Alk issue

[Proteus]

Alk is dropping fairly quick but cal and mg. are stable. Alk dropped for 9 to 6 in 3 days. While ca is 490 and mg is 1530. Ph 8.2. Temp. 78

I have great growth on sps and great color. But why is alk dropping so fast while ca is not

I had the same issue before I started dosing. The other Params were stable, but alk was dropping hard. However, I didn't have very good growth at all on my sps. Now that's i dose and it's stable I have great growth, but my system still draws hard on alk.

Did you just switch test kits?

If you are not dosing, this is completely normal.

2part solutions have different concentrations of each so its not like we are adding the same amount of alk and cal when dosing equal parts.

Never let your alk get bellow 6.5dkh. The base of your SPS will STN at lower levels.

I try and keep my alk @ 7.5-8.0dkh to prevent tip burn in my ULNS.
