Reef Aquarium Lighting

Reef Aquarium Lighting One of the most common questions I hear from new saltwater aquarium hobbyists about reef aquarium lighting is, “How much light do I need? Is there a minimum wattage I should consider to keep coral in a reef tank?” I have heard aquarists offer up the advice that to keep coral, they should have between 2 and …

Reef Aquarium Lighting: Color Temperature Experiment Results

Reef Aquarium Lighting: Color Temperature Results  This experiment in reef aquarium lighting was a visual, subjective exercise.  Rather than ramble on describing the differences between the combinations, I will let the pictures do the talking.  You can enlarge any of the pictures by clicking the thumbnail and viewing the full-sized image page.  The intent of this post is to report …

Reef Aquarium Lighting: Color Temperature Experiment Continued

  Reef Aquarium Lighting: Color Temperature Experiment Continued     A continuation of the reef aquarium lighting experiment detailed in the last thread: The color temperature of aquarium lighting is sometimes described in relative terms of ‘warm’ vs. ‘cool’.  Lamps that appear to be subjectively redder or orange are considered to be warmer color temperatures, while lamps that produce light …

Reef Aquarium Lighting: An Experiment in Color Temperature

Reef Aquarium Lighting–An Introduction to the Experiment Over the next several blog posts, I’m going to explore the topic of reef aquarium lighting.  For many reef aquarium hobbyists, lighting will be one of the most expensive pieces of equipment in their system.  Lighting is expensive to purchase and to run on a daily basis.  For photosynthetic invertebrates in your tank …

Rotifer Culturing at Home: Continous Cultures

Rotifer Culturing at Home: Continuous Culture Set-Up and Protocol Growing rotifers as a continuous culture is easy to do, but requires a small amount of work, almost every day. Unlike batch culturing, where the goal is to culture the most rotifers possible in sequential batches, the goal of continuous rotifer culturing is to create a long-lasting, stable, low-density culture.  To …

How to Culture Rotifers: Batch Culturing Protocol

Culturing rotifers at home is fairly easy to do.  Rotifers are a great food source for newly hatched fish larvae and for some filter-feeding invertebrates.  Ironically, the rotifer organism itself provides very little nutritional value to the animals that eat them. It is the content of their guts (the food they eat) that provides nutrition.  As such, it is important to …

Rotifer Batch Cultures

Rotifer Batch Cultures Culturing rotifers with a batch culture technique is akin to a manufacturing process.  Instead of focusing on creating a stable environment to keep a relatively low-density culture thriving over a long period of time, the objective of a batch-produced culture is to maximize the yield of the culture over a short period of time.  With a batch …
