I've never been impressed with any of these enzymatic products or mechanical tank rinsers to clean my black holding tank sensors,

Does the RV need motion for product to clean?
One packet will treat up to 50 gallons, a holding tank larger than 50 gallons will require multiple packets.
  • One or more of the packets are torn open, then the granules inside are poured through an open toilet waste valve or down a sink drain.
  • Flush/rinse the granules in to the holding tank.
  • Then fill the holding tank(s) to capacity with fresh water.
  • Let solution sit overnight.
  • The next day drain and flush tanks.
Agitation/motion is not required for this product.
