Well, my thinking is, and I'm sure someone will come along and correct me if I'm wrong, that for this application a filter is not necessary.
They don't spend all their time in there, they just get in and out when they want to cool off. They aren't eating in there, and probably aren't peeing much in there. The water is going to get dirty (with dirt) before ammonia levels or anything else rise. So, I am just going to keep the weeds out of it, and when it gets dirty, I'll change the water.
I want to leave the water in it as long as possible so I don't always have to wait for the temp to rise, that takes about a day. But, I don't think a filter is necessary.
