now that was some reading material. Ordered a bottle of the commercial stuff on amazon, on its way.
I have used a different diluted product dripped into "niagara falls" area of the sump overnight before the socks. This stuff rocks, just dont drip too much/too fast and drop too much PO4 per treatment and you'll be perfectly fine.
For those just finding this thread, Amazon has the commercial (most concentrated) version for sale.
