No, either of the polyquat's I've posted links for is 60% polyquat; just get whichever one is currently cheapest on Amazon. I just checked, and the Kem-Tek product is still cheapest. If you order 2, they should ship free, and polyquat doesn't seem to go bad. I had a 55 gallon drum purchased from Buckman (the mfg of the raw material) that I used for 4 years!
Kem-Tek 60% polyquat @ Amazon
