So a little while back I performed a mod on my skimmer's collection cup to add a drain so that I could drain the skimmate into an external bottle. Well, someone brought up a good point, what if the outlet of the skimmer blocks? This would cause the skimmer to overflow into the skimmate bottle and pretty much empty the contents of the sump and probably tank onto the floor. I had a hard time imagining the outlet of the skimmer blocking but hey, I am not one to tempt fate! Murphy is a strange yet powerful force.
Anyway, here is my solution to that..
What we have here is essentially an old hang on filter all gutted and plugged up to act as the skimmate collection cup. If it should overflow for whatever reason, it will just dump its contents back into the sump. Yes, disgusting but at least it will keep water inside the tank!
