Going to start NOPOX, a couple questions.

[1Clown]

Am I supposed to remove my phosphate media, carbon and silicate removing media? Or can any or some of these be used in conjunction with NOPOX? thanks.

Anyone?

I run nopox with carbon and GFO. no issues.

I would not remove the phosphate media unless phosphate is, or becomes, undetectable.

My preference is to remove the GFO until you see where you are at with nitrate reduction. You need both nitrate and phosphate for carbon dosing to work. If either one is limiting, the other won't drop. So I would remove the GFO until you see your nitrate and phosphate numbers drop from the NOPOX. If nitrates drop and you are now left with excess phosphates, you can add back the GFO.

Note that you need to measure N's and P's when carbon dosing and adjust your dose accordingly.
