The Pluses & Minuses of Using Activated Carbon

Activated carbon is a porous form of carbon that can be used to absorb or remove dissolved organics that give water its yellow tint. Removing these materials will help with biological filtration and increase water clarity. In theory, better clarity will aid light transmission through the water column and improve PAR (Photsynthetically Available Radiation, which is all radiation between 400-700 nm wavelength range) Does Activated Carbon Remove Beneficial Trace Elements? One of the big arguments against using activated carbon on a continual basis is that it removes beneficial trace elements from the water. I have used carbon continuously on all of my tanks and have not seen any negative side effects on my corals. This is purely an observation and not based on any scientific facts. According to

Reef Threads Podcast #303

Christine is an open-water SCUBA diver.

We return, refreshed from our holiday break. Gary stayed home and enjoyed family while Christine flew to St. Lucia, learned how to SCUBA dive, and visited some real reefs. This week we learn what it’s like as a beginner to earn an open-water SCUBA certification. It’s not as daunting as it appears. If SCUBA is in your dreams, this podcast will get you over the hump. Download the podcast here, or subscribe to our podcasts at iTunes. Also, follow us on Twitter at reefthreads.—Gary and Christine
