The aquarium industry is in constant flux. New equipment is always being released, new techniques are constantly surfacing. For tech savvy hobbyists, or those just wanting to stay in the now with techniques, keeping on top of things can wreak havoc on your aquarium.

There’s a great chance that things could be just fine, especially if you stay on top of the water chemistry and maintain a strict maintenance schedule, but corals don’t always respond well to big fluctuations.
