The only crabs that I consider to be truly reef safe are the commensal types such as the porcelain crab and coral crabs. The only reason such crabs can be considered reef safe is that they never leave their hosting spot.…

Submitted by Marc on Thu, 08/14/2014 - 4:07pm For over a year, I'd been using a small spiral compact fluorescent bulb that only cost $7, with an output that was 75w of 6500K lighting. Under this 'daylight' color, my macro algae grew steadily. While shopping at Home Depot, I came across a new sealed-floodlight bulb that caught my interest. This new bulb costs $10, and also uses 19w. The one thing the package didn't mention…

      POWERHEADS  -  Their most common use is to provide extra water movement within an aquarium. For Reef aquariums, this is vital since a great many of the corals need a good deal more water flow than what can usually be provided for by a sump's return line. A few powerheads located strategically will solve that problem. Due to their being easily moved, I find them to be a good choice since I can direct…

       While I believe these units are not so much of a needed item, they do have their use in providing a steady calcium supply to your aquarium.

       It was not long ago that a sump was merely a place to have a pump to send water to the main tank and to provide surface skimming by having an overflow system.

There are really only a few concerns when deciding upon your new aquarium, the material it is made from, its size, and to have it predrilled for reef equipment such as a sump. Material: You will have either a choice of glass or acrylic tanks, for tanks in the 200 gal and below range I would prefer glass, it is more durable, not as easily scratched. The only benefit I see to acrylic is in…

Presented by Charles & Linda RaabeMactan Island, The Philippines© 2008 All Rights Reserved   As great looking as some clams can be, they also seem to be a difficult species for new hobbyists to maintain.

Such water quality issues are also compounded by the fact that many hobbyists believe that the clams must be fed small particulate foods. That…

I'm based in Texas and have been in the hobby since 1998. In all that time, I've never used a chiller for my tanks. I prefer to keep the room temperature comfortable for me around the clock, and thus my aquariums have never gotten overheated. However, in the summer months it always helps to use cooling fans. They are economical, relatively silent and take up little space. The typical reason for a chiller is because…
