I've got two 6000 streams that I've had running in my 180 since last september and they're starting to look pretty grungy with a lot of algae covering them. I'm just looking to find out what the best recommended method for cleaning them is. Should I take them apart and scrub them with a toothbrush in some tap water? Or should I just let them soak in a vinegar/water solution, muratic acid/water, eze-clean? Any advice would be appreciated.
