Feature Article: Toxicity Of Trace Elements: Truth Or Myth?

By Habib Sekha (Salifert) on May 14, 2003 at 08:00 PM

In this article I will explain that it is not always necessary that a heavy metal is toxic since this depends strongly on the form (=speciation) in which it is present. That is it is not always bio-available

Feature Article: Silica In Reef Aquariums

By Randy Holmes-farley, Ph.D. on Jan 14, 2003 at 07:00 PM

Why would I recommend dosing silica? Largely because creatures in our tanks use it, the concentrations in our tanks (at least in mine) are below natural levels, and the sponges, mollusks, and diatoms may not be getting enough to thrive.

Chemistry And The Aquarium: Boron In A Reef Tank

By Randy Holmes-farley on Dec 14, 2002 at 07:00 PM

This article also discusses the sources and sinks for boron in reef tanks, and shows that while typical tanks may be slightly depleted in boron with respect to natural levels, most are not so significantly depleted that any correction is required. Nevertheless, how to test for and supplement boron is addressed.
