Hmm. A lil low on calcium and magnesium, but nothing that would harm your tank. I don't really think it would be your rowa. The only way to really tell is by testing your phosphates. Did you test before you put your reactor online? If that is one of your concerns I personally don't think it would hurt to turn it off temporally until things start to look better. Or like you said even take half of it out.

Could be too much rowa. Shocking corals possibly. If too high of phosphates and then you change rowa and suck out phosphates too fast. It can lead to a cyano spike for sure. Cyano will thrive and stretch for food. But will die off once phos under control. But it will take over. New light also can cause it

Phos always tested for 0 before and after but I knew it was there. When I added my rowa I did see a a lot of cyano on my sand. When corals started to go south I changed my rows and added more than I did previously. Dam chemicals!

if your test kit was telling you "0" its lying. and if it actually is "0" then thats probably one reason things arnt doing to well. sps needs small amounts of phosphates to grow and do well

I'm guessing the rowa has cleaned your water a lot faster then your coral can handle. Adding more made it worse I almost bleached my entire tank 6 months back with to much rowa to fast I was lucky and caught it before anything was damaged.

Sps need very very little phos. Like minimal. But if phos are 0, still shouldn't affect corals that much
.like 0.01-0.03 are perfect

get a low range phos test kit. Hanna checker

K I just took out more than half of my rowa. Gonna feed fish and corals double to help my sps not die. I think my zoas r done. Too much algae on it n still haven't opened

Ok so here's my corrective actions I'm going to take in the next few months to try n save my tank. Slowly remove more rowa from my reactor till I only have about half an inch. Replace my blue/white led fixture with 2 full spectrum LED fixtures in about 2-3 weeks when my tank heals a bit. About a month or so after that I'll take out half of my live rock in 1 go and put in half of my newly cycled live rock. Wait another 2-3 weeks and replace the rest of the rocks. Do u guys think this will work?

Why remove rowa slowly? Just take half out and call it good.
