Total Noob Question: Phosphate

[George]

Hanna 713 PO4 checker(I assume that's the one you have) has an accuracy of +(-)0.04ppm. So your water out of the reactor could be 0ppm or 0.05 ppm. As long as water out of the reactor has a lower PO4 level than the tank water, then your GFO is still good.

This Hanna checker is very nice and easy to use.

Thanks

I was hoping it would be more accurate than that, but at least it will tell me if my media needs changed or not.

i dont think they can make it that accurate because there has to be a difference between your reactor and your display.

if phosphates are added to your tank, which is inevitable, the reactor turns them into zero. there has to be the change over period.



ive heard of fox faces mucnhing cyano before so thats a good thing

You have to find what works and just stick to it, I have a 90gal heavy fed and 500ml BRS HC GFO changed every 3 weeks works for me, I regenerate my GFO to save money.

Hmm. I don't think ROWAphos can be regenerated. I'm going to have to investigate. It was quite costly, and that certainly affects my willingness to change it often.

[Cal_stir]

It has to be high capacity GFO to regenerate it, the reg stuff disintegrates too easily, I don't know if rowaphos can be regenerated.

I know you want phosphate to be as low as possible but what is the accepted maximum for an Lps reef
