It doesn't matter if you use API, Salifert or some other test for your reef as long as A. you are testing a happy reef and B. you do it the same every time with the same brand test kit. Most people will find huge variations between brands but if it is happy keep the parameter there.
i was surprised to learn that many chalices prefer low lighting. currently i am using power compacts that are inexpensive, yet allow chalices to really thrive!
As we all know, heaters go bad from time to time. In order to safeguard against this, a temperature controller is a vital piece of equipment for the longevity of your tank. Remember, it's all about STABILITY!
many coral species have laminar growth patterns, with growth patterns like trees. The colonies are paleo-archives of water mass history and ocean water temperature.
Crocea clams can extend a thin sheet of specialized mantle tissue out of the bottom of their bassal opening, which then dissolves the substrate underneath and around the clam via chemical means. The underside of their top mantle can also be used to produce and dissolve calcium carbonate material such as their shell, coral skeleton and limestone.
REDBUGS do not lay eggs!
"They are direct developers and thus do not have a free-swimming larval stage and they do not lay eggs on the host or substrates that can later hatch."
some zoas and palys produce palytoxins that is one of the most toxic substances know only second to maoitoxin. so be cafefull when fragging z's and p's
You can have soft and hard corals live peacefully in a tank together. Just know that its better to keep them seperated as soft corals and anenomes will sting SPS and mostly likely kill them. When two corals start touching, the soft corals will release toxins to kill the neighboring coral. You can prevent a catostrophe, or at least help to prevent it, by running carbon in your tank. People are still iffy about running mixed tanks, but when done right, they are the most beautufil.
"Ammonia (NH[SIZE=-1]3[/SIZE]) is excreted by all animals and some other aquarium inhabitants. Unfortunately, it is very toxic to all animals, although it is not toxic to certain other organisms, such as some species of macroalgae that readily consume it. Fish are not, however, the only animals that ammonia harms, and even some algae, such as the phytoplankton Nephroselmis pyriformis, are harmed by less than 0.1 ppm ammonia."

Complete denitrification can be found in the anaerobic regions (bottom) of the aquarium sandbed where it is processed by specialized bacteria into nitrogen sulfide gas.
