Tip #3: Turn your tank into a frag rack. This is my favorite one, however, this is also the most time-consuming project. With this hack you are able to remove any piece of coral whenever you want to frag it, move it, dip it. I used to have AEFW and approximately 100 different acro colonies, I was able to dip all of my corals in a matter of a few hours. In my current setup, I do not have a single Acropora glued directly onto the rockwork, and I am able to remove all of my colonies from the tank within less than 30 minutes. Anyways, you get the point.
This hack requires some rigid tubing of different diameters. I use 5mm and 10mm versions.
Step-1, You will have to cut off about 2" pieces of a thinner (5mm) tubing and slightly melt the end of it. For this, I use an old Phillips screwdriver and heat it up, then I force the screwdriver into one end of the tube, this splits the tube into a star-shaped pattern. Or you can just glue a piece to a rubble rock if you do not like the look of the frag plug.
Step-2 You then have to superglue the thinner tubing to a piece of rock, or a frag plug.
Step-3 Cut off approximately 1" piece of 10mm tubing and superglue putty it anywhere on your rockwork. I personally use putty as it hides the tubing very well in the tank. You are also able to glue this piece absolutely anywhere in your tank with ease, due to its lightweight. After a few hours of curing, you can no place your DIY frag plug into the tube.
This set up if glued correctly can hold a coral that is several pounds in weight. I also use this set up to hold some of my Tonga branches. To make my tank mostly modular.
Here is the full shot of my entire setup, none of the acros in the photo are glued to the rock, not even the large colonies. =) well you get the point.
