Water changes

[john fox]

15 gallon tank ; when I do a water change can I use RO water with no salt in it I'm changing 1.5 gallons.

I would change 10% twice a month
and you can use ro water but do have to add salt to the proper salinity.

[stevem]

when topping off evaporation water just water no salt
salt dies not evaporate.

I was just in BKLYN zoo and he said I can use aged tap water adding salt of course to the correct salinity <"((><

[john fox]

I needs a cleanup crew any suggest tions

[stevem]

yes our water in ny is very low in tds
so you can get away without a ro
But you do not need to age the water just adj temp and declorinate.
then add salt
always adj temp first since this effects the salinity
