EasyPro QS1 Quick Sink Self-Weighted Diffuser Assembly for Lake & Pond Subsurface Aeration/Low Maintenance Single EPDM Rubber Membrane

This bottom diffuser is high quality components. The only item that would make it better would be to add a 6” extension to get disk off of bottom so it doesn’t draw sediment. I added my own.

Similar to a few other purchasers of this product the diffuser broke off from the base. It just happened one day after having been in the same spot in the pond for a year. I contacted EasyPro and they took ownership of the issue and the solution in the first communication. 3 days later the diffuser is good to go and most importantly our ponds and koi are smiling.

Working good when running

Shipping really fast, easy to install, works really well with my windmill aerator.

Great

I bought 3 of these aerators. Quality seam good till I noticed it wasn't bubbling correctly. Went to the hardware store and was able to use a 3/8" ID x 1/2" MIP brass fitting and a 3/4"MIP x1/2" FIP to replace the broken fitting. I no longer have a back flow stop but at least it's working again. Other than that the units work great.

THIS is just what my outside koi pond has been wanting! I was using a smaller type of stone diffuser and always ended up replacing them the next season. THIS baby is bigger, and I LOVE the weighted base and the secure fittings that keep the hose line intact. This is my first winter with it (and I live in Northern Vermont with brutal winters) so I'll update come Spring, but from what I'm seeing I have every confidence that this will deliver.
