Stop Overfeeding

Stop Overfeeding! Mark’s Secret to a Cleaner Sand Bed & Healthier Fish - Mark Callahan, Mr. Saltwater Tank

Is your sand bed a "cloud of mess" every time you feed? In this video, Jimmy visits Mark to solve a common hobbyist headache: how to feed a high-volume tank without destroying water quality. Mark breaks down the critical differences between feeding a delicate reef tank versus a messy predator tank, explaining why "a little bit often" beats one giant daily meal. From the "two-sheet nori" morning routine to the benefits of freeze-dried Mysis and the importance of "cleanup crew fish" like Chromis, you’ll learn the exact schedule Mark uses to keep his 12-foot display pristine. Whether you’re keeping a Puffer or a school of Anthias, these pro tips on thawing frozen food, choosing between pellets and LRS, and managing nutrient export will help you dial in your tank's health.
