Works well
I was a little put off that Thetford discontinued Aqua Kem. This is a replacement and I've never had an issue with odoor or clogs while using it. Of course I flush my black tank thoroughly during each dump to help eliminate any substantial build up. I also put this aqua max in my tank along with 5 gallons of water every time i leave a campsite to go home. Ensuring i continue to clean the tank while driving.

It's Not About The Smell..
Our black tank was solid concrete with toilet paper.. we poured some of this down into the tank and waited overnight.. did it again in the morning and waited a couple hours and it flushed out completely.. we didn't even use half the bottle. It took very little to resolve our problems! Oh, and the smell WAS NOT BAD.. it wasn't flowery, but it sure smelt better than it had! LOL! (It works, and we use regular Scott's tissue paper.)

One of my favorites!
Versatile for casual wear, doing errans, work, church. Pretty, modest dress, comfortable for hot weather, versatile for cool nights with sweater. Easy sundress for hot days, sweater makes it dressy and modest. Wore, washed 1 year plus, both pieces look new.

Doesn't work as well as Aqua-Kem
Only controls odors for a few days, unlike Aqua-Kem which works great. Very disappointing.

Aquamax provides the best solution to order control.
Thetford make the best oder control product for Marine toilets.
