Do most of you use RODI units when it comes to water changes and water top offs?
I am just getting into the hobby and am getting as much info as I can.
Thank you

I use RO water. But apparently it is unnecessary on Victoria water.

DI for myself and I usually do the water 24 hours before a water change, I don't want to leave it long enough for bacteria to really start to grow, I figure if I waited a week I'd be starting the nitrogen cycle in the replacement water.

Use RO/DI water.
As soon as salt dissolves no heat no air. Changing 5% per week.
Been doing that for 9 years now. Emptying the bucket strait into the tank.
All is OK on all tanks.

I voted for 24 hours because that is the minimum I usually leave it however if I had the room I would always keep salt water mixed up and ready to use.

This is interesting and kind of goes back to a post I made a little while ago - I leave it with PH's, heater and salt for weeks at a time. So far it's served me well, and ensures if there's an emergency, I can dip right in and have premade goodness ready to rock. I've left it up to about a month and a bit when things go a little insane, and so far no issues as long as the temp and salinity match :)

Ditto, I also keep mine aerated to raise the ph.

Does it count if I mix the water and then age it until I'm ready to get off my lazy bum to do the water change?

:P

I usually let it mix for 10-24hrs. If I forget to do it saturday I'll do it sunday morning and do the water change sunday night otherwise I do it some time saturday then change water sunday. I guess instant ocean really isn't instant.

I use a purley h2o RO/DI unit.

all of the above..
