Be careful to make sure the tank vent never
becomes blocked. H2O2 may oxygenate the tank contents, but it's also effervescent. In the event of a blocked tank vent, it can pressurize your tank.It also exhausts itself very quickly...so if you're only adding it to the tank "from time to time," the other products you're using will give you the same odor-free results without it.Although H2O2 in combination with K.O. and Odorlos--which isn't just a "belt and suspenders" approach, that's a belt and TWO pair of suspenders!--is harmless, not all combinations are. In fact, combining some chemical products with others or even with some cleaning products could produce gasses that are lethal...so I wouldn't recommend combining ANY holding tank products unless you know what the actives ingredients are, check with someone who does...me, for instance.
