Added some chaeto to my 75g, in my homebuilt refugium sump with some LR
. There's about a softball-sized clump of it. Its a nice deep green color, its lit well, and seems to be growing over the last few days.
My nitrates have come down from above 10, to now to between 5.0 and 10, where usually every 4-5 days my nitates go from 10 to 20.
Is chaeto really capable of eliminating that much nitrate?
Should I let it grow until it fills the fuge, then start clipping it back to export it?
