ARC Reef Live Rock

Premium Aquacultured Live Rock by ARC Reef

ARC Reef Live Rock is 100% Aquacultured right here in the US.  For every 1lb purchased we plant 10lbs. of the source material. To date, we have created over 43,500 sq. ft. of coral reef and this figure will be nearly double in 2020.


Aquacultured Live Rock has several key advantages over all other types

  • It’s a sustainable practice that helps rebuild our natural coral reefs right here in the U.S. you are also equally helping coral reefs in other countries by not creating demand for a product that is produced from destroying their own reefs.
  • Ships from within the U.S. and requires very little curing or no curing at all.
  • Premium Aquacultured products can have the same weight, density, and shapes as wild harvested Live Rock. It is important to select the right producer.

The location where the seed rocks are placed also matters greatly on the final product.  Live Rock that is placed in the Gulf of Mexico will have more plant-based life such as macro-algae. Live Rock that is placed in the Atlantic Ocean will have more types of coral growth due to the lower levels of sediment and higher par levels.  Both locations have their inherent risks and dangers from storms, wave action, and a shifting sand bed that can bury a farm’s entire crop overnight.

Our Premium ARC Reef Live Rock is teaming with beneficial nitrifying bacteria and is fully encrusted with coralline algae, corals, sponges, and chock full of filter feeders, and invertebrates. Our Premium Live Rock is the best looking Live Rock that money can buy. It has been growing life on it for multiple years.  You will not be disappointed one bit, we fully guarantee it with our 100% Unconditional Lifetime Warranty!

Coral Reef Destruction wild harvest of Live Rock in Fiji

Unfortunately, not all live rock is beneficial to our marine ecosystems. Most commonly available live rock is harvested directly from living coral reefs in Fiji and other small island nations in the indo-pacific. Destructive practices such as using dynamite and crowbars to break up these rocks into smaller pieces have decimated reef systems all around the globe. Many nations including the United States and the Bahamas have banned this practice many years ago, but the U.S. is still the leading importer of wild harvested live rock.

    This is some of the best reef live rock I’ve ever used! I wish I could post a picture, because words don’t really do it justice. It looks simply amazing in my tank.

  2. Hello,
    I purchased your pink coralline algae in a bottle. Spent a couple days stabilizing ph, temp, salt. Turned off sump and poured product in last night. This morning I turned on sump been about 12 hours and the temp dropped in aquarium by 2 / 3 degrees because sump was off and in heated all night. Tank will recover in a few hours but reading your documentation it notes temp needs to be very stable…..did I kill the spores.


    1. Hi David, thank you for your post. When we say be careful of temp swings we just mean rapid temp. changes, slow temp. changes over the course of hours are just fine, as the temps on a coral reef will change daily with current and tide changes. As long as the temp change was over the course of 1 hour or longer per each 1-2 degrees of change you will be just fine. We Hope this helps and thank you for your question.
