High iron content in my city water

[road_warrior]

Thanks for the great info. It makes sense the dissolved iron can't be filtered.

I have an Intex 14' x 48" pool, Intex SWGC, and an Intex Sand filter if that makes any difference for my choices.

I did get the 6-way test kit from Walmart and I'm still trying to lower my alkalinity. Took the plunge today after my pH minus ran out and picked up the muriatic acid from Home Depot and looked like Breaking Bad in the back yard today.

I'll update my results when I have to fill again. I might have to try that CuLator.

On a related note, has anyone tried or had any luck with garden hose filters, specifically the ones designed for RVs?

Don't know about the garden hose filters, but here is the link to the CuLator.

CuLator - 1.5 ppm unit @ Amazon
CuLator - 4 ppm unit @ Amazon

You have to use HEDP + the CuLator -- HEDP, to keep it dissolved, and CuLator to remove it.

What's worked have been home-grown arrangements that filtered AND simultaneously exposed the water to air. Most likely, until your water is exposed to air, the iron is dissolved, and won't be filtered by a closed RV unit. Now, if you aerate or chlorinate BEFORE it goes through the filter, that's a different story.
