Diver's Den Tour- Invertebrate Section

To continue the previous thread, this post will feature the invertebrate section of the facility.
First I want to show you the massive protein skimmer and reactor combo at this LiveAquaria, there are several of them:
protein skimmer + reactor
This protein skimmer is taller than me... enough said.
carpet anemone
Asked my wife to model for scale, humongous carpet anemones
carpet anemone
More carpet anemones
Each of the anemones in this section, including carpet and a bunch of bubble tip are all hosting a pair of clownfish. it's really cool to see they make them all happy, even though as a retailer it's completely unnecessary to pair clownfish with anemone since one or the other would be sold soon anyways. But they did what they can to make each feel happy.
long tentacle anemone
A bundle of long tentacle anemone
derasa clam maxima clam
 a cluster of derasa clams (not yet offered on diver's den, they were exclusive for the tour), and a bunch of cultured maxima clam. very sweet deals! I managed to snatch two of these handsome derasa clams
Lighting may be one of the biggest questions any hobbyist buying from LiveAquaria wishes to ask. In the photo below you will see a broader view of the facility with lights running on a track. The lights run in a lateral movement so that it can cover all angles of the photosynthetic animals beneath rather than creating a "hot spot". When I toured this place a few years ago all lights were 400W 20K Metal Halide. Today this facility has a mix of high end LED (such as AI hydra + a few other varieties). All holding raceway are no more than 12" deep. All the animals look healthy and for clams I can observe significant growth indicating excellent health condition.

The livestock raceway
Here is a picture of the holding section for shrimp, small crabs (such as acropora crabs) and small shrimp (pistol shrimp or squat lobster, which by the way are size of a pinky nail!) They are held in individual transparent containers approx. the size of a film box (if you are born after the mid 90's you might not know what that is lol).
squat lobster
squat lobster, I can't believe how tiny they actually are compare to the online photos.
maxima clam diver's den
maxima clams in the diver's den section
And lastly, the diver's den clam section. I must say, almost all the clams in this section appears much larger than what is seems on the photo (contrary to the squat lobster), and honestly, the photos don't do justice on how beautiful they are. One of these clams I purchased looks like a mustard, brown color online but turns out to be a shiny gold in person! All of them are kept under 400W metal halide, 20K bulbs hence the very blue photo here. And one thing they offer that no one else do is live arrival ad 14 day guarantee.
Here is a couple videos:

20141124 180 Gallon Reef Ready Tank Build Part 3

I spent day 1 of my vacation in the garage building the canopy frame. This was made of .5X2 and .5X1 wood. All I have to say is it's not easy doing the whole thing with one person and sub-par tools
180 Gallon Reef Ready canopy
The frame fits well over the tank. I plan to hang 3X 150W LED lights.

New freshwater light

My previous light on the Freshwater 46 Bowfront was a Marineland double bright LED system for about two years. The light actually ended its life sooner than I thought it should. The light began flickering and died. So this time I purchased Current USA LED light. The review is still out. I shall report back in a month or two:

2014-05-16 Species Spotlight- Derasa

This is the third Derasa clam I've kept in my personal aquarium.
My first clam came as a birthday present, a 5" derasa, had the tiger spotted marking.
Second one is similar to the one below, also a 5" derasa, with a slightly lighter color. That one unfortunately died due to disease introduced by another clam.
The current clam I have is between 8-9" and has beautiful stripes down its mantle.
In many people's opinion, Derasa clam is one of the hardiest, and easiest clams to keep.
In my opinion, squamosa is the hardiest and easiest, but Derasa clam is a close second.
Like all clams, it does require full reef water condition with extra care in calcium level for proper growth. It will also need slightly nutrient rich water (i.e. plenty of fish waste) to thrive as it absorbs phosphorous from water to build its body parts. Hence it's nearly impossible to keep clams in an aquarium with no fish in it.
Although Derasa doesn't require as much intensity in light as Maxima and Crocea do, it still need a decent light source. I've been able to keep it healthy under power compact at at least 5W/gallon with slower growth. Currently I have it under my AI sol blue LED fixture at around 70% at peak time and it's growing rapidly. Many others keep it under Metal Halide, which is more than enough light but can really suck up your energy bill.
Unlike Maxima and Crocea, you should place this clam on a sand bed. And give it plenty of room to "rotate" as it has a mind of its own in choosing what direction it wants to face. Lastly, keep the tank free of potential clam eaters. I had a flame angel who would nip at my Squamosa before. That flame took its own life one day, and my flame angel II has been very well fed and has not touched the clam.
One other conscience complier is that most of these clams you find in the trade are now aquacultures with minimum to none impact to the reef. And the bonus of aquacultured livestock is they are far hardier than those wild collected.

2014-05-08 Save $$$ on electricity

I have heard and seen many discussions on how much energy their reef tanks draw and that they can see a BIG difference in energy bill with/without the tank operating. Today I want to make an attempt to break it down by using my own tank as an analysis.
First of all let's understand how do power companies charge your energy usage
Below is an example of one of my recent bills:
  Customer Charge                  30 DAYS   AT $    .34308  $       10.29       
  State Low-Income Asst Fee        30 DAYS   AT $    .10333  $        3.10       
  Distribution Service           1356 KWH    AT $    .03000  $       40.68       
  Electricity Service            1356 KWH    AT $    .10992  $      149.05       
    Subtotal Electric Meter     250177 ---------------------------$      203.12  

Note the items in line 1 and 2 are things you cannot change- you are paying those regardless how much energy you use.
And line 3 and 4 are basically two of the same thing, so I am going to add it together and call it approximately $.14 for each KWH of energy we use in the house.

KWH stands for Kilowatt hour. Basically if you add up all the wattage your household electronics' and appliances' labels you are looking at this. To illustrate:
1356/ 30 days= roughly 45 KWH for each of the 30 days this month, meaning I use 45KWH each day. To divide that by 24 hours, I am using nearly 2KWH each hour. 2KWH= 2000W= 20 X 100W lightbulbs on simultaneously for the entire 24 hour cycle each day. Using this principle above, let's estimate what % of my household energy contributes to my tank:

Tank energy:
Light: 2X70W Aqua Illumination Sol Blue LED on for 10 hours at an average of 35% of the 70W= 70 X 2 X 35% X 10= 526W
Heater: 200W, but not on constantly, probably on for approximately 70% of the time- 200 X 70% X 24= 3360W
Return Pump: Mag drive 7- 60W X 24hours= 1440W
Powerhead/wave makers: 3X 15W X 24hours= 1080W
Skimmer Pump: 60W X 23 Hours (minus feeding time)=1380
Total= 7786W

Here is the kick, even though electronics may label as 100W. Few to none ever operate at exactly that amount. Most of them actually consumes 20-40% more energy to operate at the energy level labelled. In another words, if a light build is labeled 100W, it might actually consume 140W in reality. 

For that reason, we will multiply 7786 X 140%= 10900W
10900W=10.9Kilowatt, let's call it 11 KWh
So each day out of the 45 KWh, 11 goes to the tank, roughly a quarter of my household energy! and if you look at my monthly charge- that's about $50

Now, things actually used to be worse- Metal Halide bulbs. I used to use a fixture containing 1X250W Metal halide + 4X24W T-5 tubes, a whopping 342W. And this fixture did not have the ramping and % control like the LED lights do. So if I have this light on for 10 hours/day- 342X10= 3420W 
Add this up with other parts (heater, pumps, skimmer)-10680 X 140%= 14952W
14952W is roughly 15KWh

So let's do the math: 15KWh - 11KWh=4KWh/day
4KWh X 30= 120KWh/month X $.14= roughly $17 a month of energy bill difference.- $200 a year in energy savings!
A Good LED lighting system cost between $400-$900 and lasts 10,000 hours - if you can keep the light for more than 2 years you got your money back.
A Good Metal Halide system cost about the same amount and definitely does not last as long - at least you need to replace the $50 bulb annually for optimum performance.
So next time if your significant other questions why you need to upgrade to the LED and other energy efficient pieces, please show her this post and tell her- you are saving money on the energy bill in the long run.

2014-05-05 Keeping Clams under LED

I just curious to see what other reefers are saying about the LED light's effect on keeping giant clams. So I did some research:
I've went through a few different forums but found that these two have the most constructive answers I was looking for. 
In general, the answer is yes. But it depends on how the light was made (home made, cheaply made in China, etc), the total wattage of the light, distance of light from water, distance of clam from water surface etc.

I can definitely attest that clams not only survive, but thrive under LED.
I have had my aqua illumination sol blue for more than 6 months now. And I've kept my three big clams in there for almost 5 months. I programmed my light to mimic the natural sunlight intensity bell curve throughout the day with the highest being 3pm at about 85% and down to 15% at beginning and ending of the day. The largest of the three squamosa grew 2", from 7" to 9", the derasa is a bit more sensitive to fish swim by so grew a bit slower, about 1.5", from 6 to 7.5". The smallest of the three is also a squamosa, grew from 5" to about 7" now. My calcium level was around 500 before these clams were in. And now I am struggling to keep it over 350 when they grow this fast! My tank is 92 Corner and they are all sitting at the very bottom. So yes, you can definitely keep clams happy with LED lights.

2014-05-01 Livestock Spotlight

My heart almost stopped when I saw this clam...
Yes, I have a thing for clam. In fact it was when I laid my eyes on the giant clams in display in Waikiki aquarium that made me fell in love with this hobby.
http://www.pacificeastaquaculture.com
maxima clam
maxima clam as seen on Pacific East Aquaculture
This is a 5" Tahitian Maxima clam with golden turquoise leopard spotted mantle.
To keep this claim, please have nothing short of Metal Halide (at least 250W, 400W preferred) or LED. You will also need adequate calcium level (400+), 8.3pH, and slightly dirty water (nutrient rich) so the clam can feed on the nitrate and phosphate in it.
Believe me, if I have room in my tank I would have snatched this up in a heartbeat!
But at the moment my tank is a bit crowded with an 8"Squamosa, 8"Derasa, and 7"Squamosa...
and are all growing rapidly.

Temporary frag tank

I am sick of fragging corals and just parking them in my display tank!
So i went to the store and got some ceiling grill to make my make-shift temporary frag shelf in my sump.
First I spent an hour clean out my sump and scrubbed everything clean. Then I cut the grill to fit the tank. I then drilled four small holes on the plastic top and hang the grill using fishing lines.
At the moment I dont have too many frags but will be expecting quite a bunch in the near future. I am placing some of the low-maintenance frags here such as some shrooms and leather. The lighting for my sump is a reef ready marineland LED

Neon green birdnest ORA

ORA is one of the more reputable marine aquaculture companies that provide a broad variety of corals, fish, and inverts. I strongly recommend ordering and purchasing their product as they practice responsible breeding and marineculture to reduce the stress of overfishing. This is an ORA neon green birdnest I picked up a few weeks back in the LAS ( local aquarium store) it glows with neon green under the 420nm actinic and magenta LED lighting
