Need help with diy 2 part. Also has anyone had success with this?

I didn't want to name any company names in case it is against Canreef's policy.

You would be best to use Reef Crest Part a, b and c. The amounts are already calculated out into the correct ratios.

Manage your alkalinity (keep it stable) and your magnesium levels.

The calcium levels will take care of themselves as long as you add equal parts of each (part A and B).
