| A
Primer on Aquarium Filtration |
by
Leo G. Morin, Ph.D. |
| The
article discusses, in depth, the different types of filtration:
mechanical, biological, and chemical, including carbon (learn
what to look for in a a good activated carbon), polymeric
adsorbents, ion-exchangers, ammonia absorbers, bottom filtration,
and the dynamics of aquarium filtration. |

| Disease
Prevention and Control |
by
Leo G. Morin, Ph.D. |
| Despite
a long history of the use of copper, the preferred agent for
the eradication of external parasites from marine fish, many
discrordant recommendations of expert aquarists betray a limited
understanding of the basic chemistry of coppe rin the marine
aquarium |

| The
Art and Science of Aquarium Management |
by
Leo G. Morin, Ph.D. |
| Issues
covered in the article include the difference between iodine
and iodide, chlorine and chloride, ammonia and ammonium; what
is pH; the difference between distilled, deionized, and R/O
water; how do natural water environments differ; what is hardness,
alkalinity, conductivity, and specific gravity; what is a
buffer; and more. |

| The
Contrarian Reef |
by
Leo G. Morin, Ph.D. |
| Issues
covered in the article include calcium supplementation, alkalinity,
redox, ozone, phosphate, red slime, and "Berlin System."

| Marine
Water pH Control |
by
Leo G. Morin, Ph.D. |
| pH
is generally understood to be an expression of acidity or
the hydrogen ion (H+) concentration in water. The value is
a negative logarithm, which means that acidity increases as
the value decreases and that each unit change reflects a 10-fold
change. Although not totally correct, this concept serves
us well and is not difficult to comprehend. In considering
pH and pH control in the marine environ-ment, however, the
inadequacies of this concept have caused some fundamental
misreasoning. |

| Interview
with Leo Morin, Ph.D.: Activated Carbons |
|
| The
interview discusses how to select the best activated carbon
for the aquarium. It also discusses many of the misconceptions
about activated carbon in the aquarium industry. |

| Algae,
Warm Weather Foe |
by
H. Douglas Hill |
| Algae,
the most tenacious adversary with which the contemporary water
garden enthusiast must cope, is actually a symptom of a more
complex problem. Instead of being equiped with a clear cut
and direct approach for the control of algae, the pond hobbyist
is, at best, often in the dark regarding the causes of algae
growth and how to deal with the associated problems. |

| How
to Make Plants Flourish |
by
Gregory. Morin, Ph.D. |
"The
sheer number of factors involved in plant growth and health
may seem daunting at first, however, if we broadly classify
these factors into three categories the task of deciding what
is needed becomes more manageable. These categories are: Substrates,
pH/Hardness, and Supplements."
The article discusses factors affecting plant growth and outlines
the Seachem approach to creating a flourishing planted aquarium.

| CO2
in the Aquarium |
by
Gregory. Morin, Ph.D. |
| "Carbon
is the backbone of all life. Every organic molecule of every
living organism is predominantly carbon based. Given this
simple fact, it becomes clear why carbon dioxide (CO2)
plays a pivotal role in the planted aquarium." The article
discusses the relevance of CO2 in the plantd aquarium
and the options available to the hobbyist for the addition
of CO2. |

| Understanding
the General Chemistry of the Planted Aquarium |
by
Gregory. Morin, Ph.D. |
| "When
it comes to capturing a little bit of nature in our homes,
we aquarium keepers have managed to pick the most difficult
environment to reproduce. The difficulty arises from the numerous
chemical parameters that must be controlled. These include
dissolved ions, dissolved gases, pH, and waste. In an open,
aquatic system these parameters are naturally controlled through
a complex system of self-regulating feedback based control
mechanisms. However, in a closed aquatic system the self regulation
exists only very tenuously at best and can be easily overwhelmed
if the system is not adequately maintained." |
