Review on 🐠 Efficient Aquarium Maintenance with S.T. International Aquarium Surface Skimmer by Cassandra Parkins

This surface skimmer is easy to mount (on an external filter). It has few details and once set it works as it should. Parts are inexpensive. The skimmer must be checked regularly to ensure that the 3 water inlets (each water inlet is then divided into 2) are clean and free of plant debris (e.g. duckweed) blocking surface water flow. 2 hands required to adjust. There are other designs that are much simpler and/or better designed. This version will not be my first choice. The rest cost the same or a little more depending on the brand they are produced under.
