Salinity Measurements for Marine Aquariums
@Jay Hemdal
Introduction
The fundamental difference between freshwater and marine aquariums is of course, their respective salt content. The salt level is usually reported as either salinity (parts per thousand of salt in water) or specific gravity...
Guide to Common Hitchhikers in Reef Tanks
by @A Young reefer
The purpose of this thread is to hopefully assist hobbyists in obtaining the correct id and method of treatment to common hitchhikers. Both; the good ones and the bad ones.
1) Anemones
Some times called the flowers of the sea, many...
Creating Mature Food Webs and Nutrient Processing Pathways
by @ReefGeezer
HI everyone. My name is John. I’m ReefGeezer on R2R. Here’s a picture of my 90 Gallon “Someday to be Reef” tank at about one year old. I had done some scrubbing of algae and Cyanobacteria for the picture, so it shows a...
In an industry that is always looking over it's shoulder, its refreshing news when we hear about new locations opening up and beginning to supply livestock to an evolving trade. Even more exciting when it's a country that has never before exported to the ornamental aquarium trade and we start...
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...
Hydrogen peroxide usage report
Jay Hemdal
April 3, 2021
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...
Best Fish Stores around the world: Why do reefers love them so much? Hong Kong Edition

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...
