I had a conversation with aquavitro about salinity and they also told me not to heat water. I asked them if I should take the heater out of DT also then .
To which I stumped them.

I would mix as usuall heater and pump. I keep fresh mix all the time

I have been mixing mine the day before forever and never had a problem, kinda got me wondering though....

I've been using this salt for over a year and love it. I just mix it the day before or that day WITH the heater going, and I've never seen any ill effects.

Have att'er man. I don't know why they are trying to make it more complicated that it really is...

I think few brands suggest not to use heater because of the calcium concentration. Higher calcium contrasted salts are exothermic and makes the water hot anyway and adding extra heater can cause cloudy water. Using heater after mixing shouldn't an issue and hence once the mixed water goes into the tank with heater, its no longer their concern :P
