Hard water(Iron) - please help

Hello all,
I've grown a few crops before but all at different homes. Again I find myself in a new home but this time I have well water.
Running tests on my water I have found that it is hard - too much iron.
I'm planning on starting a grow within the next few months and was wondering how I could fight this outside of water softening devices for my home. Though I have not seen what effect it will have on the girls, I know it can be bad and just wanted to nip the problem in the bud.

get a ro system off ebay for $100.

Thank you very much for the quick reply.
Not only have you solved my problem for growing but also for a system for my garden =)

Seconded RO.

If iron is your only problem, however, you could probably buy some super-power neodymium magnets for cheaper and just use that to pull the iron out faster than an RO system will filter.
