kalwalser help for high ph

[Randy Holmes-Farley]

Hello Randy, ecotech versa single dosing pump came to my country and I bought it, my tank is 160 liters, how much should I enter in 24 hours by drip method, there is a daily consumption of 0.5 dkh. I meet this need with AFR. My highest pH level in the reactor connected to the protein skimmer is 8.0. target pH 8.3 to 8.5

If you meet alk consumption by AFR (or any other method), then IMO, there's no room left to dose additional alk (say, by hydroxide) if you do not want alk to rise.

It is true that demand for alk rises as pH rises, yso you may be able to add some and not see too much of an alk rise.

You could replace the AFR entirely with a DIY hydroxide two part.
