Ihave some xmas moss in my 55 gal, and im always washing it b/c over a short time(about 12 hours) it goes from green to light brown, im either thinking its the lack of good filtration or the clouds of dirt from the aquasoil, now i know im not supposed to move the aquasoil around b/c the cloudiness but then how would i possibly do a pwc with vacuum? how can i get my moss to stay green and spread? this is also happening to my bolbitis and i cant afford to lose it.
