"The RV Digest-It liquid is great for odor control. It might also be of some help for buildup in the kitchen drain line, without using harsh drain cleaners. To aid with the enzyme activity in the black water tank, I use this along with Unique's stick packs."
"This is the BEST RV Tank treatment! 2 in 1!!! Other treatment brands we've tried worked OK for the black tank. Digest It MAX works so well! No sewage smell in the camper and it breaks down the matter so very well. We are most impressed with how it also works for our kitchen gray tank. . . AMAZING!!! We are always so careful when washing dishes that we get as little food waist in our gray tank as possible. No matter what gray tank treatment we used in the past, we would have the most awful odor when dumping the kitchen gray tank. Digest It Max has us sold. No other tank treatment will be purchased by these campers. Buy it, you'll love it too!"
"I have only used this twice in my holding tanks. Have not had stinky issues with my grey or black water tanks. Happy Camper"
"This works great. Have used it for a few years now and would recommend it!!"
"New travel trailer. Purchased this along with a few other Unique products. No stink. No issues with flushing or sensors. Great product that will keep mom and the kids happy while maintaining your system and preventing future tank issues. Thank you. Tom"
"Love this product and love the Unique for my home but I really need you guys to be able to send it to Canada not sure what to use when I run out. Thanks"
