An update...... I’ve been using the PPS dosing formula for just shy f a month now. The recipe is:
K2SO4. 14.65g
KNO3. 16.3 g
KH2PO4. 1.44g

Dilute to 8 ounces (250 ml) and use 1/4 ounce daily.

For trace elements, using CSM+B 1/2T, about 10 grams) diluted to 8 ounces. First 3 weeks, had used 10 ml of this (using up previous batch of solution) and now will use only 5 ml daily going forward.

It took a couple of weeks, but I think I am starting to see algae taper off. Plant growth is good.

Continuing with weekly water changes (RO water treated with Sea Chem Equilibrium)..

I thought PO4 was a pretty big driver of algae, but maybe it was too low for good plant growth.

Will update as things unfold.
