Read, read again and read a third time. About my 3rd or 4th time reading all the same information, it started to make sense. I'm only on Day 7 of Spatopia but so far its been easy and fun. I keep a small notebook in my test kit and make notes for myself, measurements and chems and such. I wrote on my wall calendar for the next 2 mo. what days to do what: Mon- Spa Defender, Wed-ScumGon, Fri-Bright N Clear, shocks of 2TBL dichlor on Thurs and Sunday.
If you have not yet read the FAQ at
www.rhtubs.com I would highly recommend you start there. Lots of info.
And do searches here at this forum for the chems, you will find threads to help you.
