Fish Tank Filter

Excessive illumination (photoinhibition) has become a more prevalent problem in reef keeping with the increased popularity of aquarists trying to make molten lava in their aquariums via banks of 400-watt metal halides suspended over soft corals in less than 50cm of water. Such corals shocked by photoinhibition often pale in color ("bleaching" or expelling their pigmenting dinoflagellates and any remaining zooxanthellae shut down, effectively leaving the symbiotic host to starve to death. With a more tempered lighting scheme, various corals can be targeted for specific feeding to spur growth and reproduction in the absence of light far above

UV purification can be a very useful addition to an otherwise appropriate filtration system. Ideally a UV will reduce microbial levels to, or below those in the wild. Population explosions of these organisms are most prevalent in new, disturbed systems, and ones where bio-load/feeding is concentrated and vacillating. Hence the extensive us

With due consideration for the fact that mushroom/false-corals (corallimorphs) collected at 20 meters are less likely to thrive in the same aquarium next to a yellow leather coral (Sarcophyton elegans) collected in ankle deep water, one is faced with a challenge. We can either accept the fact that one or both will suffer for the unnatural mix under standardized lighting, or we can resist the temptation to mix them at all and separate them to species-specific displays. Unfortunately neither is likely. Most aquarists do not relish the former notion of a beautiful animal suffering and dying in their charge. Alas, most aquarists are also not likely to resist the temptation

Hi

I hope you like my pictures from last 19 years breading discus . In this time i work in Brasil to bread wild discus from amazonia . &l.

The Mad Reefer, Bloomington, Illinois
Does anyone know how to contact the owners of the Mad Reefer? I realized that it closed, but they have (had?) a fish tank of mine on consignment. I am looking to either reclaim the fish tank or see if it sold. Even if you just have the previous owners' names, that would be great. Thanks!.

anybody make there own frag plugs?
do i have to use concrete, or is there an easier way? is it something that can be done with sand and reef/crazy glue? or am i just off my rocker to think its that easy. i was going to use wax paper cones to make the mold. any help would be greatly appreciated..
