Happy Customers

This is just a note to tell you how pleased we are with Bio-Squirt waste tank treatment. We are Snowbirds and winter in our RV in central Florida. In the past, we used tablets. This winter we have been using Bio-Squirt.

Our typical dump cycle has moved from 5 days to 7 days. On the 7th day we are dumping due to tank capacity, not odor.

As recommended, 6 squirts into the empty tank, and 2 squirts at 5 days. We also use a squirt in our kitchen sink drain to freshen it when odor is present.

Bio-Squirt is superior to any product we have used thus far. We highly recommend it.


Randy & June

Bio~Squirt has been a game-changer for our seasonal travel trailer.

Every weekend, after emptying the black tank on Sunday, we add 6 squirts of Bio~Squirt. When we return the following Friday, our camper still smells fresh and there are no odors coming from the tanks!

It has made a noticeable difference, and we can’t help but recommend it to fellow campers around the campfire.

Bio~Squirt has become an essential part of our camping routine


Nicholas & Betsy

We tested Bio~Squirt on several large yachts including my own boat. We are very pleased with how well this controls odors. The product was very easy to use and lasted a long time. We now carry this in our marina ship store. When it comes to head odors, it’s our go to product for our customers.



Bret V.
Owner, Hi Seas Marina

We used Bio~Squirt while dry camping this last winter season. It was added to our black water tank and both grey water tanks. The 35 gallon black water tank received 6 squirts, each 35 gallon grey tank received 2 squirts of the product. The black water tank usually started to vent an odor after 2 weeks. Whenever this occurred 2 additional squirts were added. That eliminated the odor. We typically dumped black water every 3 weeks. Grey water weekly. We were very pleased with Bio~Squirt, used it from November to mid April of this year. The winter season in Arizona was unseasonably cool, not sure if warmer temperatures would have made a difference.
