As a passionate hobbyist, I am often looking for innovative products for my aquariums. A few years ago I found company that made great frag racks for aquariums. The Alternative Reef creates unique handcrafted ceramic frag racks, which are also sold with a powerful Magnet built in so it can be attached to a glass wall or overflow, which require no curing and will color up with Coraline algae quickly. I personally own 3 “Magnetic Frag stations” which I have magnetized to the overflow for additional grow out space and more.
Check out their website, you will like what you see!
Here is a picture of my first Magnetic shelf Rock that I purchased.
