Po4 - so4

If I'm testing my phosphate with a test kit is it the PO4 that I'm testing or will the SO4 afflict it also ?

The phosphate (PO4) is completely apart from you sulfate (SO4). These variable should not affect one another.

I think 1/8 tps would give you 3ppm for every 40g. It really depends on how much phosphate your tap water has and how much you already have in the tank. I say try to keep it under 10ppm. I prefer 5ppm. Phosphate does not get used up as much as other nutrients.

I use just under 1/4 tsp three times a week in my 75 gallon. Running EI dosing. Check out the threads regarding that method, I think it's terrific. If you would also like to evaluate how much your dosing and see it graphed over long term check out this really simple website.
