PH is jumping !!!!!! Please advise!!!!

Hello EVERYONE!!!!! I have a little problem: within a day, the pH fluctuates, in the morning it's 7.8, and in the afternoon and evening it's 8.2 or even 8.0!!!! I used BUFF Red Sea, but there was no noticeable stabilization. Has anyone solved this problem using "folk" methods???? Also, the aquariums are clean and fresh, and the cooler runs around the clock, using RED SEA salt!!! Could this be causing the death of 5 anemones? Has anyone used baking soda, and what side effects are there??? Thank you all!!!!!!!!!!

Hello Slava, this is a common occurrence in small volumes, I wouldn't pay much attention to it if I were you. As for baking soda, I wouldn't recommend playing with it. You won't be able to maintain the pH; you'll just raise the carbonate level and deplete calcium. Everything needs to be added in strictly calculated doses. PS anemones don't die from this, good luck.

Your pH fluctuations are within acceptable limits; the only thing I don't quite like is that the morning pH is 7.8, which is the lower threshold for seawater. It would be better if the morning pH were 8.0, then by the evening it would likely rise to 8.4, but this is quite a normal phenomenon. There are practically no aquariums where the pH does not change throughout the day. You are probably using a colorimetric test; if so, before doing anything, you should check the readings with another test and another person, as errors in measurement using the colorimetric method are quite possible.

Try adding calcium hydroxide, lime water, in the evening, as the pH always drops at night. By adding a small amount, it won't drop below 7.8.
