I run two fuges and 2 DSP, mangroves in both of them. Truthfully I think that's where my success as a reefer comes from, fuges have so many benefits and are so much fun to watch.
Benefits Include:
Nutrient export.
Upstream fuges provide a constant pod supply for lower line tanks.
Slow flowing tank, great to mix with a DSP.
Fuges are great homes for pipe fish/ seahorses and gobies/ pistol shrimps.
Cheaper and much more natural than some of the products on the market.
Harvestable macro algae to sell/ give away or feed to your tangs.
MORE WATER VOLUME

.
Jail for evil crabs.
