I currently have 5 nassarius 5 trocus. I’ve read bad things about hermits hunting down snails so I steer away from them, even though I like em. And was told trocus have to be constantly righted or they’ll die. I have a half bag of chemi-pure in chamber 3, I use RO buddy with di. I believe having Phosphates and nitrates at zero got me into this predicament. The algae on the rocks really doesn’t bother me, gives color to bland dead rock I used and keeps my lawnmower fat. I just want that nasty cyano/dinos to go away. Maybe I’m just being over anal but makes feel like I’m doing something wrong when I see pink slime on what’s supposed to be white.I see a little cyano, diatoms and turf algae. The stuff on the rocks: brush with a Firm toothbrush or auto detail brush.
Reduce white light intensity and Check your phosphate and nitrate for elevated levels.
Add the following snails:
3 turbo
3 astrea
3 Trochus
3 Cerith
4 Nassarius
6-8 blue leg hermits.
Also add a pouch of chemipure Elite will will keep Phos and nitrates in check
Are you using RODI water or tap water from the faucet ?
Is tank at or near a window?
