A while back I saw an Eshopps hang-on-tank protein skimmer at a local fish store and was pretty impressed with the build quality and how well the skimmer performed.
Now, I’ve found a video of an Eshopps PSK-75H hang-on-tank skimmer in action. These skimmers have a mesh modded impeller, along with a bubble plate to make for a really nice, but inexpensive protein skimmer.
See the video of the Eshopps PSK-75H below:
