Written by Tim Wijgerde and Jan Korbijn Coral reefs; what exactly are they?

Coral reefs have formed through the mineral deposits of billions of small invertebrate animals, called coral polyps. All of these polyps live in colonies, which can consist of one to many thousands of individuals. They are able to build houses made from calcium carbonate, called aragonite; similar to the bones in our body. They can retract themselves into their little homes when attacked by predators. Over millions of years, these animals have been able to create vast underwater mountains which we now call coral reefs.

It's ALL gotta go!!* Nitrate (NO3) reduction is directly proportional to percentage of Water Change. Allen's home-made formula...currentNO3-((%WC.01)currentNO3)=finalNO3 (thanks Luukosian) This means if you change 50% of your total water volume (That's EVERYTHING) you'll get a net reduction of (NO3) somewhere around 50%. Ask me about how to increase your REEF budget without going without FOOD!!* Big Al's 10g Julie's (BigAl's Gal) 6g NanoCube Gone but not forgotten BigAl's Slow 90g Tank Chronicle Allens OFFICE 12g Nano-Reef
