i use peat and my waters slightly "murky" id say the tannins are mostly from all the wood i have in there though, but who knows since i have lots of wood as well as the peat. i put it in the empty media cartridge of my filter.
i dont suggest using pH up or down to mess with pH. this can make your pH unstable and be all over the place which can kill fish.
as for RO i know a LFS ( not a chain store like petco ) had it for i want to say 49c/gallon and saltwater was $1/gallon WITH your own containers to fill. im not 100% on that price as i never bought it, i just purchased a RO/DI unit w/ a TDS instead. i figured $1/gallon with 100+ gallon system would have easily cost more long term then just buying the unit upfront. just something to consider. with a smaller tank, and 50 cents a gallon for just the RO water it may not be to bad. i would search your area for some good LFS ( local fish stores, not chain stores ) and see what they have to offer price wise as im sure every place does it different.
