Wellllll ... I dunno.
The cooling tower is a one-time investment, and requires very little maintenance.
I sold a Wix Aquacheck
system to a customer which worked quite well, but I suggested my cooling tower idea to him in order to extend the life of his filters. I do know that he came up with a cooling tower design of his own, but I left the store and no longer have him as a customer. It would be interesting to find out how the two worked together.
