Here is my 550 just over 6 years old. It has become rather overgrown and the tank needs to be replaced but there is always the matter of funds. I just hope it stays together until I can replace it :rolleyes:

very impressive. I agree with you; you need a new tank -- a biggggger tank. :D

I know why you want a new tank, same reason why I want a new one and I haven't even gotten it together, this damn hobby is an addictive bank breaker that sucks your dry and spits you out and always wants you wanting bigger and better, alright that sounds wrong but you get the point.

Very nice tank, hardly ever get the chance to see a 6yrs matured reef tank here on RC. Any tips you want to pass on to use big tank newbies that you have learned after this time of keeping that beast?

btw love the trigger, beautiful fish.

What are you thinking for your next tank's size and dimensions?

Beautiful. I hope my tank looks just as good in a few years. I have a couple questions.

1. What type of substrate? DSB? BB?
2. What type of fish is the Angel with the blue mouth and yellow mask on the eyes. That's a beautiful fish. I thought Angels were considered not reef safe, but it looks like yours turned out just fine!

Hello,
The problem with the tank is that the seams are falling apart :mad: A few years a go Zephrant came over and resealed about 6' of the top where it meets the back and added a patch on the top where one of the braces had a crack in the corner. Now all the top seams where halide light can hit are cracking and crazing. I have a 2x4 along the front and back top squeezed together with 4 - 5' long bar clamps. Without them the back panel bows about 3/4" past the top plate :eek1: .

I really wanted to replace it with a 120"Lx48"Wx30"H low iron glass tank and a steel stand viewable from 3 sides with overflow on one end but it hasn't been a good year for me and the $ are just not there :(

What type of substrate? DSB? BB?
There is about 850 lbs of .2 - 1.2mm aragonite (Aragamax). It makes for a DSB. There is also 240 lbs in the refugium. I really liked the Aragamax Select slightly better but it wasn't worth the extra cost.

What type of fish is the Angel with the blue mouth and yellow mask on the eyes.
It is a Pomacanthus xanthometopon (Blueface Angel). I think it was the last fish I added about 8-02 as a small 2" juvenile. There are some corals I had to remove and my T. gigas. It ate different things at different ages some good and some bad.

Hi Sanjay,
If you pick me up at the airport on Thursday for MACNA I will bring you a box full you can have :D But you will have to take me to your house to help acclimate them properly :bum:

Corals are huge as well any pictures of tank when it was younger?
I think I have posted pictures each year. If they are not in my gallery let me know and I will upload them.

So how bout some pics of that 450 I see listed in your sig?
The 450 is much nicer (IMO). Its 2nd birthday will be on Dec 12th so I think I will leave it for then :)

Thanks for all the kind words!

Kevin

Your tank brings back memories! What are the current dimensions of this tank? I like the dimensions you are wanting to purchase for your next tank.

Is the tank acrylic?If so do mh lights(the heat) cause these tanks to lose there strength and bow.

is that a glass Tank? Is this normal for big tanks to start to fall apart after a few years?? Who made the tank?

kevinpo

What are the current dimensions of this tank?
The tank is 96"Lx44'Wx33.5"H. The front and back panels are 1" thick, the ends and top 3/4", and the bottom 1/2". 1" acrylic does distort the view a bit, especially at an angle but the 3/4" is fine.

Is the tank acrylic?If so do mh lights(the heat) cause these tanks to lose there strength and bow.
Yes the tank is acrylic. No it isn't the heat. The top surfaces never get above 80F. It is the combination of several factors. Acrylic is usually chemically bonded (not glued) together using a solvent which evaporates. The solvent breaks down the plastic and allows it to melt together. This changes the plastic slightly in that area. Normally it's not much of a factor and the bond will easily last for 10 years plus. Then we add the constant stress of the water pulling at the joint. This also is not that big of deal but is another factor. Taller tanks and ones made with thinner plastic have more effect than shorter ones. Then add the constant bombardment of UV A, B, and C and the result is crazing and cracking. Another factor is if the edges have been flame polished. Even a router used for rounding over the edges over can heat the plastic and add a heat history. The plastic remembers this heat history and is slightly weakend by it. None of the factors by themselves are much of a problem. It is the combination over time. I own 4 acrylic sumps and 8 large acrylic tanks all of which are more than four years old except for one tank. Only the tanks with halides show the crazing. It starts to show up at about the three year mark. I've had my friend Brent (Zephrant) look at them and he agrees. The joints from about 12" down all look fine on both the sides and the bottom.
The dilemma with large tanks is that glass tanks are so heavy and not that easy to drill holes in. Plus unless you use low iron glass the green tint is much more noticeable in larger tanks. This makes acrylic a very attractive option and for most lighting works excellent. I have about 3,300W of light over this tank.

Here is a picture of me back in Sept. 2003 helping Brent to reseal the back joint...

I just bought an acrylic tank.I plan to have x watt MH plus O.K.'d watt T5.I am thinking if this will happen to my tank then what can I do to prevent this.Do you have any thoughts.Thanks very nice tank.


I have a 96 x 42 x 32 coming and I am using all t-5 lighting for this very reason. I will be using two 4ft 8 bulb fixture and two 4ft 4 bulb fixtures. That's a total of 1,296 watts.

Plus I have will have no heat issues with the tank, much easier to cool the tank and room. Also remember t-5's produce about 10% more per watt than even metal halides. Plus I will have very few dead spots because every inch of the tank will have a bulb over it.


If you insist on mega watts, you can use ice cap ballasts and overdrive the 54 watt bulbs to between 80-85 watts each. You could turn my 1,296 watts into 1920-2040 without the heat issue ruining your tank and spending huge amounts of money trying to cool your tank and room.


Hope this helps,


Ken

Time for a frag sale to help fund a new aquarium.
I remember you starting up this aquarium. Seems like it just happened yesterday....

The big problem with this plan is that the Pittsburgh airport is 3 hrs from my house. If you fly into State College, PA I can easily make it work. :D Not only that, then you can even go home with some new stuff. :D :D

Sweet corals. That sucks about your tanks. I love your new dimensions. What type of equipment have you had over the past years?

kevinpo
08/26/2007, 06:48 AM
can you list some of the corals the blueface sampled that you had to remove?
Favia, Trachyphyllia, and Caulastrea. I thinl any LPS that doesn't sting would be in danger. It also nipped at 5-6 SPS corals at different ages. Any coral placed midway up or higher in the tank it would leave alone. They don't like exposing themselves over the reef where they can't dive into a bolt hole. The only current coral I see it nipping the tips of sometimes is Montipora digitata.

Kevin

I have the same equipment from the start except I added a second skimmer. It is a SK4200 with a 12" extension driven by an Iwaki MD100RLT. I also changed out the metal halide ballasts from standard PFO magnetic to PFO HQI. Over the years I have also run many different MH bulb conbinations. I'm currently running Reeflux 10,000K's. I also added ozone a few years ago.

Hello,
Wow! How did you dig up this old thread? :)
Happy holidays to you too.
Well I finally got a replacement tank and moved the tank inhabitants and equipment (6/15/08). It took me 4 months and 220 hours to complete the woodwork, plumbing, electrical, and move the livestock. The new tank dimensions are 96"x48"x30". I cut the larger colonies back about 50% but they have grown even larger than they originally were after 18 months. I also got rid of 350 lbs of liverock they had created. It is a peninsula style now with the overflow at one end and viewable from 3 sides. The system volume is 775 gallons and deposits about 8-10lbs of new coral per month. I have about 25,000 gal/hr flowing through it. 4 Tunze, 2,000gph return, and a 4,500 gal/hr closed loop.

It is located at my store now so I don't want to post any pictures or video as it may be deemed commercial.

Regards,
Kevin
