I think I have bacteria present in my well along with Iron. I am looking for a whole house filter to clean up the water to be safe for drinking. I have the red staining in the toilet (iron?) and my dogs tested positive for Giardia (bacteria?). The vet said only place they could have gotten it is from the water. If someone can recommend a home test or a reliable place to send the water for testing that is not going to break the bank it would be appreciated. Also I was looking at systems online and found this system which seems great to me but i am no expert in water quality. www.thewellguru.com What is your opinion of this system and is it worth the price tag? Thank you in advance.
