Grey Tank Water Treatment?

[cre10]

Anyone put anything in their grey tank? I use Kronen in my black tank. I saw in a catalog the other day there was treatment for grey tanks to reduce grease build up and whatever else. Is this really necessary?

I can't believe no one has jumped on your post.

We use the powered water softener and laundry
Detergent method.
mostly for smell and to help keep build up on probes
clean.
so yes I would.

I drop three DAWN dishwasher packets in the sink with warm water to be added to the gray tanks (both gray tanks) I also add three packets to the black tank. Just place the three packets in the POOP bowl with a little water, let dissolve. Keeps my tanks clean with no water spots!
