Bio-reporter Initial System Dosing

If a pellet feeder is used for large systems (larger than 160,000 gal) start-up of 3D TRASAR Bio-
Control requires the manual application of an initial dosage of bio-reporter chemical. Use Quick
(P/N 460-3DTBRC.87).
Dose Pouch
Refer to the chart below and find your system's total water volume. Read across to the "# of
Pouches Required" column. Add this number of packets to the tower basin by carefully placing
them in the water at a point of good circulation and turbulence. The packets will quickly dis-
solve in the water and release the bio-reporter contents.
If the system volume is less than 160,000 gallons or 3DTBR10 is used as the bio-reporter product,
no pouches are needed (simply initiate 3D TRASAR Bio-Control as instructed in Section 6.3
above). The Liquid Pump or Pellet Feeder will automatically feed the correct amount of bio-reporter
to the system.
If pouches are unavailable and your system size exceeds 160,000 gal use the following table to
calculate startup dosages. It is imperative that the startup pellets be placed in a region of good flow
so that they dissolve quickly (do not dump into a slow flowing area in the tower basin).
