A step up from the LD 1.5 for shallow ponds under 8 ft deep — includes 100 ft of non-weighted airline, 200 ft of weighted airline, and 2 airstone diffusers with a 2-way selector valve.
Built for shallow ponds under 8 ft deep, the LD 4.0 uses two airstone diffusers to circulate a larger area than the LD 1.5, with the added convenience of a 2-way selector valve to run each diffuser independently.
Two airstone diffusers for wider circulation than the LD 1.5.
100 ft non-weighted + 200 ft weighted airline included.
Included to mark diffuser locations for easy checking.
Protective airstone housing buckets ship with the kit.

How is this different from the LD 1.5?
The LD 4.0 adds a second diffuser, more airline, and a 2-way selector valve so you can run either diffuser independently — good for larger shallow ponds.
Is this for deep ponds?
No — like the rest of the LD line, it's built for shallow ponds under 8 ft deep. For deeper ponds, see our AerMaster Pro line.
