I do have the plastic cover for it and thought about putting it on . I don’t like the look so much and it’s not a good fit because I have a slit in it to slip it on and the fan flaps it in the breeze.A crafty gal like you shurly could come up with a plastic cover.
Ok thanks. I covered them.Roots don't like light.
That’s what I do as well but I still get algae. It must be my drip ring .i cut pieces of panda film with a hole in the center and a slit and use those to cover my WFs. no more algae on the top layer of media
