I think you woulds have a great mix for a 20 long. If your problem is keeping the PH at a higher PH balance Check your substrate to include Aragonite and ad either rock chips to larger pieces of rock that will raise the PH naturally. In order to regulate this mix I would take readings before adding any rock that would raise the PH and then again 24 hours after adding a few rocks at a time until the PH is where you want it to be. This would also insure that any fish in the tank could adjust to the rise.
