First I need to give a shout out to TF Test kits. I ordered the FAS/DPD kit Thursday AFTERNOON and got it in the US mail Saturday morning...awesome service.
So this morning I tested the FC, CC.
I got 10.5 on the FC and probably less than 0.5 on the CC. (The CC test barely turned pink and one drop immediately turned it clear again.)
When I test with the HTH OTO kit (new this season and before I was aware of TF kits - seriously ) I measure in the 4 -5 range. Sometimes the yellow may be a little higher than 5 but it never turnes orange or anything wierd.
From what I've read the FAS/DPD is very accurate and I am pretty sure I ran the test properly.
Could the differencee rally be so big? And if so the OTO test seems worthless.
