I have a hammer coral and a goniopora that aren't opening. This has been going on for about two weeks. The only real change to the tank is that I added some Koralia powerheads. Could the increased flow/new flow patterns be the cause?
My parameters are fairly stable at:
Ammonia and Nitrite at 0
Ph 8.4
Ca 300
Kh 7.4
Phosphate 0
Nitrate was up a little at 10. My tank has never tested 0 it is usually at 5
I use Salifert kits. the only dosing I do is B-Ionic. I use RO/DI water that I test with a TDS meter. Reading is 002
I also have a grounding probe so I really don't think it is stray voltage.
Both of the corals are about 2 yrs old. The hammer coral has grown from 4 heads to 12. The goniopora hasn't done as well but until just recently always had big old "tentacles" sticking out.
Any suggestions?
