Product review (5 stars): EcoAqua
I haven't used this product as yet.  I'm waiting for the need to replace it is here.  However, I expect to have to replace it soon.  I'll come back and tell you how this product worked out for me after I've installed it.  I was very impressed with your e-mail thanking me for using your business for this need.  So far I can give this a 5 star rating and hope not to change my mind after installing and using it for a while.
