For those that use 100% RO with success, that's probably not DI also, right? The small amount of TDS that gets through presumably has enough minerals to keep your plants healthy. My tap TDS is ~340
, and my post RO is 7. What's your post RO TDS, if you've measured it?
I use RO plus Triple DI--(Zero! ppm). Here's a Pic:
The RO water comes out of the membrane into the horizontal DI (which really isn't worth a flip--so I added the Dual DI) into the Dual DI on the floor. No I don't Need
Lab quality water--But I Want
I want the Zero TDS starting point. Silly? Maybe!
I have been using 100% RODI Zero TDS water for the last couple of months or so and have absolutely No
My Specs: Unaltered pH: 6.8, Kh1, Gh 2.25-2.5 I don't reconstitue anything. I add P, K, Micros, Black Water and Fish Food.
