That is a fairly high alk
level and will definately cause stress in LPS
corals. The higher the alk
gets, the less polyp extension you are inclined to see.
Please post the parameters of your saltmix (alk
) after mixing for Â½ a day. You will need to do several water changes over the next few days to get the alk
back down to a reasonable level but we need to be sure that is not part of the issue.
Please also post any/all
chemical additives you are using and frequencey/dosage used?
I'm pretty sure once you get the chemistry back down closer to NSW
, you'll start seeing some improvements.
