Hi there, if the fish are ok even in that very hard water the temptation would be just to use your tapwater as is , just aged. As you have got yourself an R/O filter though you might as well use it. To increase the efficiency of the filter good pressure from the water mains is important, if it not high enough you can get a booster pump. Also does your R/O filter have a back-flush to clean the membrane every few uses? It will increase the long term efficiency and durability. I would probably start mixing the r/o water with tapwater about 50/50 in the ageing bin to start and see where that gets you
