samala, the red fuzzy algae is, the best way I can describe it is fuzzy. Looks like big fluffy fuzz balls. I'll post some pics as soon as I get the chance. No I am not suplementing the tank with anything. yes I have been rinsing my mysis prior to feeding, but I do realize that there are lots of broken pieces of shrimp ( heads and tails) that don't get eaten and float away never to be seen again. I don't know if maybe this is the probem. JennyL, Ihave cb erectus. MY perams are..... ammonia=0, ph=8.2, nitrite=0, nitrate=o, phosphates=0. I do 10 percent water changes once per week. I have a 45 gallon tank, I change 5 gallons weekly. I have a wet/dry filter and 45 pounds of lr. 60 pounds of ls.
Thanks so much for your imput, I really appreciate it
