2,000gal SPS Dominant Reef Tank in Minnesota

The BIGGEST in-home saltwater tank on BRStv!

2000-gal-reef-tank-Orphek-Atlantik-V4-Gen2

Enthusiastic reefer and coral collector from Minnesota, Sean Kramer started at fifth grade (!) with fresh water tanks and has been the proud owner of this impressive 2,000 gallon tank, measuring 22 ft long (22 x 4 x 3 ft) filled with SPS corals for 5 yrs now.

This outstanding reef tank is lighted by 24 units of our Atlantik V4 Gen 2 in a custom made layout for full coverage of the tank and even light spectrum spread:

Sean has an extensive knowledge today on how to grow SPS and loving challenges, he brought an extensive collection of SPS stick corals into his tank, which is also a grow out tank for Top Shelf Aquatics.

Many of the colonies they frag are sold in Top Self Aquatics shop, since Sean is more into collecting rare species rather than letting the corals grow to their full capacity.

Sean also has a frag tank in the maintenance room to keep frags out of the main tank. It was used before as a quarantine, but now he uses mostly as a nursery tank. FYI, land-based nurseries require a LOT of experience and training in water chemistry and aquarium husbandry.

Seans nursery is using 2 units of Atlantik V4 Gen 2 with Orphek LED spectrum for better coral growth, color and health.

As per Orphek spectrums, it is interesting to notice that such an experienced hobbyist as Sean understood that Orphek LEDs are a much better option to substitute T5s!
