water filter
[2007]
[Aajonus]
Now, in my hot tub that I have, that I built. I got a 300-pound Hayward sand filter, which is big enough to take care of a swimming pool, but I didn't want to clean and change the sand every year in my hot tub. And I don't put any chemicals in it, so I have all this algae that grows on the concrete walls that I had built in this hot tub.
So, I like that algae. Gets nice and thick and hairy, but the water stays crystal clear because of the sand filter. Cleans every bit of everything out of it. So, it cleans and filters very well, but it allows the algae to grow and it's an excellent filter. It'll pull out almost anything.
