A Publication of the DFWMAS        March 2005


Saturday, March 26, 2005

On a cold and rainy Saturday, 75 hobbyists braved the weather to attend the conference. Four speakers eagerly anticipated sharing their knowledge, while the club's Board of Directors focused on making sure the day would progress in a timely fashion. Below are some images that will hopefully allow you to capture what Next Wave is all about.

 

Once everyone was checked in and seated, we were ready to begin the conference. Anthony Patrick, Vice President of DFWMAS, introduced each speaker and kept us on schedule.

 

Bill Werner, the club's Audio/Visual coordinator, made sure we could see and hear every moment. Between speakers and during lunch, images from the reefs as well as other information were provided on large screens bracketing the stage.

Steve Tyree's talk discussed the needs of SPS corals. Image after image, he helped identify these corals, providing excellent advice on the placement of these challenging species that many desire to keep in their reef tanks.

After providing insight about some of the problems many have encountered, Steve quickly shifted gears and provided a brief demonstration of how he chooses to frag SPS colonies. His focus on the safety of the hobbyist as well as the coral was easy to realize. One suggestion he made was to frag corals from below when possible, and avoid cutting the live tissue. When fragging a thick Montipora capricornis, cut from below with a dremel tool, but not all the way through. Once it is very close, stop and use a flathead screwdriver to wedge and snap the frag off.  Great suggestion!


Steve brought along a couple of his books as well as a number of CDs, VCDs and DVDs for those that wanted to get more information on Corals, Zonal Filtration, or Sponges.

Allen Heath, seated to the right of Anthony, was busy selling raffle tickets during every break. Allen is our club's treasurer, and does a great job keep track of our finances.

 

 

 

 

 


Next was Dr Sanjay Joshi , and his focus was on the topic of lighting which was eagerly anticipated. His research of Metal Halide usage was in depth, and questions posed by the hobbyists were well answered. Reflectors, ballasts and bulbs are integral to what we hope to keep in our reef tanks. Sanjay's counsel wasn't necessarily to always spend more money on high end products nor replace bulbs more often. Rather, we should consider PAR (intensity), as that drops off as the bulb ages. Does spectrum (the colors we select for our lighting) shift over time? Apparently this is a myth according to his extensive tests. PAR decreases, and that should be the reason we replace the bulbs.


Some decided to take notes. For more information, Sanjay gave us this URL.

 



"That alone was  worth the $35
    entry fee!"


-- a comment (referring to the morning session) made by one of the attendees as we broke for lunch.

By lunchtime, Coburn's Catering already had tables set up and waiting for the attendees to line up. Hamburgers and hot dogs were available, as well as a vegetable lasagna for those that prefer vegan fare. Also provided were potato salad, beans, chips, canned soft drinks, & cookies. Coffee was available all day long, but the Irving Bible Church had a Starbucks right down the hallway for those that needed that specially flavored beverage.

After lunch, everyone quickly took their seats for the next presentation.


Daphne Fautin's choice of jewelry was a visual indicator that we were in for a treat.


Her talk was animated, literally! She focused on Pixar's Finding Nemo to educate everyone about what could happen and what was not likely to occur when it came to the story about Nemo and his dad. Daphne is a marine biologist and clearly states that she is not an aquarist; thus her research is based only on what can be found in the ocean. Her knowledge about anemones and anemonefish was a great benefit to those seated in the audience.


Larry Jackson, who resides in San Angelo Texas, was our final speaker of the day. His quiet demeanor and dry wit caused everyone to take note of what he was saying (and what he didn't quite say), so as not to miss a beat. During his slide show, he'd pause when necessary to relate some event which resulted in laughter by the audience. "Next slide...please," was almost a joke in itself. David Washington (above right) recorded the sessions with a Sony digital video camera, one so new that it isn't even on the market yet!

The following images were taken by Larry last year while diving in the Great Barrier Reef during spawning season.





Raffle Time!

Oceanic donated a 58g aquarium.

Oceans Motions donated a Super Squirt and two revolutions, as well as a Mag Float razor Scraper™

Premium Aquatics
donated three $25 gift certificates

Champion Lighting
donated a Blueline LED moonlight and a Tsunami Auto Topoff device

Jeff's Exotic Fish
donated two $25 gift certificates

Drs Foster and Smith
donated a $25 gift certificate

Brine Shrimp Direct
donated a variety of foods. As these were not shipped in time for Next Wave, those prizes were shipped right to the 13 winners' front door.

We want to thank all these vendors for the generous donations!!!

Other prizes included the DFWMAS calendar (lots of winners), three sets of the MACNA XIV DVDs (13 disks per set), a GFCI outlet and even 80 lbs of aragonite-based sand!

Because the raffle contained livestock that had to be on display all day long, leaving it bagged was not an option. Not to mention that it arrived by plane on Friday around noon, and the prizes weren't going to be awarded until 4 p.m. Saturday afternoon. Thus, we needed a display tank and Marc Levenson decided to make one. The tank is 34" x 24.5" x 8" and lit with a 250w SE 13,000K MH powered by a IceCap Electronic Ballast. The simple reflector was probably frowned upon by Dr Sanjay Joshi. ;) To avoid heat issues as well as to avoid blinding the attendees while seated, the canopy was built with a 12" tall enclosure, and mounted on acrylic legs over the tank.


A spray bar was used to provide circulation, but two MaxiJet powerheads really made the difference.


A corner was sectioned off to act like an overflow. This kept the surface clean of any floating debris.


The spraybar had a simple connection at the end to act like a foot. This was a simple stabilizer.


A peek at the lighting.


Access was easy in this 25g frag tank, and with the pumps turned off, livestock was viewable from above.

 
Here is a good example of using the white balance setting with a digital camera. To the eye, everything had quite a blue hue to it. Once the camera's white balance was set, the corals photographed far better. Below is a larger image of the picture on the right.




Two Gigas clams of the six in the raffle. Each was about 3" in size.




 
17 SPS (Small Stony Polyped) Corals were awarded, plus a few frags donated by one member.

 
 








Nine zoanthid rocks were awarded as well, which was good for those that don't keep SPS currently.

DFWMAS thanks the Irving Bible Church for their generosity by providing us the perfect room for our conference.

 

A Review:

For those who might have been considering attending - it was great!

There were 4 very good speakers, all well-renowned in the field. Each had very good presentations full of years of learning and experience.

Steve Tyree started the day with a discussion of the needs and various methods of care of SPS, including a fragging demonstration. He's an enthusiastic and energetic person, and his talk was very good.

Next up was Dr. Sanjay Joshi discussing lighting and MH in particular. This was the most useful for me right now - his talk really demystified the topic of lights, ballasts and reflectors.

Dr. Daphne Fautin spoke on anemone and their symbiants - this was great. Dr. Fautin is a marine biologist who does not keep tanks. It was a fascinating discussion of anemone and clown fish in the wild, with lots interactive discussion with the audience re: experience in aquaria.

The last presenter was Larry Jackson with a slide presentation of one of his many visits to the Great Barrier Reef. Larry is a phenomenal photographers and his knowlege of the subject is very deep. That combined with his speaking skills, story telling abilities and a superb dry wit made this a great wrap on the presentations.

The logistics were well managed, lunch was good and included a nice vegetarian offering. The layout was great; between that and the very professional audio visual support - there wasn't a bad seat in the house.

And lastly, the raffle was unbelievable!! There was a tank full of beautiful SPS, frags and colonies, as well as some very nice zoanthid colonies. The dry goods were abundant, inlcuding a nice tank from Oceanic.

The DFWMAS board worked hard to keep this event affordable for all, at $45 for non-members and $35 for members, it just couldn't be beat! It was a great investment of both time and money for the attendees.

In summary, it was fantastic... don't miss the next one! - Dawn B. of Dallas

 

Things I learned:

1. I never knew that clownfish protect the anemone from predators in nature.
2. I didn't realize that a better reflector can allow the hobbyist to use a lower wattage bulb and get the same results.

1. MH lights don't shift spectrum at all. They only lose intensity.
2. To preserve the natural reef, we should only keep anemones that reproduce asexually (i.e. tank raised)
3. To maintain your flow, run food grade acid solution through your return plumping for an hour or so. This clears out all calcium build     up. Larry had very good description on this.
4. If you want good customer service, don't go to the all-diving trip in Australia like Larry did

1. Which corals can can go where - upper, mid, or low in the tank - based on flow and lighting.
2. Don't glue the coral, especially porous ones - glue the rock it is going on, and use water to make it "stick" better.
3. Don't cut a coral all the way through, and especially not live tissue. (Use the cutters to finish the job.)
4. Sanjay has a website for great info. You can compare light bulb brands, reflectors, etc. And he mentioned that XM brand was     better than Ushio - which is funny, because I switched to XM a few months ago - I did a smart thing.
5. Oh, last thing! I have a weird clown, that will host in anything soft. This is not normal behavior - LOL.

1. I was changing my lights after 9 months. Now I will lower them from 12 to 6 inches and get another 9 months out of them.
2. When I do get new bulbs I can confidently buy the less expensive brand.

1. Meeting fellow members and having discussions over the topics presented by the speakers.
2. That according to Sanjay, actinic supplementation is not necessary with 10,000k, and especially 20,000k bulbs.

1. You can maintain an anemone without much or any supplemental feeding.
2. The use of Sanjay's lamp database will be invaluable in picking my next lamp.

1. The speakers, while all highly intelligent persons, were able to present thier topics for a complete wide range from novice to     advanced. This is the part I was worried about. They were able to make me understand without having to resort to drawing stick     figures!
2. I had no idea anenomes were so long lived in the wild.
3. The size of a clown fish is no indication of age or food availability.

1. MHs don't seem to shift spectrum only intensity over time. I think this could be huge if we come up with some easy ways to raise     and lower the bulbs we cold drastically extend the life.
2. Clownfish can protect anemones to some extent. I knew that anemones always had clownfish in the wild but never knew that little     clown helps keep big butterflies away (at least sometimes)
3. Sanjay's database should be super useful now that I have a better understaning of what all that stuff means!
4. The union to clean pipes Larry uses is a great idea! I had heard that before from him but it is brilliantly simple!

1. Clown fish size is not due to age- it has to wait for another clown to leave for it to grow. And then a small one comes in behind to     complete the cycle.

1. To check your water clarity, siphon off about 5 gal. of water into a white bucket. Light blue=good green=ok yellow=bad.
2. The size of a clutch of Clown fish eggs is around 300-400. (WOW!)
