Giesemann Packs Robust Control Features Into New Matrix-II DIMTEC T5HO Fixtures

c296Matrix II DIMTEC Giesemann Packs Robust Control Features Into New Matrix II DIMTEC T5HO Fixtures Giesemann is one of the few companies out there that isn’t abandoning the tried and true T5HO technology, and in fact, they are still making groundbreaking strides that keep it totally relevant in a time dominated by LED light fixtures. Around a year ago, Giesemann revamped the look of their Matrixx T5HO fixtures to bring their aesthetics in line with their gorgeous Teszla and Futura LED products, and just a week ago they announced even more upgrades. The brand new Matrixx-II DIMTEC will share the same sleek look as its predecessor, but will also incorporate full Bluetooth connectivity that allows it to communicate with a variety of devices including personal computer, Macs, and Android powered devices. The user interface is provided by Giesemann’s own software package, which is very similar to the one used on the Futura LED system. The key selling features of the software include: Point to point multi-plot light cycle programming allowing smooth transitional lighting phases across an available 920 set points. Fully independent channel control over 2 – 4 channels dependent on light unit connected. Transitional color shift dependent on the mix of tubes across each channel. Fully adjustable cloud and weather simulations Fully adjustable lunar phases. Creation of dedicated user profiles MORE: Giesemann Packs Robust Control Features Into New Matrix-II DIMTEC T5HO Fixtures

Gems From Down Under

la sn 1024x680 Gems From Down Under
Australia is famous for more than kangaroos and awesome beaches.  Some of the most beautiful corals in the world also live there.  This unique Acropora originated from the Great Barrier Reef however the specimen has been grown to maturity in a captive aquarium in the U.S.  This was accomplished from a tiny seed fragment of the original colony that was imported.  The colony arrived in very rough condition with tissue necrosis advancing and my hopes for survival were slim.  I managed to fragment several small tips before the colony was lost and one half inch seed managed to survive.  Over a two year period the small fragment began to acclimate to the artificial reef it was placed into and grow rapidly.  The new colony began to show some amazing pigments as it matured and the pay off for the effort was realized.  Looking back at the original colony that was imported in my memory, and comparing it to the new captive grown coral, gives me a great sense of accomplishment.  Although corals come from all over the world to our aquariums, some of the most unique and colorful specimens come from down under.

Larval Rearing of the Purple Mask Angelfish

P.+venusta+d3+10913+40x+25C+photo+by+Karen+Brittain+jpg Larval Rearing of the Purple Mask Angelfish

Larval rearing trials began with the spawning of a Paracentropyge venusta pair in the summer of 2013. The first successful larval rearing trial started with a small spawn on November 13, 2013.  This was the fifth larval run with this species and the focus was on food density and consumption at different developmental phases.  The diet consisted of both cultured copepods and wild collected plankton with all food items being less than 100 microns in size.  To assess consumption rates, five random samples were taken for initial food counts at the start of each test period. All food items added to the larval tank during the test period were counted while maintaining a density of 1 to 2 food items per ml in the water column. At the end of the time period counts were again done to determine larval consumption. At this point a 75% water change was MORE:Larval Rearing of the Purple Mask Angelfish

A Brief History of the Saltwater Aquarium Hobby

blue devil 300x169 A Brief History of the Saltwater Aquarium HobbyOur hobby of keeping saltwater fish for the sole purpose of pleasure is not very old. People have been keeping fish for thousands of years, but virtually all of those fish were used as food. Asian cultures have been culturing carp and koi for enjoyment for centuries, but those are freshwater fish. Roots in Merry Old England Saltwater fish keeping for fun actually began in England about 200 years ago. At that time, wealthy Ladies had servants but lacked Oprah and soap operas, so they were bored and needed to find a hobby. England’s damp climate is conducive to fern growth, so the ladies would traipse through the bogs with their long hoop skirts and corsets on looking for ferns. They would then put the ferns in tanks that had glass fronts and wooden or slate sides. Then they’d sketch pictures of their ferns and mail them to their friends.

Coral Placement

center 1 1024x680 Coral Placement
Coral placement is as crucial to success with a captive coral reef as any parameter or piece of equiptment.  Mistakes can be made when building the reef that will inhibit growth and success as time passes and the specimens grow.  Placing Acropora corals in close proximity is safe in most instances as they do not have a strong mechanism to compete for space.  A soft coral or a stone coral such as Euphilia can however create a silent warfare that will inhibit growth and eventually cause death.  Often times as the corals grow and space becomes the limiting factor death will occur quite quickly.  The death can be misdiagnosed as one of the many other factors that are involved and add even more questions to the issue.  Experience with placement is a hard learned lesson and will undoubtedly confuse many.  Taking the time and patience to provide plenty of space when dealing with a mixed biotype style reef is essential for long term success.  A good rule to follow is to keep Acropora and Montipora species well away from soft corals and the large polyp stoney corals as this is where many of the issues occur.  Many of the Montipoas will get along nicely with Acropora specimens and that grown-in look can be realized if the time and dedication is provided.

Brownbarred Goby: Sand-Sifting Species Well Suited to Aquariums

brownbarred goby 300x169 Brownbarred Goby: Sand Sifting Species Well Suited to AquariumsMarine aquarists looking for a sand-sifting fish to keep the top layer of their sand bed stirred often run into a dilemma. Many of the species renowned for this behavior, such as the ever-popular and commonly offered yellowheaded sleeper goby (Valenciennea strigata), have the frustrating tendency of wiping out all the benthic invertebrates in the sand bed and then proceeding to starve to death because they don’t always learn to accept the non-living food items hobbyists offer. One of the notable exceptions to this phenomenon is the brownbarred goby (Amblygobius phalaena), a.k.a. the bullet goby or sleeper banded goby. A. phalaena does a great job of sifting sand, but it’s much more inclined to accept standard non-living aquarium fare than V. strigata and many other sand-sifting species are. Physical traits A. phalaena is typically goby-shaped with a robust body, high-set eyes, and a comically oversized mouth. More: Brownbarred Goby: Sand-Sifting Species Well Suited to Aquariums
