IO Salt

[reefme]

Got a hard time mixing IO. Always leave white residue behind. Is anybody have a same issue or just me?

sounds like you are adding it to the water to fast and it is precipitating out. i mix in a 25 gal container 4 cups at a time and never had a problem

How long between cups? I heard people can mix 25 gallons in ten minutes. Is that right?

1 cup at a time in a 5G pail and I've never had an issue. I wait till the water is clear and then add more to 1.025 and let mix over night.

I mix 37g at a time, I measure about a 4l bucket of salt and dump it in, and let it sit overnight with a heater and powerhead. Never had an issue.
I use rodi water.

I dissolve the magnesium chloride first, dump the salt and mix with 2 1400 gal powerheads. After the salt is fully dissolved, I add calcium as calcium chloride solution and keep mixing for at least 8 hours.

I'm doing the exact same thing.
