Noticing my sand is turning red. Already tested my water for calcium, nitrate, nitrite, salinity, PH, and ammonia. They all came out fine. Temp kept between 78-80 degrees.
Also the heads of my euphillyas are falling off. Not sure what’s off with my tank. Any help would be appreciated! Still pretty new to the hobby.
