The new Tunze DOC Master skimmer models 9620/9640 offer improved ergonomics and efficiency. This new protein skimmer from Tunze, is an evolution over the traditional external skimmer designs, commonly used in reef aquariums. The Tunze Master DOC 9620 and 9640 protein skimmers are intended for use in applications where a high bioload is present, or where SPS is demanding of pristine water conditions. Simple installation, low-noise operation, a large skimmer cup, easy ozone integration, and a patented Anti-Overfoaming system are just a few of the features of this new protein skimmer from Tunze.

This Lettuce Sea Slug video from Morphologic Studios is one of our favorites. This colorful species is often mistakingly confused with a nudibranch. The Lettuce Sea Slug requires an ample amount of live rock on which it can forage for algae. Additionally, the Elysia crispata integrates chloroplasts from the algae into it’s own tissue, and therefore it obtains part of it’s energy from photosynthesis. This slug can easily get sucked into a powerhead, so please take care to cover pump intakes if you house one.

Lettuce sea slugs (Elysia crispata) are a commonly found in protected nearshore Floridian waters where green macroalgae proliferates. They belong to a clan of sea slugs, the sarcoglossans, that are characterized by their ‘sap-sucking’ feeding habits of algae. These slugs slowly patrol mangrove roots and rocks searching for green algae upon which they feed. They store some of the chloroplasts from eaten algae in their tissue, giving it the green coloration. The chloroplasts continue to function, providing the slug with photosynthetic energy. The ruffles along the back of the lettuce sea slug are called parapodia, and help provide more surface area for the chloroplasts to inhabit. They also camouflage the slug amongst the leafy algae that they live amongst. It is very easy to swim past a lettuce nudibranch without ever noticing it.

Don’t have enough flow? Well, the Tunze Turbelle Masterstream would do that job…… that is if you had a HUGE aquarium, Koi pond, or were running a Zoo or a Fish breeding operation. This new class of pumps from Tunze offers a high-capacity propeller designed for maximum efficiency, wide flow, and economical energy consumption. The new electronic Tunze PM motor operates at extra low voltage, and the pumps are quieter than ever, even at full force.

The smallest Tunze Masterstream model, the Turbelle Masterstream 6508, pumps out between 5283 to 21,133 gallons per hour, while the largest one (6515) shoots out between 13,208 and 39,528 GPH!!!!!!

A small sample calculation using Turbelle® masterstream 6515 (150 m³/h – 280 W) reveals that energy efficient water movement results in enormous cost effectiveness:
Tank volume: 60 m³, flow selection by centrifugal pump (32 m³/h – 2,200 W). At an annual operating time of 8,760 hours and a kilowatt price of EUR 0.20 this results in a cost saving of EUR 3,364 per annum !

The Turbelle® masterstream are electronically speed-controlled pumps operating on safety extra-low voltage of 12 V to 24 V. They can be used ideally for water circulation, wave action or wave-and-tide simulations. The models 6512 and 6515 come with Multicontroller 7096.

Model 6512 in 12 V technology and a flow rate of 110,000 l/h (29,058.9 USgal./h) has been designed especially for swimming pools or large aquariums.

All parts of the pumps are made of sustainable active microbicidal (SAM) polymers and polyoxymethylenes (POM); the motor axle is made of titanium alloy; the motor and the electronics are cast in polyurethane (PU) resin.

The pump control is integrated completely in the motor block ensuring a low-maintenance operation with high efficiency and ideal water cooling. All Turbelle® masterstream pumps only require one external power supply unit or safety connector with a corresponding direct current source (battery, solar cell, et cetera).

Fitted with Safety Connector 6515.50, Turbelle® masterstream can be operated on every 11 V to 24 V direct-current source (battery, solar cell). The safety connector permits normal operation with the TUNZE® power supply unit, but in case of a power failure it will automatically switch over to a car battery or a direct-current source.

I discovered Poly-Filter years ago when I was keeping fresh water aquariums. It was the miracle goto for pulling about anything out of the water. The makers, Poly-Bio-Marine states on their web site, “It is a formulation of a special patented material bonded to a synthetic matrix. By means of a unique proprietary process, the POLY-FILTER is made impervious to salt and is also organic loving to certain materials. It can absorb and adsorb contaminants and other toxic materials found in nature or added to fresh and salt water with or without fish and invertebrates.”

Saltwater? This got me wondering how it would do on my reef tank. Either through personal contemplation or through suggestions of others I came to the conclusion that Poly-Filter was just to good to use in a reef aquarium. A common fear is that the filter will work so well that it will pull the trace elements out of your water. Digging through their site I see extensive experiments have been done to ensure that Poly-Fiber will not pull trace elements from the water column. For the other ReefToolers that skate the fine line between geek and the unmentionable you may find the write ups on their site very informative.

Ok.. I’ll give you a small taste: Standard Specification for Substitute Ocean Water (ASTM) Standard D 1141 lists only six (6) trace elements which are : Barium (99.4 ug/L) , Manganese (34.0 ug/L) , Copper (30.8 ug/L),
Zinc (9.6ug/L) , Lead (6.6 ug/L) and Silver (0.49 ug/L).

More interesting reading can be found on Poly-Filter’s ability or lack of ability to absorb silicates, which can be found here:

Poly-filter is long known for pulling medications such as quinine sulphate, copper sulphate and formalin and Malachite green from systems after treatment. It also pulls out antibiotics. The Poly-Filter was developed to fill a specific need in the area of chemical filtration of aquarium water. One of the interesting aspects of Poly-Filter is the color changing properties that indicate what is being pulled from the water column. Through state-of-the art technical advancements in the patented hydrophilic materials and processes used to manufacture the Poly-Filter, unique performance characteristics have been proven in the application of the media to aquarium filtration.

These include the following:

1. No particulate release.
2. No leachable or extractable monomers, ions (anions, cations), binders, or cross-linking agents.
3. No desorption upon saturation.
4. Linear absorption/adsorption chemical filtration properties.
5. True color changes indicating filter function and replacement timing, i.e., blue – copper; red = iron; green = free copper ions; brown = normal organic loading; and black = heavy organic loading.
6. Effective removal (absorption/adsorption) of low molecular weight organics, volatile organics, high molecular weight organics, and ultra-high molecular weight organics.
7. Effective performance under adverse conditions such as water conditioners and slime coat restorers.
8. Removal of chelated and non-chelated metal complexes.
9. Guaranteed quality control by the actual media manufacturer (Poly-Bio-Marine)

The final say from a Poly-Filter fan: A very technical and thorough product! What’s in it for us hobbyists? Plenty! Poly-Filter Pad material, when used accordingly, removes ALL traces of copper treatment. Continued use of kalkwasser leave lead behind. Poly-Filter Pad material get-the-lead-out! Phosphates? Not a problem. The use of Poly-Filter Pad material in high-flow areas work like carbon, only better. All heavy metals are attracted to the woven matrix of polymer threads and are held there… no leaching back into the solution!

What are the downsides you ask? I don’t know of any.

After almost 2 years the National Institute of Oceanography (NIO) has successfully bread endangered yellow seahorses. In February 2010 the juvenile seahorses reached 1 year old marking the end of the NOI’s experiments and documenting success.

“Successful life cycle experiments of yellow seahorse will help to facilitate the development of small scale aquaculture farms by seahorse fisherman, as a viable alternative to capturing wild seahorses”‘, scientists at NOI state.

The NOI web site states the Hippocampus kusa (bleeker, 1852) is found in the tropical Indo-Pacific. Their native habitat typically consist of shallow, shoreline waters with mangroves, sea grasses and other plant life. The yellow seahorses are currently traded in 77 countries for Chinese medicine as well as the more obvious fish industry. It is estimated that 25 million seahorses are traded annually.
