Local pickup only.
I've had them for about 5 months and am looking to sell both items. There's nothing wrong with them - I'm swapping them out for an upgraded filter. Both items are in excellent quality! The only foreseeable problem is that I've cut the hose to the filter myself in order to retrofit some of my stuff, so you may have to buy a new hose. You'll probably have no problem finding a new hose at Home Depot though if the current hose is too short.
Zoomed 501 Filter
Green Leaf Aquarium Inline Diffuser
I am selling both bundled for $50.00
Thanks for looking!
