Can someone give me the run down on RO vs Deionized? I am contemplating purchasing an RO unit from Debron Aquatics. They have a 50 gallon/day TFC for $160 or a Maxima 50/day for $230. Are these good prices? The Maxima has a deionization cart. attached, is it worth the extra $70? Thanks for any imput. I want to make my purchase within the next few days. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
