RLSS is a new line of protein skimmers by H2O systems featuring the speed-controllable Waveline DC pumps. Advanced Aquarist reviews the RLSS R10-U.
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.
Product Review: Inexpensive Analytical Devices: Hanna Instruments' Checkers: Alkalinity and Phosphate
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.
Product Review: Two Little Fishies' Media Reactor 150 and PhosBan Phosphate and Silica Adsorption Media
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.
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
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.
Jake highlights numerous products seen at InterZoo 2010.
Terry updates our readers on his continuing 500-gallon freshwater planted aquarium progress.
Feature Article: Elemental Analysis of Skimmate: What Does a Protein Skimmer Actually Remove from Aquarium Water?
Department of Chemistry, The Pennsylvania State University, University Park, PA 16802. The chemical/elemental composition of skimmate generated by an H&S 200-1260 skimmer on a 175-gallon reef tank over the course of several days or a week had some surprises.
Department of Chemistry, The Pennsylvania State University, University Park, PA 16802. Many factors contribute to the 'value' of a skimmer to an aquarist, including quality of construction, size, footprint, noise level, ease of cleaning, energy efficiency of the pump, and of course, the ability to remove organic waste from aquarium water.
In any case, a planted tank occasionally needs to be bushwhacked and replanted and there a few things the aquarist can do to make the rebirth of their aquarium go as smoothly and efficiently as possible.
Terry showcases a number of ways a new reefkeeper can aquascape his or her tank.
Terry discusses common types of filtration found in reef tanks.
The first 6 months of 2009 have been one of the most exciting periods for the release of new reef aquarium products.
It is vitally important that we supply our critters with water that is constantly well oxygenated through aeration and or circulation.
Feature Article: The Development of a Method for the Quantitative Evaluation of Protein Skimmer Performance
Department of Chemistry, The Pennsylvania State University, University Park, PA 16802. Protein skimmers have become indispensable for many aquarists who strive to maintain the high water quality necessary to keep stony corals.
Product Review: Products of the 20th Marine Aquarium Conference of North America in Atlanta, Georgia
American innovation and advancements in nearly every kind of product one can imagine, this year's MACNA offered attendees a wealth of new marine and reef aquarium products to gawk at and enjoy.
This month Greg shares the evolution of his 130 gallon reef aquarium with us.
Too often marine macro algae are only considered to be part of an aquarium's filtration system.
Feature Article: Granular Activated Carbon, Part 2: Modeling of Operational Parameters for Dissolved Organic Carbon Removal from Marine Aquaria
Chemistry Department, The Pennsylvania State University. In Part 2, the authors will discuss the results of their research and make some recommendations to the aquarist on its usage.
