Frequently Asked Questions

Q: Can I use a protein skimmer in a freshwater tank?

A: It is only advisable to use a protein skimmer in a freshwater tank in case it has high levels of dissolved organics in the water. Otherwise, protein skimmers work best in saltwater tanks because saltwater has the right tension of sea water which makes foam formation and skimming easy compared to freshwater.

Q: Will a protein skimmer remove ammonia?

A: No, it will not. Ammonia cannot be removed by a protein skimmer since it only removes organic substances. Ammonia is inorganic and it doesn’t foam that is why it can’t be removed by a protein skimmer.
