How do you change your water ?

[BCOrchidGuy]

I have a 5 gallon aquarium in the garage that actually only holds 4.5 gallons of water. I fill it with 4 gallons of fresh water and add 2 cups of IO salt, I let it mix for 24ish hours. I have a 5 gallon water jug that's marked for 4.5 gallons and I siphon the water from the tank, sometimes I take some from the sump but because it's low there isn't much of a siphon created. I dump that down the toilet or out the back patio depending on if there are a lot of weeds or not. I rinse out the water jug, and fill it again with the new water from the garage, pour it in and turn on the sump again.

ps I'll add about 1 ml of the RHF Ca and Alk to my 4.5 gallons before I add it to the tank.
