Currently, I have flexible vinyl tubing off of the overflow and into the Sump. My problem is that I have moved my Cheato into the first section of the sump since it is larger.... I have a very powerful LED light that grows the Cheato.... Amazingly!!! .... but because the vinyl tubing is see through there is all kinds of nasty looking algae growing in the tubes. Picture of drain and Tubing I would love to hard plumb... but I don't know if I really know how to do all of that. So I was thinking of just getting some flexible pvc pipe and replacing the vinyl.... Any thoughts? Also, how do I know what size to get.... How do I know what size will fit the (is it bulkhead?) the hole coming out of the overflow drain? Would love any input or help! Thanks!Here is a video of the full sump setup. Video of sump set up
