Best HOB Hang On Back Protein Skimmers


Keeping an aquarium in optimal conditions is one of the most important parts of being an aquarium hobbyist. Nothing is worse than having a cloudy tank full of all kinds of debris and waste. This is especially important if you have a heavily populated tank with different kinds of aquatic species.

Aquariums that use reefs can see a large increase in the pollution of the tank from all the waste and degraded by-products.

Although some aquarium tanks do come with protein skimmers to help clear out the waste, a major issue for a lot of aquarium owners is that their tanks do not have built-in protein skimmers. Some tanks don’t even have space at the bottom to accommodate an aftermarket protein skimmer.

This is where a HOB protein skimmer or a Hang on Back protein skimmer comes in handy.

A HOB protein skimmer is a specialized protein skimmer that doesn’t need complicated installation and can be fixed to the upper lip of your aquarium’s glass walls. It can be incredibly helpful to have this on your tank if all other options aren’t feasible. We’ll be looking in depth at a HOB protein skimmer so that you know just what to look for.
