Does anyone know if this is red Coraline or red carpet dinos? Should I leave it? It didn't come off by blowing at it with a turkey bastet but it came off fairly easily. I put it on a paper towel and was able to smear it easily. My tank was set up January 1st if that matters at all. It's slowly spreading across the rocks, but there's none in the sand.

Lenny, my lawnmower blenny trying to get my attention while I'm working. He's so silly.

Can anyone help me figure out why my tank is so cloudy? Did a 15% water change yesterday hoping it would clear, but it's the same. We have a lot of hair algae (got a lawnmower blenny). We took the front rocks out yesterday and cleaned them (just with a toothbrush to get some of the algae off) in the water we took out.

Tank is 2.5 months old, has 3 fish and a bunch of CUC. I was adding Purple Up for a few weeks every 3 days or so and that was making it cloudy, but haven't added any in almost 2 weeks because of the constant cloudiness.

Please be kind, I'm still learning. My parameters are below and have been steady. We used Dr Tim's method for startup and have had 0 Nitrites and 0 Ammonia since mid-January.
