a friend want to buy a second hand tank. but it isn't that clean any more. with a good brush and water you can clean most of it. but the problem are the kit borders/connections. on it you find some Algae. always fun :silent: you can't brush it hard cause then you will destroy the kit and resulting into leaks. not good how to clean the kit from algae without destroying it? and getting a nice result?
any tips?
