Hi! We are finally in the home stretch of our build. We are scheduled for plaster Monday, acid wash & fill to start on Tuesday. Then Wednesday or Thursday the guy will come out to show me how to operate everything, talk about the water chemistry, etc. Should I just ignore his chemistry teachings & go with my test kit or let him get going then start testing te next day with my kit? I did a search & couldn’t find any “first time start up for dummies”. Thanks for any help!
