Ph

[louscal]

What is the best way to raise ph as it gets down to about 7.7-7.8 at night time. Just a little concerned

Thanks in advance

7.7-7.8 is just fine. My tank runs this all year long. Don't change a thing.

Usually a CO2 issue.

Open a window. Draw skimmer air intake from outside.

Do you test for alkalinity? If that's low, it can contribute to low pH. As stated, 7.8 isn't too worrisome.

Yes I test my alkalinity and it is usually between 7 and 8 dkh or 143.2 on api tests

I agree with above. High sevens is my normal too.

Ok so I'll just keep a close eye on it. Either way I think I'll try and run the intake for skimmer close to drag air source and see if that helps out as that may be the issue cause we run central air through the summer so probably some stagnant air in here lol

raising the alk a bit will help too..
Might want to switch to a different salt brand.. One thats a bit higher in alk.

got corals? Might be time to start dosing alk

I use tropic marin reef pro. Just starting to put stuff in I just started dosing seachem 1&2. So I'll keep an eye on it
