Got my TF test kit. Got some questions on the proper way to use it. First of all, is it OK to add multiple drops when it calls for one drop at a time? What I mean by this is like the test for CH when you know your CH is at least 200, is it OK to add like 15 drops, then mix, and start adding one at a time? Or should you do one at a time and mix between each one even though you will need to add 25-30 drops?
Next question is that i am getting some results for my TA and CH which vary fairly wildly from the pool store tests. In the pool store (Multiple), my TA ranges from about 100-150 depending on the store. When I tested it I got 190.. I added acid and my test dropped to 170. I am thinking I may need to wipe every few drops with a wet cloth?
Also, my CH is MUCH higher with the TF Testkit. Stores say 200-220, my test shows more like 370! Again, maybe I need to wipe off the bottles to make sure drop size is more consisent? Also, see my notes about doing multiple drops above.
Help would be appreciated.
