Nuisance Algae Identification and Removal Guide
by John Maloney (2009)
Okay, so unless you have a nuisance macro algae that is complex and not normal, we hopefully got you covered. We need photos to continue the thread, send them in.
The Common Pest Algae. (Diatoms, Hair, Film, and Cyano)...
As the title suggests, this is intended as a short guide on what to do when you suspect dinoflagellates are trying to overtake your system. It is an attempt to boil down the protocols discussed across 11,000 posts in this "Are you Tired" thread along with thousands of other dino threads. I did...
A reef tank is a complete ecosystem operating with clockwork precision in a space of extraordinarily small dimensions compared to nature. As a result, the water chemistry fluctuates at a dizzying rate, implying a strategy to compensate for these changes in a sustainable manner. The export and...
Corals have beautiful colorations, whether you are after soft corals, LPS corals, or SPS corals, we believe there is a coral out there for everyone!
When choosing corals, you want to ensure they are healthy so they get the best start to their new life inside your reef tank. At R2R, our coral...
During the last few years, the technology available to facilitate the work of hobbyists has experienced an important boom. Technological advances have been transferred from the laboratories of scientific institutions, public aquariums and aquaculture companies. There is a transfer of techniques...
A reef aquarium can be thought of as a system fed by inputs, which are processed to generate biomass, resulting in outputs. The system uses the inputs for its operation, transforming them into growth of organisms and producing waste products that must be reduced, removed or recycled in some way...
The proper light for the reef aquarium is of extraordinary importance, not only for coral growth and health, but for the overall functioning of the food web. A large number of organisms involved in nutrient recycling, feeding corals and invertebrates, depend on light for survival. Photosynthetic...
Finding what corals work for you:
Trying new corals can be an exciting experience. Over one's adventure in the hobby I recommend trying a new species, at least once or twice a year to see how they perform - as well as to gain valuable experience and familiarity with new species. This strategy...

Premise:
I use 7% hydrogen peroxide for my home water treatment system. Therefore, since I always have this material in the house, I wanted to explore other possible uses for it, including:
Disease control
Water sterilization
Bleaching...

Potential Pitfalls of Using Utility Organisms (CUC) in Aquariums
Jay Hemdal
Aquarists often add “utility organisms” (animals not just for use in a purely decorative sense) to their aquariums to serve some beneficial function. These are often called CUC (Clean Up...
The Photosynthetic Active Radiation (PAR) is a term used within the reef tank community when talking about lighting. Lighting is one of the most importing aspects of the reef aquarium, partly because many aquarium organisms require lighting to maintain or increase their growth and too high of a...
Brown Jelly Disease (BJD) is an issue many reefers have run into. Like most coral diseases, the pathogen causing BJD has not been conclusively determined. Here I will share some observations and test results supporting the idea that its caused by a bacterial pathogen, and so may be treatable...
This file is a PDF copy of the book, "Aquarium Careers" written by Jay Hemdal
It offers some advice to people interested in aquariums as a career. What is a “Job”, what is an “Occupation”, and how might they differ from a “Career”? To me, a job is something distasteful that you must do in...

Hello Everyone, Steven here! Today we are starting a new exciting series by interviewing fellow reefers from around the world and compare the livestock, pricing, and some different...
Aquariums - as good for our well being and state of mind as they are for the millions of creatures that inhabit it's seemingly small, and at the same time, unendingly vast and bountiful landscape. To us giants, we see the glass box with rocks, and coral, and it's torrents of water swishing...
Teaching tangs to eat nori is relatively simple. If one fish in a tank know how to eat nori, the rest of the herbivores will learn in short order. However, if this is a new tank, and none of the tangs have seen nori before, they need to learn how to see nori as food. I normally put the nori clip...
Big or Small? Picking Out Your First Reef Tank
So you’ve decided you want to join the hobby of reef keeping…Now what? Whether you are new to the hobby or adding your 15th tank, tank size is something every reefer needs to consider before making a new purchase. Tank size is more than just the...
Hello Everyone,
Over the years, I have had a lot of questions about my tank. The most frequently asked question is not about lights, equipment, or about chemistry. The most frequently asked question is about how and what I feed my corals. When I got into the hobby in 2010, I used to spot feed...
Hi everyone,
One of the biggest challenges, for me as an amateur reefer is the numbers. Numbers are my downfall (among others). Why, do fish and coral float in nothing but numbers, and water? Po4 .03, No3 5, SG 1.027, Calcium 440, Ph 8.1, DkH 8.3, etc. I mean really, what language is that...
The Psychology of Reefing, part 2 "The therapeutic effect".
Expanded upon the first article "The Psychology of Reefing" that I wrote some time ago, there are other emotions and physical effects that we go through keeping an aquarium in our homes, that is just as important and touches upon a...
