I was just looking at phosphate test kits online. The cheapest one is by Seachem (75 tests for 9.99 + S&H). The discription states "kit measures inorganic Phosphate down to 0.1 mg/l" (for FW and SW).

Would that be what I need to check the phosphates in my planted tank? Are all phosphates inorganic? It's been too long since I took chemistry in high school!!

Thanks!

Big Al's Online has Hagens phosphate kits for $7.79. And their shipping prices are pretty reasonable even though they are in Canada.

I used to use Salifert PO4 Test kits and like them...

I LOVE Seachem's PO4 Kit and the fact that you can do up to 6 comparative tests (simultaneously). They have a solution premade that you can use to test your readings too!!!

Thanks,
Steve

"Inorganic phosphate or orthophosphate is the soluble form. It is readily available and quickly absorbed by plants. Organic phosphate refers to phosphate that is part of a cell structure or organically bound in other ways. Organic phosphate must be broken down by bacteria in order to become soluble orthophosphate.
