Reaching a concentration of PO4 above 2.4 ppm with Seachem's flourish is a PIMA. I would like to add more, better phosphate - stop GSA outbreaks. Maybe 2.4 ppm is Ok; I don't know. :confused: Would a PO4 concentration of 10 ppm be a problem?

Dosing Info.
Kelp!?

10 ppm of PO4 probably won't harm the tank occupants, but it is way more than the plants need. Increased PO4 dosage to try to head off GSA isn't a bad idea, in my opinion, but it doesn't take that much PO4 to be effective.

They seam to drink it in quick. Ok, your right. How about 5 ppm and I can work on it when I get back with more plants.
