Protecting a Closed Loop Intake

[Ruth]

Heck I just use the strainer baskets on mine. I run my closed loop with a sequence hammerhead (5800gph) I have never had a fish stuck to it - a couple of snails but that's it. I think most fish can swim well enough unless they are weak because of illness or whatever. Even my 2 firefish are OK and I have seen them swim right by it. No dumb fish in my tank!!!!!!
