I am building some large, flat, open tanks for water in my greenhouse for a heating/cooling system: see more details here: https://permies.com/t/108087/car-radiator-heating-greenhouse-sizing
I have a non-submersible pump which will be pulling the water out and running it through a radiator before going back into the tanks.
The water will not be super dirty, but I would like to grow a few water lilies in pots and keep a few fish to eat mosquitoes. And the tanks will be open, with plants in pots set on plants above them to save space. So some gunk will end up in the water. I need to protect my pump and more importantly the radiator.
If I drilled a bunch of one inch holes in a five gallon bucket, wrapped it tightly in landscape fabric, and put the pump intake inside of it, would that do a fairly good job of keeping unwanted objects out? How fast would it clog up? Any better ideas?
