i have brown crud all over my tank. i know that it was because i was no useing RO water. about how long after you start useing RO water does it take for the brown stuff to go away? i have it on my sand, and on my rocks. is there anything that i can do to help this along? could it be that i do not have enough circulation? also, i only have two large snails, not sure what kind they are, i think they were called zebra turbos. i have smaller ones, but my blue leggs killed them all. i had tons of empty shells for them, but they did not get along. Would emerald crabs help to clean off the rock?
