Blocking Fish from Skimmer


For some inexplicable reason, after 10 years, I had 4 different fish decide to go into my skimmers. Two of these ultimately resulted in deaths.

Of the major Skimmer manufacturers Atlantic Watergardens offers a product to keep fish out of the skimmer called the Gatekeeper

I came up with a little simpler do-it-yourself solution using some left-over shelving from a prior project. The coated finish should not affect the fish and it seems the perfect size to let debris through but keep out my prized koi.

Just cut to the size desired and as you can tell from the video, just hook it over the skimmer and the lid will hold it in place. Be sure to sand the sharp edges to protect the liner from puncture. Rubber caps would probably be a good idea too.

  • I just wanted to share with you my post on my facebook wall…

    I really want to give a “High Five” to the folks at ThePondOutlet.com ~ I had been searching online for some type of cover for the tube that drains our pond overflow. It’s not very attractive either. Anyway, I found this site and emailed them about my problem. Richard Ross responded with this blog. It’s awesome, and now it’s my plan 🙂
    Thanks so much!

    Hi ,
    Thanks for your help with the pond skimmer protector for wayward fish. I have a fish pond net that’s torn-any suggestions on how to get replacement netting rather than having to buy a whole new telescoping pole with a net?

    Where can I purchase the gate to keep my fish out of my skimmer. Thanks,

  • Any hardware store or Home Depot where they sell Do-It-Youself shelving
