I need a whole house filter(s) for three problems.
1. Rotten egg smell. I live on Virginia's eastern shore and this is a common problem, supposedly from decaying organic matter.
2. Light brown stains in sinks and toilets.
3. Water hardness is 120, based on one of Filtersfast water test kits. The water test kit did not show any other problem.
I have 2 1/2 baths, plus use water to keep a 24' above ground pool topped off, and for normal watering of flowers and a small garden. There are just two of us living in the house.
