Walex TOI11530 Bio-Pak Waste Digester

This stuff is exactly what you need for your RV black tank. Don't be fooled by the brands that only claim to "deodorize" that is a mistake you will regret. You want a enzyme/digestion formula that actually breaks down the solids. We have been full time RV'ers for many years and we know what we like and what we are sorry we ever tried. Any scent is going to work, just make sure it says it "breaks down waste".

We got these and they work great.Will buy again.

I like these because you don’t have to wait 8 hours before flushing

Works well

Best waste digester I found so far
