Thanks again and btw I did read the long thread in the other topic area about this. Seems like it dies nothing lol. The pool guy today told me that it acts like a "brita" filter and makes the water absolutely pure as it passes through the housing. He even told me it takes metal out of the water. LOL.

That is just plain wrong. I would talk to the pool guy's boss after downloading the info off the the Nature2 website that tells it puts metals into the water so you can show him! That guy needs to be fired! If he is the owner I would run and not walk to get a different pool guy that knows what he is doing!
