|   Yes, assuming they base on 20,000 litres/hour about 5300 gph. (I'm looking at a closed loop on a big tank) |

|   Just wondering if anyone had success controlling the speedwave or waveline using their apex - more specifically using it to control the speed of the motor (not just on/off obviously). |
