So bring the water up to temp, remove the heater, add half the salt, mix for an hr then add the rest. How long do u leg it mix after that?

I have heard anywhere from a few hrs to 48

"Salinity" salt mixing problems!!
 

I use salinity

I mix it the day before with the full amount all at once and leave it sit for 24hrs and it clears up

Do u get a lot of precipitate at the bottom?

salinity
 

I use the same but I mix it and use it within a few hours. It's always clear when added to tank but there is some residue in the bottom. Not much though.

Do u let it sit a few hrs before u use it or keep it constantly mixing up until u add it?

I always keep on mixing the salt till I use it (with powerhead).

Do more research!! Mix your salt as normal, put it in the tank and deal with the cloudiness for a short time. It states on the pale itself that it will be cloudy, as this is one of the only salt types that does not have a chemical in it to make it disolve faster! Instant ocean etc use a disolving agent to get rid of the cloudiness.

Speaking from experience and emails to the manufacturer directly.

Sucks. Bit outcome is much better.
