Frag Gripper and Plant Gripper a Great New Invention

Frag Gripper and Plant Gripper

Many of you remember Bob Bittner the clownfish breeder and creator of Reef Stew. He's back with something new and pretty amazing. It's called Frag Gripper.

Just the action of moving the several year old and paly covered rocks was enough to cause the toxin to release. My son, who hadn't even touched the rocks, and I who wore gloves, were also sickened. This was from breathing the toxi...

Everything Pees and Poos in Your Tank

"Recent studies suggest that coral reefs, however, are just as dependent on these fish for key nutrients that help coral grow. When fish urinate, they release phosphorus into the water. This phosphorus, along with nitrogen excreted as ammonium through the gills of fish, is crucial to the survival and growth of coral reefs." This study highlights a very important truth in reef keeping. Every...
