Just curious as to how many folks here use some kind if Spa frog or Clear water cartridge every time you change water. Is it a necessary part of the puzzle to clean healthy spa water?
Another question. I just changed water 6 weeks ago, pump went out so had to drain the tub for repair up and running again. Water was tested & necessary chemicals were added to make the water right. Can I still use the frog that I had in there or do I need t buy a new one? I use Bromine.
The reason for these questions in I find these spa frogs to be expensive. Yet if they are a necessary part to keeping the water right I will continue to buy them. But if unnecessary....
