Vandals Shoot Up Aquarium Store

When you think of potentials problems you could run into owning an aquarium store, a shoot out probably doesn’t rank high on the list. Unfortunately, for the West Texas ‘Mr. Aquarium’, they have had to add it to the list after this weekend. Saturday early morning thieves broke into the back door of the aquarium, where they then fired 10 shots into the tanks, spilling over 1,000 gallons of water.   MORE

Potassium is an Element That Needs a Second Look – Part 3

Pipe Organ coral seems to benefit from potassium dosing, like its Octocoral brethren, Xenia.

Pipe Organ coral seems to benefit from potassium dosing, like its Octocoral brethren, Xenia.

 Those looking to dose potassium should do so carefully and slowly. Overdosing potassium can be lethal to the coral. There are several kits on the market and some of them can tell you if potassium is below 400 ppm. If it is, you will generally want to correct this. It can be very hard to grow certain coral in low potassium. Most commercial salts create a mix that is near 400 ppm. Marine aquariums should be maintained at least around 400ppm. I have been running certain systems higher, 600-800+ ppm. If you can’t find a test kit that meets your needs, you can use a company where you send in your water for testing, they have higher range potassium testing capabilities. MORE

My, How Your Colors Have Changed

We’ve all heard of corals morphing under different lighting. That piece that looks great in your buddy’s tank looks dull and washed out in yours. Or, you get that coral that does a complete 180. You see it at the store and it looks good, but once established in your aquarium, it turns into a gem. Well, we as a community do talk about coral color changes quite a bit, and we think we have found one of the most extreme examples of such an event MORE: My, How Your Colors Have Changed

Blast Of Color

pb macro
Some corals, like the Acropora desalwii above, really add a blast of color to a reef aquarium.  This image was taken from the top of the coral, and shows the parts of the specimen that are exposed to the brightest light.  The contrasting colors and striking pigments are most visible from this angle, and the lower branches and the shaded areas are typically less colorful.   Its common name is Pearlberry because of its pearlescent and berry colored pigments, and it was grown from a seed fragment over several years.  This is one of the most colorful staghorn corals found in the hobby and can grow rapidly in captivity.  When ORA aqua farms first released it (several years ago) it was common and readily available, but high demand for this specimen has made it harder to find, though many smaller propagator and micro growers have seed fragments available. This coral seems to prefer bright light and has the brightest pigments in a lower nutrient aquarium; high phosphate tends to rob the beautiful colors from it but the Pearlberry is hardy and will grow in a wide range of aquarium bio types.  Keep Alkalinity, Calcium and Magnesium in range to help keep the colors at their best.  Adding a Pearlberry to the aquarium will certainly add an exciting blast of color! is the world's leading destination for sustainable coral reef farming and the aquarium hobby.
