Thanks for all the input! Really appreciated.
I’ve been running this tank since September last year and my plants seem to be happy, especially since I started using Easy green fertilizer.
I’ll have to test my water before the softener which is easy as we have an outlet in the crawlspace. I believe the iron might be a problem for me as well though.
Another thing I’ve been recommended is using the water from our refrigerator which has a filter in it. Anyone tried that? That’s not quite RO water but extra filtered, still through the softener.
