I have the OTO ph/ chlorine test that came with the TFT 100 but hate trying to decipher the reading. Is there a drop test or anything else that is easier to test PH? I have looked on TFT test kits and didn't see anything else for Ph.

thehowheels said:It absolutely makes a difference. You should be filling your block up to the fill line, otherwise your results may not be accurate.
See Extended Test Kit Directions. The phenol red included with your test kit is formulated to produce a result for the quantity of water up to the fill line. The bottom of the meniscus should be at the top of the fill line.
