Protein Skimmers

Protein skimmers for reef tanks

A protein skimmer removes waste from the water before it breaks down into nitrate and phosphate. Our protein skimmers include in-sump models for reef systems and hang-on-back models for tanks without a sump.

How a skimmer works

The skimmer mixes air into the water to make fine bubbles. Waste sticks to the bubbles, rises, and collects in a cup as dark foam, called skimmate. You empty the cup every few days.

Skimmers are rated by tank size. However, many reefers size up a little, especially for tanks with lots of fish.

Common questions

Why is my new skimmer overflowing?

New skimmers often need a week or two to break in. Lower the water level until it settles.

Do I need a skimmer?

It isn't required for every tank. Still, it is one of the best tools for keeping nutrients low in a reef.
