Ok i just mixed 15 gallons of IO for a water change. Normally when i mix io it does not stay cloudy. I have a maxijet in since around 11 last night. It is now 10:11 here and it is still cloudy. I dont have a heater in the water should i?

Test the water for Ca and ALK. There has been a rash of excessively high alkalinity from IO salt. Precipitation would be the primary indicator.

well heres what i did,
I put the amount of salt in the rubbermade. Then i put maybe 1/2 a gallon of water in the bin. I thought i had more water but i did not. The mixture was a thick paste. 1 day later i went and got my proper amount of water. I added it and i noticed some foam, but i thought it would be because of the pasty junk. I ran a powerfilter and powerhead after i noticed the cloudiness. It went away in about 10 minutes. Would the foam be associated with the paste or the alkalinity and ph?
here are the readings for the water.
ph is 8.2
the alkalinity is low (my test just tests a range not specific measurments)
is this ok? i know the ph is reasonable but should the alkalinity be better?

ahhh.. ok I see now.
ALWAYS...always add the salt to the water while stirring vigorously.
What happened...
You added a small amount of water to a bunch of salt. The Calcium and BiCarbonate levels exceeded what the water could hold so it precipitated and formed tiny crystals of CaCO3 (Calcium carbonate). It's these crystals that are keeping your water cloudy. They will not dissolve unless you get the PH below 7. If you tested Magnesium, it too will be very very low.
Throw out that batch of saltwater and try again.

Waste of money? Be thankful you didn't go ahead and use that batch. Let us know what happens with the next one.
For the record I always put the water in, turn on heater and power head, then add the salt.

Actually Thank You Aarone, at least someone has given some feed back on testing their water change water before adding it to the main tank, sounds like you still need to do this again and I would really like tok know what happens.

no problem. IO says phosphate free but when i tested it had small amounts of Phosphates. Hmm oh well i still like IO.
My next change i will post back with the readings.

It's possible that your positive DI rosins are near capacity.

oh that could make sense. I buy my RO/di from the grocery store, no telling how much they are used. My sister tests groundwater for a living (rock nerd) and i had her test the water to make sure it was good stuff. It tested ok for all minerals and regular deposits. but im sure as time goes by it lets more and more through.

Use a funnel so it slowly goes into the water. Thats what i do, then i turn on the power head....Maybe i should turn the power head on first :)
