Pond Boss Forums AERATION Systems questions Rotary vain pump?

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.
