I am looking into mixing my own salt as my LFS store only offers TMC salt and it doesn't allow me to boost my KH or PH via the salt mix, so im thinking of moving to the red sea mix, however, I dont have a RODI unit and even if I do I would need to us it outside on a hosepipe and its winter right now, so I was just wondering how long can I store RO Water for to mix salt into in the future? I have around 4-5 25L containers, Could I fill them all up and each week mix my salt into them for my water change? Or would that cause an issue?
They would be stored in the boiler cupboard which is right next to my tank, so its dark house temperature.
