There is a calculator on here for temp corrections so you could work it out from that I guess?

I'm sure I'll be fine! Let us know how it turns out

You are likely to damage your hydrometer if you put it in 70c water. They are not always designed for it and could crack/pop as the air expands.

Well, got an all in 64%.... considering I think I mashed too high that's fairly pleasing!

I read that traditionally, brewing water was at the correct temperature when you could see your reflection in it. At strike heat it does have a certain reflective quality, may help next time.
