LED lighting for reef tanks is on its way to becoming a reality, and various designs and configurations are making their way into the market.
Raul will give you the necessary information, presented at a layman's level, to get your reef aquarium up on the Internet. The Internet accessible aquarium will be discussed here from the standpoint of two particular pieces of equipment, the aquarium controller and the network webcam. Read on to see how it's done.
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
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.
To summarize, it is impossible to give a single number recommendation when it comes to tridacnids' lighting requirements, even for a particular species. Each clam is genetically different, and some members of a given species will need more light than others.
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.
Equipment Review: Inexpensive Aquarium Thermometers - Bargains or Reef Killers? Plus Notes on Thermometer Calibration
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?
How do you provide circulation for the critters under your care?
Jake highlights numerous products seen at InterZoo 2010.
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.
LED lighting for reef tanks is on its way to becoming a reality. Different LED fixtures address the lighting problem in several different ways, small number of high power LEDs with optics or with large numbers of low power LEDs with no optics.
Based on personal observations of corals' minimum and maximum light requirements using a Pulse Amplitude Modulation (PAM) fluorometer, it appears that the Blue Moon Aquatic 90-watt LED unit is capable of meeting the maximum light requirements of the most demanding corals. Read more for the details.
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.

Let's hear what YOU have to say about lighting advances in today's hobby.
Feature Article: Quantitative Comparison of Lighting Technologies: Metal Halide, T5 Fluorescent and LED
Based on this quantitative data, is its quite obvious that the LEDs have come of age in providing a viable solution to lighting reef aquaria.
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.
Product Review: Reefing like it's 1999: How Reef Aquarium Flow and Lighting has Changed Over the Past Decade
Jake takes a walk down memory lane recounting how lighting and water flow has changed over the last ten years in the reef aquarium hobby.
This article presents a review of the spectral analysis and light output of these lamps when used with a wide variety of ballasts.
