Are the chemical companies diluting their chemicals more than they have in the past? For the life of me, I can't get my new batch of Tri Foam to "foam" at all. I haven't changed a thing on the automatic either... I've turned the Blue and White pumps up, for those of you that use them, I used to run at 3, I'm up to 6 now. The water pressure is 30 psi and the air is at 25 psi. I can get the blue to foam a bit but nothing out of the yellow and red. I checked everything I can check and it is all working. I'm starting to think the chemicals are watered down. I use both Warsaw and National brand tri foam from Kleen Rite. Any ideas?
