Brown stuff growing on cc!

[chrismilano]

Help. Im in the 3rd week of my cycle and I have orangy brown crud growing on half of my cc (i know, i know, but im keeping it and doing a fish only with 50 lbs tufa and 10 lbs of live rock)
What are the best cleaners for this stuff? How many for 70 gallons?

your tank is still cycling let it go until its done, a couple more weeks probably..I find for the brown not to much cleans that..although you should get some snails and hermits to help with other algea and detrius..the brown on the cc will go away w/ siphoning the cc during a cleaning,you will probably also get it on the glass it will just wipe away...

no sweat, i have a 55 gal fish only tank. i had the same problem. turned out to be diatoms. if everything is correct, it should disappear in a week or so. good luck!
