Mineral additive for Neos?
I have a couple different shrimp tanks going that are doing well in spite of my tap water (8.2pH, 3gH, 20kH), but I've decided I want another one (orange rilis are calling my name!) and I'm pretty sure I'm going with RO this time around. I got some great suggestions a while back for getting my gH up a little without making kH worse, but I decided if I'm going to alter the water, it'll be just as easy to go with straight RO and adjust it vs. fooling with the tap.
That said, I've never dealt with anything but tap water before, but I know that straight RO has to be altered. What do y'all recommend using to get the parameters of RO water to the levels that neos are happy at? There will be otos in the tank, and once the shrimp are established, it may also be used as a grow out for guppy fry (just mentioning in case the presence of fish in the tank makes a difference).
