Using just RO water , non planted tank...

[bluelagoon]

Have you considered crushed coral in your filter.The right amount should keep the water from a ph crash.The BB will benefit more than a ph of 6.In the Amazon a ph of 6 is fine and dandy,but in a fish tank things just don't work the same.

I added Kent Discus Essential. pH is 6.0 to 6.5
GH and KH are slightly elevated (perfect) . Nitrite 0. Nitrate 5-8. They seem happy. Also added half dose of seachem nourish for my anubias tied to wood , on my bare bottom. I added half dose of nourish seachem because it has almost the same thing as my Kent Discus Essential. The Nourish seachem has added iron and NPK ...but I don't need alot because anubias are easy to keep .

I think you did a sensible thing, keep us updated with the progress

[Johney Blaze]

I could say my tank is now balanced...there are so many things that can go wrong if you have 0 GH and KH, soft water. Calcium and magnesium are a must for fish and bacteria, including plants...but small amounts for our Discus. Go Chargers !!!

If you have a planted tank, you might want to use Seachem Equilibrium or similar product that doesn't contain NaCl. I don't know about anubias, but my plants didn't grow well when I was using RO right to remineralize my RO water. Also, Discus Essentials isn't meant for remineralizing RO water, but as a supplement.
