How do you change your water ?

[Quagmire]

I just let my corals get a tan for 5 or 10 minutes during low tide

If I'm siphoning out from the display, I have some Xenia that's out of water for a bit, doesn't seem to effect it.

High and dry seems to work with my corals.

I'd only worry if I had a sponge that was near the top.

The only coral that i have that doesn't like spending time sticking out of the water is my birdsnest and then it's only the tips that suffer

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.

I have a pre-sump that holds about 30 gallons, with a by pass .
To do a water change I open the by pass , open the drain at the bottom of the pre-sump , once emptied, close the drain, refill via ro/di water on a kent float valve, once full, add salt, mixing pump, heater and let mix for 24 hours, test, and close by-pass and I'm done!
Takes about 25 hours with NO effort

Hey Mike, where were you while I was trying to sell it ?

Anyhow we did keep it, for our RO/DI and salt mixing. Never did figure out how to go beyond that, but if you want to have a look at it for design, feel free.
