Aiptasia are tropical sea anemones which are commonly found in marine aquaria. Usually introduced as hitchhikers on live rock, they rapidly colonize the aquarium due to their prolific growth. Although Aiptasia may settle on any available substrate, chemical signals may attract them to specific microhabitats. In this article I report on the settlement preference of Aiptasia for cyanobacterial mats, a finding which suggests a three-way symbiosis between sea anemones, dinoflagellate algae and bacteria.
Although a tank with temperate marine macro algae as the primary focus may be unheard of in the aquarium hobby, all of the equipment required is readily available, and as you may have noticed, many of the techniques involved are strikingly similar to common reef-keeping techniques already being employed.
Terry discusses common types of filtration found in reef tanks.
Too often marine macro algae are only considered to be part of an aquarium's filtration system.
Evaluation of live food versus artificial food on the growth of juvenile Pocillopora damicornis cultured from planulae
The following is a report on the first experiment where Lee examined the effects of different foods on the growth of juvenile corals.
This article is a continuation describing some of the more philosophical filtration practices and concepts.
Based on technology developed by NASA, Spectrum Technologies markets a 'chlorophyll meter' - the FieldScout CM1000. This instrument is a simple point-and-shoot device.
In this month's column, Adam continues to discuss filtration and nutrient export.
In this month's column, our readers discuss how they control algae in their systems.
The author's viewpoint following this study is that mangrove plants may be useful to aquariums but in terms of nutrient uptake they are far inferior to macroalgae growth.
Why would I recommend dosing silica? Largely because creatures in our tanks use it, the concentrations in our tanks (at least in mine) are below natural levels, and the sponges, mollusks, and diatoms may not be getting enough to thrive.
I do believe, however, that the benefits outweigh the risks when one is growing macroalgae. To date there have been no claims of a demonstrated problem in a reef tank from reasonable iron additions.
