I have been having problems with my water from the house and i am looking for some type of filter to attach to a garden hose that will clean the water. The water doesnt have a problem with nitrates or chlorine, it is something that wont show up in any of the test i have done. We are surrounded by farm fields and a swamp is about a mile down the road. I have been using a pur 3 stage faucet filter but it is very slow and i dont believe it is doing what all i need. I have thought about reverse osmosis but that is even slower and i have a 125g and 100g tanks. i woundering if you guys have any suggestions. I have also been priming the water.
