Review on Valterra V23021 Blue Pure Power by Deron Altman

These bags were packed very tightly and I almost couldn't break them down into a powder. I don't know if this is normal as I have never tried this brand. There have been many reviews of how I cleaned the sensors and I haven't had much luck with it. I filled a black and gray tank with this chemical and then let it sit for a few days before flushing the tank. I've done this twice and haven't had good results with the sensors. I don't think I would buy them again.
