I'm not entirely sure the tank tours will be Sat anyway, possibly Sun as well, as Sat could get quite busy with store tours unless we do those Friday....hmmm...so it's kinda up in the air right now.
I'll pm the address for those who want it.
We have a refract too, bring yours anyway Steve and we will compare readings ! Ours is a temp corrected hydrometer, which I believe most are.
