG levels anywhere from 1000 to 1450 over the last few years.

ok, thanks - alk up to what constitutes balanced?
