Help with Alk and PH swing

[fredjr]

Hi, I need a little help with tank chemistry. My tank is for the most part stable but my PH and Alk has what I think are big swings. I use Red Sea Coral Pro salt. Here are my parameters for one week on my Red Sea Reefer 350 thats been running for almost 2 years :

Cal 404 to 392
Alk 7.22 to 6.78
PH 8.05 to 7.93
Phosphate 0.04
Mag 1350 stable
10 gal water change weekly
I dose 80 ml Alk from 7:30 pm to 6:30 am and Cal 80 ml from 7am to 7pm. My PH low point is from 10am to 12:30 noon. I was using ph buffers but I didn't think was a good idea so I stopped about a month ago. For filtration I run filter socks, skimmer, small refugium with some chaeto and BRS universal Co2 scrubber.

Those numbers actually look pretty good to me I know my tank has a bit of a swing from day-to-day I wouldn't be too concerned with it

So you don't think I should get my Alk a little higher to get more coral growth?

As long as it's around 7 it should be fine. Stability is more key than high levels there is a coral supplier on here who keeps his alk at 7 and his corals are amazing I keep mine at 8 and it floats from 7 to 8 daily

Ok cool, thanks. Maybe I'm worried about nothing.

Yeah, dont chase numbers, itll drive you crazy. Of everything is healthy and growing just keep cruising along

It is certainly fine to boost alk a bit more if you want it higher.

The pH swing and range are fine.
