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 it! 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 regrets!

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.
