Tripple O Water Filtration?
 

Someone recommended one of these to put in my water tank as a filtration
system.

Has anyone used it or something similar? I'm looking to pre filter my Well
water before I put it in my storage tank. Any other recommendations? I'm
still working on the water test, though I know I have Iron, Manganese, and
hard water for starters.

Thanks,
