BIO-ACTIF system is a new synthetic salt from Tropic Marin, designed to promote the growth of bioactive substances and improving livestock health by promoting protection for the mucous membrane of reef aquarium fish. BIO-ACTIF is also said to promote brighter colors and improved polyp extension in corals. In addition to these benefits, BIO-ACTIF is supposed to improve the breakdown of excess nutrients and pollutants in the water column. This in turn leads to clean and clear water. In order to maximize this process, a 15% water change is recommended by Tropic Marin.

Here is a detailed list of benefits of the BIO-ACTIF reef salt mis from Tropic Marin:

  • Rapid success in coral growth, even for beginners.
  • Advanced reef aquarists can grow even very challenging and delicate species which have always been regarded as impossible to keep.
  • Corals which once seemed incompatible because of their different demands in terms of care can be cared for together, with all species enjoying good growth and ideal conditions. Small polyp and large polyp stony corals can be kept together with leather corals, for example, without their combined care being detrimental to either group.
  • The low-nutrient environment also allows sponges and complex higher-order algae to grow without running wild, adding their own natural and authentic touch to the indoor reef.
  • Active control of the pH and carbonate hardness is conducive to the sustained growth of corals, calcareous red algae and other calcifying organisms.
  • Skimming action for the elimination of contaminants and suspended matter provides a permanent solution to cloudiness, allowing the reef aquarium to shine in full clarity in the most vibrant colours.

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.

The intent of this article is to document the cycling period of a sulphur denitrator using digital read outs using a Pinpoint nitrate monitor. A simple, 60 gallon FOWL system was set up using only live rock and a maxi mod. The nitrates were allowed to climb to 29ppm.

Here is a photograph of the tank showing the denitrator on the right side.

alt

The initial reading of the nitrates in the aquarium was 29 ppm. When using the the suggested API test kit the color indicated being somewhere between 20 to 40 ppm. The Pinpoint nitrate monitor showed 29 ppm.

alt

0 days 01 hours

The sulphur denitrator ran for 1 hour with the effluent valve wide open to allow the water to circulate through the unit. The effluent water then tested to be 25 ppm. This documents an immediate 4 ppm decrease in the first hour. alt

Here is a picture showing the denitrator effluent.

alt

After running for one hour wide open, the effluent was set as slow as i could get it. Roughly 40-60 drips a minute.

0 days 02 hours

A test of the effluent 2 hours into the cycling shows an immediate drop of 2 ppm.

alt

0 days 03 hours

A test of the effluent 3 hours into the cycling shows a remarkable drop of 7 ppm. As seen below the effluent is now testing 16 ppm.

alt

0 days 04 hours

A test of the effluent 4 hours into the cycling shows no decrease in nitrates from the effluent.

0 days 05 hours

At the 5th hour the effluent test to be 12 ppm. That is a 17 ppm drop in the effluent in as little as 5 hours.

alt

0 days 06 hours

A test of the effluent 6 hours into the cycling shows the effluent creeping back up to 16. The increase is normal and indicates that the drip rate will need to be raised shortly.

alt

A test on the tank water shows the nitrates have dropped from 29 ppm to 24 ppm.
alt

0 days 16 hours

Overnight the nitrates rose to 18 ppm. The drip rate will now be double to 80 drops a min.

alt

0 days 17 hours

The effluent was tested again, 1 hour after the flow rate was increased (doubled). The nitrates are back up to 22 ppm.

alt

The tank water was also tested after the effluent was doubled to 80 drips a minute showing the nitrates have climbed to 26 ppm. This seems to be working backwards, since the nitrates have climbed. This is part of the cycling procedure.

alt

0 days 20 hours

A test 3 hours later showed the same readings.

1 days 3 hours

A test 7 hours later shows the nitrates in the effluent rose by 1 ppm to 23 ppm.

1 days 7 hours

A test 4 hours later shows the effluent starting to drop again to 20 ppm.

alt

1 days 17 hours

Test show 10 hours later the effleunt has dropped to 10 ppm. The tank water was again tested showing the nitrates to be at 23 ppm.

alt

2 days 8 hours

15 hours later the shows Lo on the Pinpoint nitrate monitor.

alt

Now that the Pinpoint monitor is reading Lo it is time to recalibrate the monitor to the low side so that we can get accurate readings.

The drip rate was increased to 100 drips a minute while the Pinpoint monitor was being calibrated. After calibration the nitrate reading was 10 ppm.

At this time the effluent was again raised to 120 drips per min.

2 days 7 hours

Effluent test show the nitrate level to be 2ppm.

alt

2 days 7 hours

The effluent was increased to a “weak” stream.

2 days 14 hours

Test on the effluent show the nitrate level is now untestable by the Pinpoint monitor.

alt

Test on the tank water also show the nitrate level to be untestable.
alt

Now that the tank has been reduced to virtually no nitrates the effluent will be increased to a regular stream as the filter will need to turn over more water. If the effluent is not increased enough a rotten egg smell will be noticed. If this is experienced, simply increase the flow slightly.

This cool Flatworms High Definition video from Morphologic Studios, shown at 3x the actual speed, depicts to movement and behavior of these “cute” little things. Also known as Red planaria, this common pest will rapidly grow in numbers in tanks with elevated nutrient levels. At high population levels, red planaria can cover corals and block the light from reaching them. Where’s a Blue Velvet Nudibranch when you need one? 😉

The flatworms (Convolutriloba retrogemma) featured in the video are shown at 3x normal speed. They each range from 2-4mm in total length.

These particular flatworms harbor symbiotic zooxanthellae in their thin tissue and utilize the excess sugars they create as their primary energy source. Packets of zooxanthellae can be seen as the tiny, red-brown dots along the back of flatworm. Their reliance upon this photosynthesis requires that these flatworms bask in sunlight like little photovoltaic cells, and enables them to live without a developed digestive system.
