GROTON, MASSACHUSETTS
Sustainably cultivated coral,
raised close to home.
We're building a small-batch coral frag farm just outside Boston — propagating vivid, healthy coral with the same care and precision we'd want in our own reef tanks. Prism Reef is coming soon.
Be the first to know when frags go live. No spam, ever.
What we're growing
Prism Reef is a small coral farm in Groton, Massachusetts. We grow SPS, LPS and zoanthid frags from our own mother colonies and sell them by mail order, shipped overnight.
Every frag is cut from colonies growing in our own tanks, so filling an order never takes coral from a reef.
We designed and built our LED grow lights, and the controller that runs them, in-house for these tanks.
Each listing will show what that frag was grown under — PAR, alkalinity, calcium, magnesium, nitrate, phosphate and temperature — and we'll post live readings from the tanks themselves.
Inside the tanks
12-hour photoperiod, run overnight on off-peak power: 1½-hour sunrise, 9-hour plateau, 1½-hour sunset.
