I have a 20 gallon tank. I have soem brown stuff on my sunken pirate ships sails that wont come off. The sails are a fabric. Its storebought but i have rinsed it, scrubbed it but it wont come off! Is this bad for the tank? Also on some of my fake plants they are brownness. It looks like algae but its hard to get off. Help!
