mixing BRS soda ash into hot water

No, not as long as you add the proper amount of sodium carbonate. If you don't heat the solution up, you may not be able to get all the necessary sodium carbonate to dissolve, which would mess up the final output of alk if you don't include the solids on the bottom which don't dissolve.
 
I did this last night! Warmed the RO in the microwave for 90 seconds and was the easiest batch I've ever made. I think it should be part of the reciepe to warm the RO to 110 degrees. Each time I've done it before I stirred, and stirred, and stirred...last night it dissolved very nicely w/very little effort.
 
I haven't needed to do it, I think, but it won't hurt in the soda ash case. The sodium bicarbonate solution will start converting to the high-pH soda ash liquid if it's heated enough, but I think it'd take a while.
 
I'm not sure what you mean. It should only take a fairly short time to mix up the soda ash solution. If it doesn't dissolve right away, heating it should help a bit.
 
can yours explain to me??in randy articles i see that i put the backing soda for one hour,thanks.

I think what you're referring to is the recommendation from Randy to convert sodium bicarbonate (baking soda) to sodium carbonate (soda ash).

This process can done by baking your baking soda for one hour in the oven at 350F, thus converting it to soda ash. Soda ash (which I use) is appropriate for raising alkalinity in tanks which have a lower pH, if you choose to supplement using Randy's 2-part scheme.
 
This is an excellent idea, this last time I made my soda ash solution I underestimated how much this stuff can clump together and added it fast without heating. I ended up with a huge chunk of soda ash which was a major PITA to dissolve. This next time I am planning on heating the water up in the microwave for 60-90 secs and then add soda ash slowly.
