Increase pH without increasing alkalinity?

I think chasing ph is dangerous, I've had so many customers come in after crashing theirs tank trying to chase ph. I would leave it alone unless it goes dangerously low. my new tank has been swinging low to 7.7 but nothing is stressed, I just leave it.

So should I just leave it even if there's a .5 change throughout 24 hours? The lowest would be around 7.55-7.6

I don't wanna do anything drastic and that's why I'm asking first. I'll try to aerate the water in a separate container to check if it is a CO2 problem, if not I will just leave it.

I was told to leave it alone too.....

do you see any problem with livestock?? mine goes from 8.1 to 7.5 daily with no problem.

Well I have gotten 3 Acropora Secale and they all get brown with little polyp extension, and one died. Not sure if pH is the problem though... all other SPS look fine, so I thought maybe the a. secale could be more sensitive to pH than the others.

what exactly is your filtration

what exactly is your filtration

Deltec MCE600 and biopellets. Could biopellets have something to do with the low pH? I have been running them for about 6 months

there's your answer the pellets have bi product of co2 which will crash ph. the outlet needs to be as close as possible to skimmer so it can aerate the water from pellet reactor before entering tank.

Should've said I had biopellets before, my bad. The outlet is pretty close to the skimmers intake already but I was thinking on getting a PVC tee to have the skimmer intake and reactor outlet connected to it. I just procrastinated on that mod. I would go to home depot to get the stuff but is closed already. Will try it tomorrow and update results.

Thanks

cool glad we figured it out!!
