Looking for a rotary vain air pump that can run 4 vertex 9" disks. May put in a soaker hose on our shallow ridge for some shallow aeration. 2 disks will be in one deep 12-14 foot end and 2 in the other 10-12 foot end. Shallows we hope will be 3-5 feet deep.
Will have 220v available, will plumb valves and gauges to balance pressures between each different output.
Cheers Don.

Soaker hoses produce very small bubbles and work good for a while, but those rough surfaces and small pores quickly clog and cause pressure increases back at the pump. Rotary vane pumps do not 'like' this. Be watchful. Consider a tube membrane bubbler or a homemade punched or drilled vinyl tubing diffuser with check valve or a single 9" disk diffuser for the ridge diffuser. Or split one Vertex diffuser and run one disk in the smaller basin and one on the ridge. Check Canada eBay for rotary vane compressors.

For the small 0.5 acre pond a 1/4hp unit is very adequate providing plenty of cfm for mixing the two basins and the underwater ridge. In my experience on the reduced scale, one 9" disk diffuser in each basin would adequately mix each basin. The ridge will mix naturally down to about 5ft deep in your area. Beyond that depth a little bubbling from a shallow center diffuser will help blend the two basins. Shipping a unit to you from the US will be costly, you should be able to find a source in Canada.
