1. (Calculations based specifically on Maximum Recommended Flow Rate of 1,000gph (4,500lph) AND a total discharge every 24 hours.)
2. Eric Two units hold only 56 gallons (260 litres) water maximum.
3. ONE PASS through the unit is the time taken for the incoming water to enter the unit and exit the unit travelling as a ‘block’.
4. ONE PASS takes 3.42 minutes thus producing 420 passes per day.
5. Annually this creates a 99-mile long river!
6. Annually this river actually processes 8,760,000 gallons of water!
7. Annually only a miserly 20,440 gallons or 0.23% of the total water processed being processed is discharged to waste.

Maximum pond base coverage for good vacuum effect to the pond base at this flow rate is 2m x 2m.

1. a. At a 3-metre pond depth this is 2,650 gallons or 13,000 litres.
2. b. At a 2-metre pond depth this is 1,760 gallons or 8,000 litres.
3. c. At a 1-metre pond depth this is 880 gallons or 4,000 litres.

DAILY total discharge time represents MUCH less time taken than one miserly pass per day. Providing that the 4” bore tube to waste is maintained.
