I have a cpr overflow box and I was wondering if I should drain it and clean it on a regular basis.
Sniperhank said:I clean mine. If I don't, I end up getting all kinds of nasty build up and algae growth inside it. I have a toothbrush and a pipe cleaner for cleaning my tank, they work wonders if you don't want to take it apart to clean. And all the garbage you scrape off goes right into the sump/skimmer.
