20 Best Cheap Protein Skimmer (2022 Updated)

A cheap protein skimmer is a device used to remove dissolved organic compounds (DOCs) from aquarium water. Aquarium water is pumped into the skimmer where it is mixed with air. This creates a foam that traps DOCs.

The foam is then collected and removed from the aquarium.

Conclusion

A protein skimmer is an important piece of equipment for anyone keeping a saltwater aquarium. A protein skimmer removes dissolved organic compounds from your aquarium water, helping to keep it clean and clear.

Protein skimmers come in a variety of sizes and styles, so it’s important to choose one that is appropriate for your aquarium. If you have a small aquarium, a hang-on-back protein skimmer may be a good option.

For larger aquariums, a canister protein skimmer may be a better choice.

Protein skimmers are relatively easy to use, but it’s important to read the instructions carefully before setting one up. Once you have your protein skimmer up and running, be sure to clean it regularly to keep it in good working order.
