Algae everywhere

I think I may have solved the issue of grey results. I was at 4.5FC. I added 4G of 12.5% to get to 35-40. However, the regional packager of 12.5% is a few towns away. So what if effective CL was much higher than 12.5? Maybe it took me to >50ppm FC? The 2006 is accurate to only 50, right? Maybe that's what happened....???? Just a thought. If so, good thing her liner is already shot!

You can test the LC with your K-2006. All you need is an eyedropper with a 1ml line marked on it--I'd get a glass one. They are still made and sold.

1) Test your tap water's FC
2) Add 10 liters of water to a 5 gallon bucket. I use an empty 2 liter Coke or Pepsi soda bottle and fill it 5 times.
3) Using your brandy-new eyedropper, add 1 ml of LC to the 10 liters.
4) Stir.
5) Measure your FC, and subtract the FC of the tap water.
6) The final FC is the concentration of the LC.

The dealer I like (the same one BigDave uses) sells LC that usually tests at 14% this way, though it's sold as 12.5%
