THIS 70 GALLON ARAGOCRETETM AND GLUE REEF IS ONLY 24 HOURS OLD IN THIS PICTURE
Most of the aragocreteTM rock is less than two weeks old.

The tank is set up using 3 arches, 4 caves and several ledges. The sand is still 80 percent open to the water flow. We call this the SMALL FOOTPRINT REEF

We are putting mushroom rocks in the caves. We will move them as soon as the mushrooms grow onto the cave.

SOCKET ROCKS CREATE A FINISHED LOOK

We want to share with you one of the first 'New' reef products that has been introduced to the hobby in several years. There have been new skimmers, pumps, and filters, but we have had skimmers, pumps, and filters. The AragocreteTM and Glue reef project is new way to make reefs from scratch using nothing from the wild ocean.

This is a new product that can be started with very little money. You can market dry rock in your area while your brood stock is growing. This product is a great one to trade for Ice Caps and Gemini pumps. You are only limited by the size of your local market.

I am receiving more and more data on ways that people are making these rocks. If you think of some new ideas please share them with us so we can get others growing their own reef.

We have more questions about making Aragocrete than almost any other subject lately. AragocreteTM is a very exciting product because it can be made almost anywhere, and the market for it seems to be immense.

Properly cured Aragocrete that is made using our recipes and techniques makes a porous, lightweight, and attractive live rock. We have been operating many of our reefs with only Aragocrete artificially made the live rock for four years.

When I started this project I have to admit I was most interested in finding a way to reduce the demand for wild collected live rock. In all of my studies of marine biology it was always stressed that in healthy tropical marine environments literally every piece of substrate would be colonized.

In the 1970's I was very worried that our hobby would reduce the number of tropical fish that live on our reefs. My research led me to some studies that were done in the Caribbean and the study showed that as long as the habitat was there it did not seem to matter how many fish were removed from an area.

THIS IS THE SAME TANK A YEAR LATER

It seemed logical, that within reason, there would be more potential baby fish on any reef than there would be hiding places. One of the studies is most memorable because it relates directly to the aquarium trade. An area was marked off with ropes and for a period of several years the commercially valuable tropical fish were harvested. At the end of this test period each of the available habitats were refilled with growing tropical fish.

Much of my work in fresh Water fish management has had to do with creating habitat structures. It seemed to me that if we left the structures and the live rocks on the reef we will be able to harvest the fish and invertebrates in a sustainable manner.

ARAGOCRETE BASICS

This is an easy, inexpensive product to produce and test market. You can get started by purchasing one bag of cement and one bag of gravel. I cannot think of another product that you could manufacture for the local salt-water market that would be easier to start than AragocreteTM rock manufacturing. The AragocreteTM can be manufactured in tropical fish Styrofoam boxes and these boxes can be moved and stacked while the Aragocrete is curing.

The only problem you'd have with manufacturing Aragocrete in an apartment would be finding a place to soak it in fresh water. One particularly enterprising young student told me that he had found the perfect place to cure his Aragocrete Reef Plugs. In a recent e-mail he said his method of curing them was as simple as hanging some reef plugs in the toe of a nylon stocking in the back of his toilets. He said his mom had not noticed and that everyone helped him change water several times each day.

THE BASIC RECIPE FOR ARAGOCRETE:

ONE PART WHITE CEMENT
5 PARTS ARAGONITE GRAVEL
ONE PART PLASTIC SCRAPS
ENOUGH FRESH WATER TO MOISTEN

SIMPLE ROCK MAKING:

1. DIG NICE SHAPED HOLE IN SAND
2. MAKE A DRY CEMENT MIX
3. FILL HOLE AND COVER WITH SAND
4. DIG UP AND SELL THE ROCKS
5. REPEAT

This is the absolute bare bones method of making Aragocrete. If you're interested in more details there are many articles in the back issues of reef aquarium Farming news. I do want to explain some of the simple things get you can do to increase the production of live rocks.

Here are some great links to help you learn more about making rock.

MAKING FANCY TYPES OF HAND MOLDED LIVE ROCK
ARAGOCRETE RESEARCH BY TRACY GRAY

PLANT CORALLINE ALGAE ON ROCKS;
This may seem like the very simplest thing but it is something that many people forget to do. When you start a tank full of live rocks it is very important that you put Coralline algae into the tank. We use our own GARF GrungeTM in every batch of rock live rock that we make. You can remove Coralline algae from the glass of any of your other aquariums and put it on top of the new rock. This Coralline Algae will start to grow as soon as it touches down.

USE MAXIMUM WATER FLOW RATE
One of the things that we've noticed consistently about Coralline algae growth is that it often thrives in fast-moving water. If you can add more power heads to your rock grow out tanks I am certain that you will find that your coralline algae does very well. In our new greenhouse we will be using airlifts to create a low-cost high-volume water flow.

REMOVE EXCESS PHOSPHATE;
Keeping the Phosphate level very low will help the Coralline grow. Phosphate is known as a crystal poison and it has an inhibiting effect on the formation of the calcium skeleton in the Coralline algae. We use a product from SeaChem called Phosguard and it is very effective at dropping the Phosphate level in the water column to very close to zero.

INCREASE CALCIUM;
Keeping the calcium level above 400 parts per million is very important. Coralline algae uses a lot of calcium to deposit it's skeleton so you have to continually add Calcium to the grow out tanks. One of the least expensive ways that we found to do this in large tanks is with the use of pickling lime -Calcium Hydroxide. We do not use this in our systems because it is better to apply it to the tanks as a drip. We have to take care of many individual systems every day and we have found out that things go much faster when we use SeaChem products. We are thinking about adding a drip system to our 1,000 gal. grow out tanks in the new greenhouse.

USE SUFFICIENT NUMBERS OF HERBIVORES;
We have left the most important part for last because we want to discuss it fully. Using the proper number of herbivores to keep the pest algae in check is one of the most important things you can do to ensure the quality of your product. We use a combination of snails, hermit crabs, and Tangs in all of our grow out tanks. The only problem we have is that we also sell Reef Janitors and often the herbivores are removed to fill the orders. It is absolutely the easiest thing to tell when one of the systems has been over harvested. As soon as we start to notice algae a quick inventory of the Janitors shows that too many have been removed. We now use 1 and 1/2 mixed hermit crabs and snails per gallon and two small tangs in each 55 gallon tank.


You can see how the finished socket rocks are used to finish an AragocreteTM and Glue reef.

The coralline algae moves off of the socket rocks onto the rest of the reef structure.

SOCKET ROCKS HOLD THE CORALS AND PREVENT THEM FROM FALLING OVER

The ledges give us lots of room to glue sps corals near the lights.

THIS SPS CORAL PLUG GROWS SO FAST THAT THE CORAL TIPS OVER THE SMALL ROCKS WE RECEIVED THEM ON.
We invented the socket rock so we could plug the sps corals into a coralline covered rock that would hold it up as it grew.

Many sps coral die because they fall onto other corals. This method can prevent that from happening as often. SOCKET ROCKS SELL VERY WELL BECAUSE PEOPLE CAN MIX AND MATCH THE CORALS



plugs These are some of the Reef PlugsTM that we grow to place in the socket rocks. It is very exciting now that we have many finished reef sockets. I remove the reef plug from them and the colony of inverts has grown onto the rock. It is most fun when an sps coral does this. Then you have a cave with coral growing around it. You then move the plug into the next rock. sps plugs


STEP 1.
Take the plug you are making the socket hole for and cover it with three layers of plastic.

STEP 2.
Each socket rock is made by placing one hand full of AragocreteTM on the damp CaribSea gravel.

STEP 3.
Insert the covered plug into the wet AragocreteTM and then cover the rock with CaribSea Aruba Shell or fine aragonite sand.

Wait one half day and then remove the covered plugs from the firm AragocreteTM.

STEP 5.
Push your finger all the way into the socket hole and finish making a tunnel.
