softies not opening
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? |

First of all both corals you mention are considered LPS, Large Polyp Stoney corals. And neither of them appreciates high flow if you want them to fully expand.
So yeah the increased flow is probably the issue.

Your KH and calcium are low, too.

These are calcium dependent coral and like medium flow. Plus they may not recieving enough food with added flow.Maybe feed more or turn off during feeding. Also with such low calcium you may want to increase amount or how often or both of the water change scedule. Heres a Coral care site that may help.GL
