Review: Tunze Turbelle 6105 stream pump

Coming from an operation as highly-regarded as Tunze, one would expect the 6105 to be ‘fit for purpose’. After all at a RRP of around £240 this certainly isn’t the cheapest stream pump by any means. The incorporation of a number of innovative technical solutions such as plastic bearings, micro-processor controlled motor, silicone absorbers and titanium alloy axle all look great on paper – but how does it perform in the real world?  Continue reading Review: Tunze Turbelle 6105 stream pump

Baby Ray Is Christmas Surprise For UK Aquarium

image: Digital-Reefs stockOne of only a handful of institutions in the UK holding this species, Torquay’s Living Coasts was recently blessed with its very own ‘christmas miracle’ in which a female ‘pup’ bluespotted ribbontail ray was born at the facility.

Found throughout the tropical Indian and western Pacific Oceans, Taeniura lymma are often observed on coral reefs where they can grow to around 35cm (14 inches) across. Continue reading Baby Ray Is Christmas Surprise For UK Aquarium

Review: Little Ocean Filter Sock Holder

New Species: Arrowhead Soapfish

A new species image and profile has been added to the Digital-Reefs galleries. The Arrowhead Soapfish is quite unusual in the trade and, with its beautiful green-blue colouration, it’s no surprise that this specimen caught our attention during a recent shoot at a marine retail outlet. Part of the large Serranid family of Groupers and Sea Basses, the Soapfish are remarkable in that they exude Grammistin (a toxic, bitter-tasting skin secretion) when handled. As well as giving them their common name, this strategy provides them with an effective deterrent from predators in their natural environment.

Review: Hanna Calcium Checker

With natural seawater containing around 420ppm, Calcium is both a major ion and a critical building block for a myriad of calcifying organisms in the oceans. These organisms range from colourful reef-building SPS corals, to tiny molluscs, to a whole host of other life-forms. Along with Alkalinity and Magnesium (to which it is intrinsically linked) Calcium should therefore be carefully monitored and controlled in a reef system. If levels fall out of balance the organisms that rely on it are likely to be adversely affected. Continue reading Review: Hanna Calcium Checker

Video: Soft Coral Propagation Showcased

SPS and LPS corals seem to get all the limelight sometimes, with their often intense colouration proving to be immediately enchanting. Don’t foget soft corals though because, as shown in this lovely video from Tidal Gardens, certain species can rival their more rigid cousins. In terms of form and movement, softies can make for a stunning display plus, many soft coral species can be hardier, and can sometimes be kept with fishes that are partial to the taste of other corals.

Coral Cores Reveal Secrets Of El Nino

By examining a set of fossil corals that are as much as 7,000 years old, scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation, a Pacific Ocean climate cycle that affects climate worldwide.

Showing that 20th century ENSO climate cycles are significantly stronger than ENSO variations captured in the fossil corals the new coral data nevertheless reveals large natural variations in past ENSO strength, making it difficult to attribute the 20th century intensification of ENSO to rising carbon dioxide levels.

By analyzing the ratio of specific oxygen isotopes in the coral skeletons, the scientists obtained information about ENSO-related temperature and rainfall variations during the periods of time in which the corals grew. The isotope ratio of the coral skeleton changes with the temperature and amount of rainfall, providing detailed information about environmental conditions during each period of the coral’s growth.

Using the new sequences to quantify the range of natural variability in ENSO strength, the researchers have detected a modest, but statistically-significant increase in 20th century ENSO strength that may be related to climate change.

New Reef Care Program Provides Ideal Solutions For Nano-aquariums

Red Sea is pleased to announce the launch of some of its most popular Reef Care Program (RCP) supplements in smaller sizes, in response to overwhelming consumer demand from hobbyists with nano-aquariums.

Based on original scientific research carried out by Red Sea’s scientists, the RCP is divided into 4 distinct sub-programs; each addressing key issues affecting the health, color and vitality of corals within aquaria. Continue reading New Reef Care Program Provides Ideal Solutions For Nano-aquariums
