Looking for a GOOD concentrated PH UP, ( 50 gallon batches multiple times a week)

I was using dk420 (discontinued on amazon) i think that is what it was called.
it was kinda pricey for the size, but a half tablespoon would PH a 50 gallon to 6.3.

Anyways prefer amazon, and i dont mind mixing two or three dry products together as well, I know there are some good dry recipes to make your concentrate for pennies. i just cant find them anymore.

Thanks I'll check it out.

2.5grams brings my ph down from 6.8 to 5.7 (using the pH down of coarse)

Get some potassium carbonate. Otherwise read here for more info.
