Frequently Asked Questions

Q: How much of this fluid should I use per tank?
Use one full “dose” as specified on the bottle (usually marked line or cap). For many cassette tanks this is enough to last about 5 days before refilling. If your tank is large or used often, you may need more frequent dosing.

Q: What does “concentrated” mean & what are its benefits?
Because it's about 2.5× more concentrated than standard toilet fluids, you get the same odour control and waste breakdown using less product. That means smaller bottle, less plastic, less weight, better economy.

Q: How often do I need to add it?
Generally, one dose lasts up to about 5 days under moderate use
