Hi, I have read quite a lot about RO water recently. But I've been lost in between and I just don't know what to do anymore. Should I buy RO unit and start using RO water with my tanks - cut it with tap water and add The Aquascaper complete plant food which I already use or just carry on doing what I've been doing for past couple of years which is just tap water with sachem prime and The Aquascaper plant food. I just add that I would like to keep some Amano and Red Cherry Shrimp in near future along with fishes I already have - neon tetras and harlequin rasboras. I'm preparing to do new scape just after Christmas and I want the best possible start. Please advise.
