Dosing question

My pH is always low 7.3-8.1 and use a co2 scrubber plumbed outside. Having the window open does not effect.

I am mixing my first batch of 123, used premix prior. It sounds like start with half the dose from the pre-mix?

If your mixing up your own batches now and using the video I made as a guide, then yes start with half of the recommendation.

Test test test... you'll need to be vigilant for the next week or so with your testing to get things dialed in. [emoji6]
