First I would like to thank everyone who has so kindly helped me out with all my questions and posts. THANK YOU VERY MUCH
It took 7 days for my TF100 to arrive but here is where it is now
CYA 55 (tested 2 times was 50ish 60ish (I only used half the water on first test so repeated)
FC = 5ppm
TA = 185 1st was 190ish 2nd 180ish
CH = 80
I knew something was wrong from the first drop of reagent 009 coming out of the cheap bottle.
but I continued and was little perplexed on the TA being so high .. So I retested with my other DPD kit which I always used before and
TA = 110 (which is what I've been using for weeks and what it's been reading for a while now)
I am not convinced the 0009 reagent that came in the TF100 kit is in a good enough dropper to be accurate.
The reagent they shipped came in a very cheap dropper. As soon as I started using the reagent I was like dang.. these drops are small. I knew right away that something was not right. I am not claiming to be an expert but I know consistent drops when I see them I have been testing water for over 5 years.
My other DPD test kit is only a year old and I keep it inside the house in closet.. I am careful not to contaminate reagents and I don't think the kick in the reagent is diminished.
Anyways, I wanted to mention this because I am sure that there are new people who are not used to testing and seeing the size of the drops and this was 80ppm difference in reading because of the cheap dropper. In the TF100 kit there are so many different droppers I don't think a brand new person would know the difference.
Should'nt the 009 reagent drops not be the same size as the 007 & 008 or have I learned something new today?
Anyways, based on the readings and TA being 110 where do I go now? Its been two full weeks since the black abyss and now I can see the slope from the shallow to the deep. I stopped draining /filling last Sat due to rain and work. Every day seems to be a few more inches deep of clarity. I have not backflushed the filter in 6 days and it is flowing nicely.
SO AGAIN THANK YOU FOR YOUR HELP!
