Greetings From Aquarium World

New at Aquarium World:

THE ABYSS PROJECT IS MOSTLY DONE - JUST THE SLOW PROCESS OF FINAL STOCKING GOING ON!  The 3600+ pounds of Cypress logs, limbs, and stumps have almost stopped leaching tannins into the water, and clarity is getting better by the week.  There are now ALMOST 10000 fish in the display, and it is really interesting to see the behaviors exhibited by the fish.  Who would of thought the tinfoil barbs were prone to hunting in an organized pack, even balling up smaller fish like dolphin, porpoise, tuna, and sharks do.  Nature at its finest.  More fish to come, and a few to remove that are simply not working out well in the new habitat.

Project History: On November 24th, 2009 we started a restoration project on the large "Abyss" aquarium.  Over the next couple months we will be restructuring the display into something new and interesting.  The entire project is expected to take between six and eighteen months depending on what issues we run into.  So after 12+ years it was time for a change, and to address structure maintenance that requires draining of the display.  So after almost a year of planning, saving, and brainstorming we have started the project, with a new direction for the aquarium.  

The project entails first draining the aquarium,, clamping the windows in place, removing the inhabitants  (for those that are wondering, all of the inhabitants of the display have either found new homes in the "Tide Pool" or will be relocated to public aquarium displays), resealing the windows, partial restructuring of portions of the rockwork, major restructuring of other display areas, lots of plumbing work.  Then we will rebuild the display area with new decor and cover structures..... yes a lot of work.  The display area of this aquarium is 45' X (12'-28').  That's larger than many home swimming pools... Its a big job and will take some time while we are waiting on the new window seals to cure properly.  Like any aquarium project, it just takes patience!

The "New Direction" will be to a very large freshwater display featuring only small size fish.  We have always wanted to show the true nature and beauty of schooling fish, and after serious contemplation, discussion, and surveying customers have decided to build a large display featuring schooling fish.... imagine a school of over 1000 neon tetras, huge schools of giant danios at the surface, and 1000's of other schooling fish.  In all the new display will feature over 20,000 fish!  Some have asked why we are making the change, others have claimed we are doing it from a cost basis.  The honest answer is that after 12 years, we wanted something different, something that was not common, something that as far as we can determine has either not been done, or is very rare.  As for the cost factor, the new display theme will be more expensive to set up than keeping with the old (new animals, decor, etc).  Maintenance cost will be almost identical.  Sure we wont have the cost of the salt, but have you ever fed 20,000+ animals, or expended the labor to maintain an aquarium with those stocking densities?  Our calculations show that the overall expense will be about the same whether we go to the new format, or stay with the old... so we decided to do something new!

UPDATES:

Have you ever started a project that was really big, planned for the "big scenario" and what might happen, all the while hoping that the better faster plan will work?  Well, We had initially planned to reseal the windows of the abyss tank, maintaining the original grout and inner seal system that upon visual inspection appeared to be in excellent shape.  Once we started the physical reseal process we found a couple inclusions in the original tank waterproofing (epoxy coating system) that were very close to the window seal system.  Rather than proceed with our original plan, the "big scenario" kicked in.  On January 19th we started the removal of the windows (not an easy task.... they are dang heavy and require some "special" equipment) to completely re-surface and re-finish all the window areas and start with what is effectively a new install of the windows.  We had hoped we would not need to do this, but it was the right thing to do (otherwise we might have had to do it in as few as a couple years)... If its worth fixing, fix it right!  Unfortunately this set our entire timeline back quite a bit (and made a really big mess for a few days).  The window areas have now been ground down to bear concrete, new waterproofing and epoxy systems re-installed... And the windows are back in!  The new window seals and grout system has been installed, the surface seals have skinned over enough that we can start working on the walls again so we are now back at it.  The up side is that the windows are now effectively new as they were almost 13 years ago.  The down side is that the complete reseal takes a bit more time to cure.  Our new hydrostat test (testing pressure seals) will come around the beginning of March (have to wait for hundreds of pounds of silicone to fully cure).  More as it comes (we have added some more pictures).

Well; As they say, expect the unexpected! There have a few delays in the acquisition of some of the decor and coating materials, etc.,  but those are finally resolved.... aren't huge projects fun (lol).   The project is now progressing once again.  This is a huge project and we appreciate all those that understand the delays, we wish they weren't there, but they were unavoidable for the most part.  Bottom line is we want the job done right so it doesn't have to be done again for many years.  One customer likened this project to building a house, you just never know what's going to come up next (he is a home builder by the way).

THE COATING MATERIALS ARE FINALLY HERE!!!!  Whoop!  We have started the final coating progress after a lengthy delay in material availability and should have the coating process done by next week (that the end of May for those that are watching).  All the wood and decor has finally arrived also.  We were able to get some of the most incredible wood pieces we have ever seen, including some very large cypress stumps (one we have split to make two pieces that are 9ftx4ftx5ft tall!!).  In all we have close to 300 decor items that are going into the display!  As soon as the coatings are dry its time to start decorating and prep for filling the tank.  If all goes well we should be filling the tank on or around May 31st!

Coatings are all done, the massive mound of rock has been re-positioned (we forgot how old we were, and rock is dang heavy...go figure).

Wood is being mounted and epoxy bolted in place.  Next is gravel, floor decor, other decor, and finalize the internal plumbing (hundreds of fittings to glue... in a confined space...good thing we have ventilation fans!)  Plumbing should be done on June 3rd. Then we pressurize the system for a quick hydro test and then start filling the tank.

Well the tank has been up and running for a couple of months and now has a bit over 7000 inhabitants in it!  We have added several new pictures from the final construction days.  The system is stable and the wood is leaching (process where the thousands of pound of Cypress in the tank leaches tannins into the water - makes the water look green with the halide lighting even though it is actually brown ).  We are using carbon and ozone to reduce the tannin content in the water and as of August

More as it comes

 

Here as some photos of the work as it is progressing.  We will try to post a timeline that we have posted in the store as soon as we can figure out how to present it on the website (its pretty big!). WE HAVE BEEN WORKING AND TAKING PICTURES, We will post the pictures later, finishing the project is more important than posting pics at this point.

"Pisser" the Passer Angel in his new Tang Sea Home             Most of the water is gone, We are waiting for a few of the larger animals to be picked up prior to draining the reaming 30" of water.

Removing Coral Decor. Most of the decor gone from the right side of the display
The boat is gone and we are working on the left side Just a bit of silliness!
Back left corner during drain Same back left corner after rock wall removal
Last bit of rock to be stacked This is what 26,000+ lbs of rock looks like ..lot of work!
Butch in the tub being transferred to the hauling trailer on his way to Sea Center Texas.. He measured in at 60" 25lbs Some fun "on the beach in the Abyss"
This is hard to see, but that white patch is the first scraping on the tank walls as we prep the walls for blasting and re-coating More on the walls as bubbles in the old coating system are ruptured to allow the concrete to fully dry before blasting and re-coating.
Windows clamped in place for seal work What we Found - waterproofing failure to close to the window seal area.  Yes that is moisture in the concrete 1/2" away.  Time to refinish the entire window area!
First Window in the slings and ready to remove.  These windows are almost 2000 lbs each, so removal by hand is not an option. All Three windows are out.  Yes that is the third window still hanging in the lift system.
The window rebates (rebate is the lip the windows fit into). after complete grinding.  Grinding is very messy! New waterproofing and epoxy sealing system in place.
Windows back in place and the seal system installed.  Now we wait for the silicone to fully skim over before we start grinding and prepping the interior walls for recoat. Surface preparation involved three steps of scraping loose material, full surface re-grind (hundreds of pounds of old coating and surface concrete, then base coat epoxy system in preparation for the final recoat. A tremendous amount of work!
Lots and lots of wood! One of several Cypress stumps we were able to get

The Walls with the first base coat of epoxy Final surface preparation for the final epoxy coating
Final Wall coat going on! The finish of the first floor coating, now to move 26,000 lbs of rock, then grind and coat the floor area under the rock
The rock is almost all moved and anchor ropes are installed.  (anchor ropes are for strapping down decor if they cannot be anchored by weight or epoxy bolting) Most of the cleanup is done and we where getting ready to grind the floor area that was covered by the rockwork and then prep and coat the remaining floor area.
Final floor coating is done and wood is being moved in (view of the north end of the display) View of South end of the display as we lower in the wood.  (the wall is 14 feet to the top edge to give size reference)
Moving and mounting the first piece of wood (~300 lbs) Layout and mounting preparation (yes we shaped some pieces with an electric chainsaw to get the best fit)

Large wood requires multiple mounting points, so pegs are used to position and measure the mounting pin lengths. The tape indicates primary mounting points before secondary pins are drilled and pinned to hold the wood. Many of these pieces have a buoyancy of several hundred pounds, so proper attachment is important
The wood on the north end of the tank is all mounted and the gravel and stone bottom is being installed The south end as we are dumping in tons of gravel for the bottom
North end after gravel and artificial plants South end just prior to filling
Fish have arrived! Poor underwater picture of a few of the fish
View from the outside looking through about 10 feet of water at the north corner of the display.  The water still has lots of tannins leaching from the wood which gives it a very green look under metal halide lighting (its actually brown)

MORE PICTURES AS THE WATER CLEARS

Things to be done: (MOVED FROM ABOVE THE PICTURES NOW THAT ALMOST EVERYTHING IS DONE)

 

bullet

Re-plumb the system to isolate the "Tang Sea" into is own ~5000 gallon display system (new capacity now that we finished the rebuild and enlargement on that display, as well as increasing the water depth). DONE

bullet

Drain the main tank to approximately 30" of water to allow capture on the fish and start of work on the restoration. DONE

bullet

Start work on the window re-seal (takes week for the seal to completely dry and become ready for the new seal system to be installed). DONE

bullet

Arrange for "Butch" the green moray, the two large puffers, the large batfish ("Orby" and "Willy"), and a few other large fish to be transported to their new homes at public aquariums. DONE

bullet

Finish draining the tank and capture of remaining inhabitants DONE

bullet

Removal of the over 400 pieces of "Coral Decor" from the display, as well as the "S.S. Minnow" (the sunken boat). DONE

bullet

Moving over 25,000 lbs of rockwork away from the walls in preparation for re-surfacing the walls (much like a swimming pool, water slowly degrades the epoxy coatings and periodically the wall coatings must be re-finished to maintain the concrete tank structural integrity). Done    

bullet

Re-finish the walls. DONE AT LAST 

bullet

Modifications to display plumbing. Almost Done. Will finish final internal plumbing on June 3rd

bullet

New window sealing system installation STARTED New Sealing System Install will be complete January 16 Well, the new seals took longer than expected due to removing the windows to completely re-finish the window system.  Seals were finished January 28.  Now we wait for them to cure.... FINALLY DONE.. Seal system is done!

bullet

Installation of the new decor Almost Done.... The new Wood is Fantastic! Will be done on June 3rd.  DONE
