new wooden hill stream tank (constr jrnl)
 
hi all,

In this hill stream paludarium thread I mentioned that I find the concept good, but the execution can be taken further (especially larger!), to create more different pieces of stream, enabling the keeping of more ´normal´ fish species like tetras. I also want to create walls that are less vertical and more like a slope (at least at some places).

At the same time my wife and I discussed the fact that we could do with some more space in the living room, where this paludarium is situated. And as another room in the house became available (due to change of work), the decision was made to replace the two existing tanks with a large one in a dedicated room.

Here is a Sketchup picture of the room with the new viv.
http://www.fotografiewimvanvelzen.nl...ijke-poten.jpg

Dimensions of the viv will be 215cm at the left end, 280cm at the other side and an inner height of 135cm. The depth is 95cm at the left side and 70cm at the

right side. The two ´legs´ are positioned at a bit more than a 100 degrees towards each other.


To get a better idea what I wanted I did a lot of sketching, like this one:
http://www.fotografiewimvanvelzen.nl...shout-comp.jpg
In the final design the room under the tank is used and covered by some sheets of plywood.


Artist´s impression of the tank; I use the back window to create some depth (the window faces North, so the light will be rather diffuse)
http://www.fotografiewimvanvelzen.nl...gehele-bak.jpg


Beneath the actual tank there is room for making RO water (to be mixed with a bit of tap water), automatic water refreshing and a large (160x50x50cm) tank in which four large pond pumps will be placed, that are essential for making a hill stream tank.

--------------------------------------------------------------------------

September last year I started the constructional work (which I plan to end at about June this year). The material used is a good 18mm plywood, which will be

covered with epoxy and glassfiber mats.

The best start of course is to have an empty room...

http://www.fotografiewimvanvelzen.nl...090919-001.jpg

(Before this I painted the wall with some moisture resistant coating.)

I glue the plywood pieces with Poly-urethane glue (don´t know the English equivalent) - even if I wanted, there would have been no space to work with screws.

http://www.fotografiewimvanvelzen.nl...090920-003.jpg


Part of the automatic refreshing system: a small pump, pumping water to the drain regularely, which will be replaced by a 3:1 RO - tap water mix from the

reservoirs.

http://www.fotografiewimvanvelzen.nl...091004-012.jpg

The tank through which the water will flow back to the large pumps. There is a biological filter inside, like used for large fish tanks.

http://www.fotografiewimvanvelzen.nl...091020-001.jpg

Where the water will flow back to the pumps:
http://www.fotografiewimvanvelzen.nl...091104-002.jpg


Packed in foam, to avoid loss of warmth (by the way, the pumps will act as heaters):
http://www.fotografiewimvanvelzen.nl...091104-005.jpg

The right part is higher as part of the ´hill´ and to enable access to the pumps in the tank:
http://www.fotografiewimvanvelzen.nl...091104-011.jpg

--------------------------------------------------------------------------

The walls behind the tank are covered with styropar sheets for insulation:
http://www.fotografiewimvanvelzen.nl...091125-001.jpg

The standing plywood back:
http://www.fotografiewimvanvelzen.nl...091111-001.jpg

Dividing the part for the lights and ventilators (the holes are 40mm in diameter and will be covered with wire mesh)

http://www.fotografiewimvanvelzen.nl...091125-006.jpg


A lot of holes for the pipes (here the ones that will bring the water back from the pumps into the tank):
http://www.fotografiewimvanvelzen.nl...100103-002.jpg


I sawed the pieces of plywood behind which the glass windows will be placed (45cm high and then sliding ones on top).
http://www.fotografiewimvanvelzen.nl...100104-010.jpg

Inside, below the lights (the boxes at the end are to place some ventilators for circulation inside the tank):

http://www.fotografiewimvanvelzen.nl...100104-008.jpg

Between the pumps and the tank I place some taps to regulate the amount of water flowing through each pipe. In the picture they stand above the floor, but once glued they will hang under the tank. Pipes are 40mm in diameter. The total pump capacity is 19000 liters an hour (5000 US gallons), although some is lost because of the height to which the water is pumped.
http://www.fotografiewimvanvelzen.nl...100113-001.jpg

At these points in the rear end of the tank, the water will flow back to the reservoir under the tank:

http://www.fotografiewimvanvelzen.nl...100113-002.jpg

In the left side there is another pump under the tank for a waterfall at that side:

http://www.fotografiewimvanvelzen.nl...100113-004.jpg




I hope the pictures help you to understand what I am doing - I feel my technical English is lacking a bit...

Questions, suggestions and criticism is very much appreciated. Some way this is quite an adventure as there are so few examples of this type of tank building (I fortunate enough to get the help of the man behind this tank, Hans Pietersma).
Any input is welcome!

I love being hated this way :cool:
The room I have is a real blessing, OTOH this one will replace the two existing ones.

There is still a lot of work to do, so enough stuff to follow if you allow me some time :eek:

I shall give you some time :D How does a week sound?:) Again i appreciate your threads, the detail, time and artistic skills spent on your projects shows. When you are finished i have a spare tank that needs to get finished its not as big as your room but its (if my formula is correct its been a while converting inchs to centimeters) 182cm long by 61cm wide and 76cm tall. i hope i did that right... anyone any better at math then me? 1inch = about 2.5cm? Now i feel dumb

What are you doing online? Get back to working on this already! I can't wait to see it finished. So do you have any ideas for inhabitants yet?

Re: new wooden hill stream tank (constr jrnl)
 
Thank you for the week, I am afraid I need just a little bit more :rolleyes:

An inch is 2.54cm (at least in the UK). So your tank would be 72" x 24" x 30"?


As for the inhabitants, I just think about moving the frogs, gekkos and fishes from my exisiting tanks and see how they do. Probably some more fishes and some new generations of Mannophryne would be nice...

I am very, very impressed with this build!!! You detail is amazing and don't worry about your technical english, you are doing great.

That is one of the most impressive undertakings I have seen. I am completely impressed by what you have acomplished. Great job. I, like others, can't wait to see the finish results.

Ok Ok a week and a half will work for me :D

Perfect on with the size, but i have it started and after looking at your builds im ready to rip out everything ive done! Wish i could figure out what to put in there.

Again beautiful and cant wait for the updates!!!!

I plan to get the epoxy stuff this week, so I could do only a few minor things.

First I installed the tubes for the water that flows back to the reservoir. I havenīt glued them yet, as I first want to do the epoxy.
http://www.fotografiewimvanvelzen.nl...100131-003.jpg

I placed the acryl glass window; of course the frame will be hidden in the background once made.

Cleaned the tank a bit:

Or better this way?
http://www.fotografiewimvanvelzen.nl...100131-009.jpg

I also played around with the division of land and water. Just some pieces of foam to get a rough idea.

THIS IS SPARTA! Hahaha, just kidding, that's how excited this build made me. It looks insane. I really can't wait until it's done. I hate finding cool threads like this before they are done. I have no patience.

You never really realise the size of the cage or say to your self this is huge, until you can fit inside it.

http://www.totallyterrariums.com/ima...sure/cage6.JPG

:D

Lovin' the work so far, maybe some more pictures of how the plumbing looks underneath? How deep is the water going to be? Will there be a drip wall of some type? What's going to light this beast?


Keep it up!

wimvanvelzen 02-01-2010 06:07 PM

Re: new wooden hill stream tank (constr jrnl)
 
hi Nick,

I havenīt really more photos than I already showed. Basically the plumbing is like this:

there is a tap at left side with a RO attached. Then there is small tank with an RO water reservoir (about 20 gallons) and a rest water reservoir (about 8 gallons).
At the right hand side under the tank is a 64x20x20inch tank used as a biological filter; the 4 pumps will be placed in there delivering a 5000 gallons an hour (well, less because of the height of about 3 feet to the points where the water flows into the actual vivarium).

I have 4 points where the water flows into the viv, 2 right above the right hand side of the tank, one about 1.5 feet higher and one with a horizontal arm attached to create a broad dripping wall (well, a bit more than just dripping - make that small waterfalls).

At the left hand side I also have a pump as used for central heating systems to create a 3 ft high waterfall there.


The water refreshing system is simple. Each week I plan to run a little pump in the large reservoir for a couple of minuts, to get about 10 gallons of water to the sewer. Then I run another small pump in the RO water reservoir to add 7 gallons of RO water and then again another small pump to pump 3 gallons of rest water into the reservoir. That way I can get water hardness (is that the technical frase?) I like.

Then there is a lot of water evaporating from the tank. I just can pump RO water to get things back to the level I want.


The water level inside the vivarium will be mainly 30cm / 12inch, apart from the right hand side where I try to get water levels of 10cm and 40cm higher respectively (a bit like rapids in a small burn).

Between the pumps and the actual viv I made a connecting pipe and 4 taps (cocks?) enabling a precise regulation of the amount of water flowing at the different points into the viv.


Again, I hope I make myself clear - just ask in case I am not :eek:

Re: new wooden hill stream tank (constr jrnl)
 
About lights: I have in the present hill stream tank 4 80W T5 lights (everything is 220V here). Then I have got some small lights (12W) for a slow start of the morning and a slow end of the day (poor manīs dimming system :)). Apart from that a couple of hours a 40W heating lamp and a UV emitting light for the lizards.

I my other viv there are 2 80W T5 lights and a couple of 36W PL lights.


I plan to use all of these as well as two 70W spotlights to add some atmosphere in the evenings (with the 80W lights out).

Re: new wooden hill stream tank (constr jrnl)
 
I won't forget :) Just nothing new to show. I did buy a lot of epoxy and glasfiber this week as well as a dripping/rain system. I will work on it tomorrow and post some pics if there anything I could be proud of ;)

This is quite the undertaking! Makes me feel comfortable about doing a large display in a reno house. Please keep your progress updated on here.

If you didn't live in the Netherlands, I'd have no problem giving you this:
http://i38.photobucket.com/albums/e1...5/SA400004.jpg
I'd imagine shipping would be quite high. Good luck!

wimvanvelzen 02-25-2010 06:30 PM

Re: new wooden hill stream tank (constr jrnl)
 
Awesome piece of wood, Harold! Thanks for the offer, but it would get costly indeed.

I hope to have something to show within a few days. I am working hard on the epoxy layers inside the wood and on the dripping/raining system. I'll be back!

wimvanvelzen 02-28-2010 04:26 PM

Re: new wooden hill stream tank (constr jrnl)
 
Well, nothing sexy to show but I did some important things. Here are the pictures!

I put multiple layers of epoxy and glassfiber (for the waterpart, the landpart just one layer) in the tank. As you can see I am not a tidy working craftsman :(

http://www.fotografiewimvanvelzen.nl...100228-001.jpg

http://www.fotografiewimvanvelzen.nl...100228-002.jpg

http://www.fotografiewimvanvelzen.nl...100228-003.jpg

I think that everything is watertight - Iīll test that this week for the lowest few inches. After the front windows are glued in, I can check the entire system.
I also added 25 points for a dripping system near the backwalls and 60 in the lid. The last ones are to mimick the after-rain effect in a forest where large drips just fall at irregular intervals. For real rain, there is much more needed of course!
The system is called Micro Drip, by German based Gardena. I expect to run in 15 - 30 minuts each day, according to need.
I will make the orange parts black, btw. Looks rather ugly now!

When standing in front of the tank, you cannot see the lid and dripping sytem. When seated, you can. Well, that is trade off I am prepared to take!

http://www.fotografiewimvanvelzen.nl...100228-004.jpg

http://www.fotografiewimvanvelzen.nl...100228-005.jpg

You can see 2 of 4 ventilators, meant to provide internal circulation (wind). Of course Iīll put some maze in front of it as well as in front of the round ventilation holes.

jpstod 02-28-2010 07:00 PM

Re: new wooden hill stream tank (constr jrnl)
 
When you get done you can come build us all one.

The Drip system is just a garden drip system or is it designed for us in Vivariums?
