Review on Camco 41197 TST Ultra-Concentrate Orange Scent RV Toilet Treatment - Formaldehyde-Free Breakdown for Waste & Tissue - Septic Tank Safe - Treats 16-40 Gallon Holding Tanks (1 Gal) by Kipp Amundson

I have used this treatment in the past and found it really good. Yes, the capsules are a bit lighter, but how hard is it to twist off the cap and pour out 2 ounces? Lol This is the best product I have found so far for my black water collection tank. I live alone in my van in Florida year-round. Sitting alone on the fifth wheel with a relatively LARGE 55 gallon black water tank, it takes just over two weeks to fill it up. During the summer months, the black tank just "boils" in that terrible summer heat. I have used other products that had to be reset due to odors before the tank was at least half full, even when I added more product. Or other products that require the addition of another "dose" to keep the odor down. But with Camco TST Ultra Concentrate it does the job! No odors or fragrances, it lasts a full two weeks without refills or premature resets, even during the hot and miserable Florida summer months! And the price can't be beat, you get more for your money! Highly recommended!
