Skimmer for a 75G SPS tank

[Rakie]

I got my ultra low range p04 test kit today.

I got 68 ppb, which is 0.21 ppm. I don't remember if this is supposed to be .1 or 0.01. Do you remember?

Thank you!

Hey again buddy! Most people like .01 - .03, with the majority preferring a po4 of .03

It sounds like it's much more under control than in your other thread I had just read through. So you're already making good progress
