I'm going to purchase a RO/DI unit, but in my smaller house in florida i don't really have room for storage of RO/DI water, the LFS guy which i believe most of what he says. He says that if i store my premade water in my garage that the higher temps would affect the quality of water, but isn't RO/DI water Pure? also i know i would have to cool the water before adding it to my tank too.. i also saw a write-up that had 2 wraping paper bins piped together thats 20gals which could fit next to my tank, but whats there stability?? i have one but it holds wrapping paper lol.
