Why TerraReef?

Sustainability

We try our best to reduce waste, lower our carbon footprint, and source sustainable materials when possible. These are not just catch phrases we're using, but something we believe is important.  

Quarantine

We go to great lengths to try to achieve as close to “pest free” / “clean” corals as possible, but no reef aquarium on the planet is perfect. We recommend everyone quarantine corals from any source.

At TerraReef, all new corals, algae, and other invertebrates introduced to our systems have been quarantined in fishless tanks for more than 90 days. Long term observation can be extremely helpful in finding pest organisms.  We intensely observe these aquariums for pest, we always dip, and we will usually remove all rock and plugs in an attempt to only add the coral to our systems and nothing else. We quarantine everything wet unless it comes from one of our few trusted suppliers operating biosecure facilities.  We have fish in our systems that are family pets we wish to protect.  An ounce of prevention is worth more than a pound of cure and each hobbyist must choose what is best for them and their tank.

We can confidently say that no Aiptasia, Majano, red bugs, pyramid snails, rice snails, or nudibranchs will be included with your order.  It is possible some critters you may not want will be included such as asterina sea stars, bristle worms, and vermetid snails as they are present in our systems. All corals for sale have been with us for a minimum of one year and most over ten years! 

System Information

As of 2025 we run two main systems for coral propagation / display, a ~885 gallon systems and a ~480gallon system.  We run our tanks sort of like a modified Triton / Moonshiners methodology, but with so many alterations might as well say our methodology is our own.  Important to our coral customers we should share we run our "nutrient levels" Nitrate/Phosphate between typical hobbyist and ocean levels.(we target 0.06ppm Phosphate and 1ppm Nitrate though Phosphates often get a bit higher and Nitrates are often closer to 0.2ppm)  Helped by both dark and brightly lit refugiums and low fish stocking our systems are full of "pods", mysis, and other plankton.  Most corals listed on our site have had 4-6 weeks to recover from fragging and start to grow significantly.
