I've run these before. Just place a filter in the system. Whatever else
you do is secondary. Dirt, bugs spiders and whatever don't matter if
there is a filter. If you are not running a production shop that filter
will see only a few hours a week of use and last "forever".
The simplest possible setup is a bucket or tub with a submersible filter in
the bottom of the bucket. Then the output and return lines go to the
bottom of the back and if there is a leak it leaks back into the bucket.
Then (key point) cover the pumps intake with a few wraps of "filter fluff"
and secure it with a zip tie. If you want to streak the water use
anything that is marked as SAFE for animals and pets. If it will not kill
a cat, it is safe for your pump and motor. I think $3 Vodka would work
well.
As long as you have the filter zip tied to the intake, noting gets into the
system.
The other thing I used was a floating aquarium thermometer. This lets
you know if the tank is large enough. If the temperature shoots up you
need a bigger tank.
Summry: (1) use a filter, after that no much else matters
(2) use only "pet safe" chemicals but only if you have an
actual problem that needs a solution. I keep aquarium tanks filled with
just plain water and they remain clear for many years at a time. With no
fish, any way-cheap filter will keep the water clear. An air-stone powered
filter would work and cost nothing to run 24x7. he airstone also cools the
water by turning it over.
