PROPACK Kronen KHT003 Slant Handle Holding Tank Treatment - 128 oz.

I have uses this product for the last 2 years. I have never had a smell from my black tank. I have tried a couple other products in a pinch, nothing works as good as Kronen

We are advanced RV people and have tried all sorts of cleaning and sanitizing products for our gray and black tanks. This product is the best cleaning and odor control product on the market and we have tried many. We will never use anything else and highly recommend this product. It is so easy to use and last a long time

We really like how this kills odors in our RV. IT is worth the price.

Use this product in my camper’s toilet and drains. It does a very good job of keeping the smells down and breaking down the waste products. My camping neighbor nor recommended it. She has been using it many years and I have been using it for the past 3 years. Thanks

Like the subtle, fresh clean fragrance. I’ve been using this product in the RV gray water holding tanks for about a year. After emptying holding tanks, just add recommendated 2 or 4 ozs with a little water. I have no complaints. Would recommend.

This stuff is better than the little plastic pouches.

Have used for several years. Even after the 5th wheel was being stored for months in the sun there is no odor,

Very satisfied with this Kronen product. Works very well and has a mild fresh scent - not a strong chemical smell. Would recommend this item.
