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
