What is a good liquid solution to soak my used air stones in so that all the gunk from the old roots comes off? I soaked them in soapy water and some of the gunk is still stuck on them.
Same goes for the tubbing, what is a good solution to soak all my old parts in to get rid of old nutrients/ gunk?
