New salt- lps stressed

Jordanwilsher · Feb 27, 2020

Hi, changed my salt from instant ocean to Red Sea coral pro. Did my first water change and against advise I did 10% water change of new salt. Come back from work and all most all my hammers and torches are closed right in. The lights were due to go off in the next half an hour so don’t know how much they have been out throughout the day. Did my water checks and my alk has jump from 8.5 to 10.5 in a day. The weird thing is I have 3 monti digi which are all out perfect as well as my clam. What are the chance of the surviving an alk swing and what is the best option now? Picture from a few days ago.

a 10% water change caused your alk to spike from 8.5 to 10.5 in a day using RSCP which tests about 11.8 for alk? I would retest to make sure this is a valid/reliable reading -
Important to monitor lps opening tomorrow and if you are still concerned might consider another water change with IO to reduce alk, although two alk "swings" would put a lot of stress on your corals. Hopefully, they adapt quickly and look good tomorrow am.
Good luck.
