Been fighting hair algae. Was getting ahead on it then had to go to work for over 3 weeks. Got back and looked like it was before all the work I had done. My cuc is small. snails and crabs don't last long for some reason. Nitrates had gotten high at 80. but since I put the LR rubble, cheato and a reactor with chemipure, the nitrates are down to 30-40. a sea hare was suggested and i'm considering one. Just don't want it to starve if it clears up. Right now it would have plenty to eat though. Any thoughts would be appreciated.
