i have a problem with my 60 gallon salt water tank. I have a CPR protien skimmer and a XP4 Rena filter. The tank is abut 3 weeks old and has sand in it. I clean the filter is always clean. About 3 days after i setup my tank the water was crystal clear. It was clear for the next 2 weeks until i bought some stuff called "Right now Bacteria" (here is the link to this crap http://www.erbio.com/?p=right-now-bacteria ) that the fish store sold me and told me i needed if i was gonna add fish in for the 1st time. (i DO NOT recommend anyone ever pour this crap into their tank) As soon as i poured this stuff into the tank the tank, it clouded the water for over a week and i cant seem to un-cloud it. Its like a white cloud. I go to other local fish stores and they say the other guy conned me and i didnt need that "right now bacteria". Ive tried everything from new carbon filter to some liquid stuff that said it would remove the cloud, and nothing seems to work, i really dont want to change the water again. i have about 6 damsels living in the water for the past week and they seem to be alive and well even in the cloud. Any idea guys on what could remove the cloud??
