i have some LR being stored in a tub till i'm ready to use it, the water level is slowly evaporating, how do i top this up? plain RO water or Plain Ro with additives as I have heard just plain RO on its own is not good. or should i bite the bullet and get 40 gallons into my tank and store it in there as i'm thinking with the lid on the tank i will get less evaporation......... many thanks, Kevin
