I have been using the dilution method until my TF kit arrives tomorrow
I read in a post that I can test even further than I have. Tell me what the multipliers are, i.e.:
1 part pool water to 1 part distilled water = multiply x2
1 part pool water to 2 parts distilled water = multiply x3
What's the next level I can go to at least try and match colors on the little kit I have now.
The kit I'm using only tests the TC level to 5
