I don't understand why my PH won't go over 8.0. I dose soda ash for my alk, but it won't take ph over 8.0. when I start dosing, it quickly goes up, but then hits a plateau. I dose vinegar during the day, which pulls it down to 7.8-7.9, then soda ash brings it back up to 8.9 during the night. I guess this ph range is not bad, and who knows if my probe is even correct (I checked with an api ph test, and it also showed 8, but again I don't trust it much). But mainly I am curious as to why soda ash, and connecting an outside line to my skimmer does not raise ph over 8.
But is what I am wondering is why does it not keep climbing with adding soda ash? If you look at yesterday vs today, I dosed 2X soda ash today vs yesterday, but the ph loos almost identical.
I also tried running a line outside for my protein skimmer, and let it run for 3 days, with no change to PH. I did that a few months ago, so the chart I attached does not show that time frame.
specs:
300 gallong tank
alk 7.84 (went up to 8.1 after dosing extra soda ash)
ca 430
mg 1464
PH: 7.8-8.0
