Aquarium Fish: Chloroquine: A "New" Drug for Treating Fish Diseases

By Jay Hemdal on Feb 20, 2013 at 11:00 AM

While not a panacea or miracle drug, chloroquine is experiencing resurgence in popularity for use in fish-only aquariums and quarantine systems to treat a variety of problems ranging from Cryptocaryon to Aiptasia anemone infestations.

Aquarium Chemistry: Phosphate And Math: Yes You Need To Understand Both

By Randy Holmes-Farley, Ph.D. on Mar 21, 2012 at 09:00 AM

Foods are by far the most important source of phosphate in most aquariums. In considering whether sources of phosphate other than foods are important, one must carefully look to the actual amounts involved to determine whether other sources are even worth trying to minimize.

Feature Article: Spectral Distributions of LEDs: AI-Sol, Radion, Orphek, EcoRay, Mvava

By Sanjay Joshi on Mar 07, 2012 at 10:00 AM

In addition to the characterization of light by its intensity and distribution, the spectral distribution is also of interest. Light sources emit light at varying amounts at different wavelengths. Spectral distribution characterizes the light output across different wavelengths of the light spectrum.

Aquarium Chemistry: Effects of GFO (Granular Ferric Oxide) on 'Trace' Metals Concentrations in Artificial Seawater

By Dana Riddle on Feb 15, 2012 at 10:00 AM

Granular Ferric Oxide (GFO) is popular among reef hobbyists as a means to decrease phosphate levels and subsequently algal growth in their tanks. GFO, however, can also affect other ions and compound levels as well. In this article, Dana investigates the effect that GFO has on our tanks outside of decreasing phosphate levels.

Aquarium Chemistry: Calcite, Aragonite, Limestone, and More

By James W. Fatherree on Oct 26, 2011 at 08:00 AM

It's been said a million times that aragonite helps buffer aquarium water, or helps maintain calcium concentrations, while other (carbonate) substrates do not. However, to the best of my knowledge this simply isn't true.

Product Review: Inexpensive Analytical Devices: Hanna Instruments' Checkers: Alkalinity and Phosphate

By Dana Riddle on Aug 24, 2011 at 08:00 AM

In many cases, results from colorimeters are superior to visually judging colored samples. Will an inexpensive device deliver results comparable to an expensive spectrophotometer? Dana tests the Hanna Checkers to find out.

Feature Article: Experimental Comparison of Measured Flow Output of Aquarium Propeller Pumps

By Michael Sandford, William Straka, Sanjay Joshi on Jul 13, 2011 at 08:00 AM

Hobbyists have seen significant advancements in the range of aquarium circulation pumps available over the past decade. While all manufacturers provide a flow rate for the pumps, it is not clear what methods have been used to arrive at the numbers. Further, different manufacturers may use different methods. We have presented a standard method that we hope can be adopted by the manufacturers thus enabling a more accurate and verifiable approach.

Product Review: Two Little Fishies' Media Reactor 150 and PhosBan Phosphate and Silica Adsorption Media

By Dana Riddle on Jun 15, 2011 at 08:00 AM

TLF's 150 Reactor and PhosBan media performed as advertised. Under the conditions of this testing, both phosphate and silica concentrations fell to levels below the detection limits of 'laboratory grade' instruments. The successful application of these products in aquaria around the world is a testament to their functions. If you're battling algae outbreaks and need a quick solution, give these products a try.

Aquarium Chemistry: The Nitrogen Cycle: New Developments and New Prospects

By Marco Colasanti on Apr 19, 2011 at 08:00 AM

So far we have always thought of the nitrogen cycle as a series of linear reactions that conclude in a circle. But is it really a cycle? Important discoveries made in these recent years have drastically revolutionized this concept. In this article, I will try to discuss some of these research studies, with the intention and hope of being able to make this complex topic, understandable.

Feature Article: Bacterial Counts in Reef Aquarium Water: Baseline Values and Modulation by Carbon Dosing, Protein Skimming, and Granular Activated Carbon Filtration

By Ken S. Feldman, Allison A. Place, Sanjay Joshi, Gary White on Mar 02, 2011 at 08:00 PM

What are the bacteria populations in the water column of reef tanks, and how does that value compare with bacterial counts in authentic reef water? Does carbon dosing indeed increase water column bacteria populations (i.e., is growth carbon limited)? Does mechanical filtration (protein skimming and/or GAC filtration) actually remove bacteria from the water column, and if so, how much? Ken, Allison, Sanjay, and Gary's in-depth article puts these questions to the test.

Aquarium Chemistry: Regeneration of Granular Ferric Oxide Media with Sodium Hydroxide

By Matt Wandell, Laura Kormos on Oct 14, 2010 at 08:00 PM

For aquarists who keep non-photosynthetic corals that require massive feeding, have large tanks, or a dense fish population the costs of regular GFO replacement can be significant. With a few simple tools and techniques we can easily regenerate GFO so that it can be reused several times over.

Feature Article: Types of Phosphorus in a Reef Aquarium and Comments and Observations of Removal by Protein Skimming

By Dana Riddle on Oct 14, 2010 at 08:00 PM

This testing makes it clear this protein skimmer did remove phosphorus, although the process may not be particularly effective as a sole method of P control, and phosphate could accumulate in the system if other removal mechanisms are not used.

Equipment Review: Inexpensive Aquarium Thermometers - Bargains or Reef Killers? Plus Notes on Thermometer Calibration

By Dana Riddle on Jun 14, 2010 at 08:00 PM

It is not uncommon to see an aquarium housing hundreds (or even thousands) of dollars worth of exotic animals while using a very inexpensive thermometer to report this critical parameter. Is this practice a shrewd use of financial resources, or frugality inviting disaster?

Product Review: B-Ionic Seawater is Good to the Last Drop

By Jake Adams on May 14, 2010 at 08:00 PM

As with trying and testing all new things, long term performance is what really counts so I was greatly looking forward to seeing if my initial impressions with the 4-part would be similar to my long term experience.

Feature Aquarium: EcoReef One: A New Kind of Nano Reef

By Jake Adams on Apr 14, 2010 at 08:00 PM

The description of this tanks sounds like a list of things not to do when setting up a reef tank: it has no live rock, no live sand, minimal filtration, no additives, the water is never tested, 100% water changes and yet this 5 gallon glass box is one of the most attractive, successful and least demanding reef tanks that I have ever set up.
