I run a refugium with Cheato and GFO reactor. So it’s usually zero but when I dose reef roids I see levels of ~.12Well what is the PO4 level when you don't do anything to modify? too low, too high?
Great idea! I was leaning that way and you just confirmed it!Maybe dose Reef Roids in smaller amounts over multiple days so you don't get that spike. If you're zeroing out PO4 I would take GFO offline and use the time of the refugium light as a variable to keep PO4 where you want it.
How long can GFO sit in a reactor before solidifying? Does it matter?No worries! Keep an eye on nitrates as you go. If you zero nitrates the Chaeto won't grow and PO4 will rise. Thats when you can bring GFO online until you get nitrate/PO4 in a good balance.
How long can GFO sit in a reactor before solidifying? Does it matter?
Yeah. The smell of water that has sat in a reactor for a week is awful. Not sure how long you should let it sit though. Anyone else want to chime in on that?I don't think it'll solidify but the water in the reactor will become stagnant
