Restores and maintains the natural biological process in septic tanks, eliminates unpleasant odours
Safe and easy to use
6 x 25g Water Soluble Sachets
Simply drop a water-soluble sachet of BioGest into the toilet and flush, or drop it directly into the septic tank.
In ideal conditions a normal household tank of up 2500 litres would use 1 sachet a month. If the tank is larger, household numbers are high or chemical cleaners are used frequently, increase the dose to weekly or fortnightly.
To restore the biological balance of a tank which is performing badly, dose daily for four or five days. For best results drop BioGest in the toilet nearest the septic tank at night and leave in the bowl for 30 minutes before flushing.
