GFO and macro algea

[knickle22]

I am running a phosban reactor in my sump and i am wondering if i can keep mangroves or cheato? or well the gfo just starve the macro algea.
I dont have a problem with PO4 or NO3 thanks to the phosban but just want some macro algea to get more pods.
anybody here try to run both with failure or success?

tagging along. That's a very good question. I'm currently running GFO and Cheato but didn't think if the GFO would starve the Cheato.

Both are fine, nitrates are what keeps cheato and other macros alive IMO, gfo does nothing for nitrates. I run gfo and I have several types of maco and mangroves. My phosphate is nil and I target my nitrate for 10ppm

[reefwars]

Nitrates in small amounts are great for corals phosphate is to hard to target so 0 is the goal.if you can't target nitrates go for zero.macro doesn't grow well in ulns systems

I run gfo and chaeto and the chaeto grows fine. Phosphates zero and nitrates just above 1. It grows so well that I usually throw away a soccer ball sizes lump every few months.

I know it is time to replace my GFO when my cheato starts to grow quickly so it certainly affects how well it grows.
