I stumbled across this thread looking for something else and thought I might add my 2 cents as I have had a few customers try to add KDF to a Sanitizer just like you did to no avail. When you pour in the KDF all at once on the top it will act like a plug and ride up and down during backwash and will not typically settle to the bottom. The proper way to add KDF (and it should be 16 pounds in a 10" tank to create a 2" layer) is to poke a bunch of holes down into the CR100 and then pour in about a 1/3 of the KDF, then poke more holes, pour another 1/3, poke more holes and pour the remaining third. Then put the unit into backwash and the KDF will fall to the bottom. In your case I would try to poke as much down into the bed as you can until you see a lot of white or at least a good mix and then put the unit into backwash. I would also confirm the DLFC is a 7GPM and that the numbers face toward you when you remove the clip on the DLFC housing to check the flow rate. Good Luck!!
Wow....that makes a lot of sense, the rep from the regional district after a call to the US
headquarter did mention the "plug" behaviour and after opening it up this afternoon, That's exactly
what it looked like.
So far the HQ for a solution has only suggested basically a re-bed and if it comes
to that I will go with your suggestion befor blowing more money on media, considering that
it only have 6 months usage .
DLFC is what???
Thx for dropping in....
