What is a surge?
A surge is a container that will fill up with water and at a certain point release the water into an aquarium to simulate a wave.
What style of surges are there?
The two most popular surge styles are the Borneman and Carlson surges. This site will focus on the Borneman style surges.
Why use surges?
Surges are a unique way of creating random flow in an aquarium. Surges are fairly inexpensive to make and operate compared to other water movement device’s such as close loops or power heads.
