  • re. HP100LL: I would like to run 2 lines from this aerator using a splitter at the pump to my 2 ponds (ponds are connected by a 4' wide opening at the intersection, ie. 7) 1 air line would be direct from the pump to the nearest pond; approx 50' from the edge to the center. The 2nd air line approx 125' from the pump, with a 2 way splitter (T) at the end, 2 air lines 50' each way (1 east & 1 west). my ponds are no more than est. 8' deep. would the air pressure be enough for these 3 air outlets?

    You would have to run a larger hiblow a HP-150 would work.
