Chemicals for mixer and sanitation sink and how to verify.

Our company has decided to alternate sanitizers monthly. We were using Sanitime only and a wall mixer. I validated concentrations using QUAT color strips. It was suggested we use AlPet D2 as our alternate monthly sanitizer and simply change the feeder tube from the mixer from one 5-gallon container (Sanitime, AlPet D2) to the other at the end of the month. Since beginning this system with AlPet D2, my QUAT strips are always negative. I see there is an AlPet D2 QUAT-free, but this is not what we have.

Questions:

1. Do I need a different validation than Quats for AlPet D2?

2. Can Alpet D2 be used in a wall mixer for the sanitizing sink? Getting worried this might not be a valid use...

Sorry if this is a really basic question. Trying to learn...

Alpet D2 is almost always a non mixed product - use as is.   Do you have one that requires dillution?   

I love allpet for places where using water is discouraged / dry environments.  its not the best solution for a sink.   Its stupid expensive.   If you want to use it, I would say just get the spray botlles and spray it on anything you want to sanitize.  no need to test the dillution as its "predilluted" by MFG.
