Thetford Aqua MAX® Spring Showers RV and Marine Black and Grey Holding Tank Treatment, 6 x 8-oz Liquid (96634), spring showers scent

This is great to use in your camper/rv. And does not smell too strong

Easy to use and effective. Liquified waste to make it easy to flow out of tank.

Used this product before. worked well

Have used this product for years. Disappointed I can't buy it in the store but am glad to find it online

Thetford AquaMAX Spring Shower 6-8 oz Liquid Holding Tank Treatment works very well in our campers sewer system. We add a bottle as soon as we get to the campground and each time we drain the holding tank. We, also, put half a bottle in the holding tank when we get home and the other half in the toilet bowl to sit until our next camping trip. We have had no odor problems using Aqua MAX! It is a great product and I would definitely recommend it to all our family and friends.

I have been using this product for about five years. I have attempted to switch to a few other brands and different types and always come back to this one. This holding tank treatment works really well when I'm using it we never get any smells from the black tank and I also put it in my gray tank with really good results as well. I have no issues with this product, and I will continue to use it in my RV.

We chose this over granules for a black RV tank. Does a good job despite hot temperatures and sitting empty for several months. 4 star rating is because box was smashed and arrived in damaged condition. I would certainly buy the product again!

smells good but doesn't break down waste. .... get RV DIGEST IT instead !!! my tanks flush out with more flow because theres no blockage masses now. i will never go back to thetford. camco, TST or anything else. RV DIGEST IT!!! Trust me. get small bag, try it. easy in camper toilet drop ins!

Did not do the job as far as smell was concerned. Will not be buying again.

This is the new Aqua Max formula and it stinks! Literally! This stuff can't hold a candle to the Aqua Kem original formula. i bought this by mistake and regretted it each time i put TWO bittles down the toilet just to get another day or so before needing to dump my tanks. More dumping means mire water...diwn the drain. Man, the puns are just too easy. Seriously though, this formula is garbage, and if I can't start finding the original formula in shelves soon then I will be looking for a new product to use.
