NO3:PO4-X

[R.J]

Hi guys,

I have GFO and biopellet reactor in my sump, is that ok if I use NO3O4-X also?

Yes
Carbon dosing should be fine as long as you have a skimmer.

I have been for a year or more. I have it on a doser channel.

Be careful. Very easy to bottom out your phosphates and bring on a mess of problems.

As mentioned, I'd watch your phosphate and nitrate levels. Biopellets are more a less the same thing....a carbon source to grow bacteria, which is then removed by your skimmer. Also note that you need both phosphate and nitrates for any type of carbon dosing. If one or the other is in limited supply, carbon dosing will not work.

It’s safer to add than subtract these parameters- I’d look into creating an ultra low nutrient system, and dose the required amount of + NO3/4 I’d required
Use the NO3/4 X as a failsafe (slowly bringing the parameters down) if you see a nutrient spike outside of your desired range.
