Switching to RO

So, i've got liquid concrete flowing from the tap at school and want to either balance it out with RO or completely fill the entire tank with RO water. I have a few questions on this line.
1) I currently am planning on dosing EI, do i need a GH booster to go along with that to supplement the RO?
2) I think i'm gonna do a GBR tank, so would it be better to go all RO, 50/50, or maybe something in between? I typically can't keep the pH below 8 and the gh and kh are supposedly both very high (i don't actually have test kits for these... i know... it's bad).
3) I have some texas holey rock in my tank currently. I'm thinking i may yank it, but if it were to be counterproductive to the RO, i think it would definitely get yanked. Is is counterproductive?

Any parameters can be posted (or if you're really resourceful, you can find them through my sig )

If it was me I'd at least try a 50/50 blend with GH Booster ether way at least you won't have to worry about adding buffers.

I lived in Fishers for three years. The water spots on drinking glasses was annoying. I would get a gh kh test kit and see what happens with the 50/50 mix.

Texas Holey Rock is a calcium carbonate or calcium/magnesium carbonate rock, which is holey because water gradually dissolves it, making the water harder. If you use it I suggest being sure to keep up with weekly 50% water changes to limit the effect on hardness. I doubt that the increase in hardness will be excessive if you do those water changes.

Yeah, i like that idea. I think that i'll pick up a test kit next time i'm buying. I would guess that the 50/50 would make the gh and kh more reasonable (and hopefully bring the pH back on the scale )

Yeah, that stuff is definitely still dissolving, i tried to move it and it cracked into 5 pieces. It can find a new home in my scaping refuse bucket.

Are you using your own RO unit or are you buying RO water from a grocery store like Meiers or something? I used to see those RO water machines in the grocery stores out there and always wondered how much calcium and magnesium was reduced by them. I only had Goldfish when I was out there and they liked the water. Have you thought about keeping African Cichlids? The water would probably be idea for them. Vals and Hornwort would probably like the water as well.

I have my own RO unit that i bought online... I'm actually not a huge fan of African Cichlids, but i know that a lot of people around here love 'em.

Have you looked at the dwarf cichlids you might like them.
