IO scare and heat?

[Canadian Man]

Anychance any of the people that have had bad batches of IO mix up have had their water tempreature go too high in the mixing container?

I am asking because I am currently mixing up 2 batches of Kent salt and I had my mag pump in one container and a mj1200 in the other. The mag pump adds more heat than most heaters can too the water and the water temp in the container easily exceeded 90F. I check the mix this morning and the container had a white film but the water was clear. I rubbed the sides of the container and I will check the alk tommorow morn.

So back to my origional question.

Thanks
