Been using a turf scrubber for a year or two now. Since about a month ago it has stopped growing almost altogether, and I cannot figure out why. I have a couple tiny bits of ulva intestinalles on the screen thats it. Usually that stuff grows like crazy.
Tank specs:
- 78f
- Calcium 460
- Kh 8.5
- Mg 1400
- Sg 1.026
- No3 ~20ppm
- Po4 .14ppm
My nutrients are elevated, mostly because it stopped growing. My po4 crept up to .3 ppm before I added some gfo.
The screen gets plenty of flow and I have very intense led lighting on it, think it's a 200w grow light running 18 hours on and 6 off. I don't believe these are the issue as it had been growing like a monster for quite a while under these conditions.
I'm thinking I might be limited in an element. Can't be nitrates of phosphates, and I started dosing iron (fergon) about a week ago but I haven't seen any changes.
Any ideas are appreciated. Thanks!
