Hems 3'x2.5'x2.5' Take 2

Postby hemoi » Fri 17 Mar, 2006 4:57 pm

Hi All,

After a couple of months (or more) of planning, I have finally started on my next endeavour. It is not much bigger then my 2ft but it will hopefully be a vast improvement.
With only 7 months of experience in this hobby I am sure this tank will also only be a stepping stone..sshh don't let the SWMBO hear that. :pirate:

The image below shows the rough plan of the stand.
Image
It will be closed and dressed with Tasmanian blackwood to match the furniture in the unit.

This image is of the tank and closed loop system.
Image

I have started on the stand and believe it or not this has taken almost 3 weeks to get it to this stage. I did things the hard way and to dress all the pine to size which took just over a week.

I am hoping to finish it in the next 2 weeks. Let’s see how close I can get. :pirate:

A few more updates to come, just wanted to get things started.

Hi Kenny,

A 36"x36"x28" would have been my ideal size but due to the space I have in the room I had to cut it down. I love the cube look and wanted to keep as close to that as possible.
I have tall arms so 28" hight allows me to get the tank through the door and I can reach the bottom, assuming 4-5" of sand bed/plenum.

I am winging a lot of the design and calling on the kindness of the many experienced guys/gals on this forum. There is no way I woud have attempted this if it was not for this forum and it's members :clap:

Michael, I still need to put a couple of supports towards the back, as the tank sits a little short of the stand. I want all the corners of the tank to rest on the vertical supports including the back this should distribute the weight to the floor evenly. Also The cabinet top is going to be solid tasmanian blackwood at 32mm thick.
I have a quite a few photos of the contstruction which i will post on my website (so as not to bore everyone here with the details). If it works out i will create a step by step how to .pdf doc, but this is a long way away yet. :think:

Kenny, I am getting the tank made by St George Aquariums, they werent the cheapest but I guess if I have an issue, I should have a warranty etc.... I can PM you with the costs, not sure if it is appropriate to post here :nono:

An update: Stand is almost ready

Postby hemoi » Thu 06 Apr, 2006 9:30 pm

Time for an update:
The stand is taking a lot longer then the two weeks I expected to take. This is due to the fact that I have decided to use pine for the frame and then Tasmanian Blackwood to trim.

Frame with addtional pine support on the inside posts and 12mm mdf base.
Image

The 12mm MDF base was sealed with an oil based enamel primer/undercoat.
Image this is the one I used
I will also silicon the outer edges to ensure it is water proof.

This just shows the bottom of the base with blackwood edging
Image

A bad shot of inside painted and edged with the blackwood
Image

The doors also took almost a week to complete. There is a bit of detail, with all the edges 45o chamfered including the inner rails.
You can almost see it in the below image.
Image
I used blum 170deg hinges
Image

And skipping ahead about two weeks. All the doors are complete and the varnished with a polyeurethane finish x3 coats.

Thanks bmxer100. :cheers:

look what turned up today :clap:
It's got a total of 11 holes. The top is open as much as possible, but the braces at the front and back seem quite large. The tank is using 12mm glass and is reinforced at the bottom as well.

Getting closer to finishing.
Still outstanding:
1.Need to put the top on. All the boards have been joined and should be sanded, router and varnished before Easter
2. Electrical (waterproof) box: Still need to come up with the design.
3. Vents and extractor fans to be added.

Thanks Dejavu. I think it will still be a month or two before I have all the plumbing etc completed.

planning on doing the same with external overflow. at the back panel, do you use 2 smaller pieces glued to make up the height?

yes, the back panel is shorter and built up on the sides. They also added a couple of extra pieces of glass on the outside back along the join for extra support.

Update: All done, well upto cycle stage anyway.

Plumbing:
The plumbing is finally completed.
The 4 way hooked up to sequence dart. Chiller in the corner of the photo.
Image
A shot of the plumbing on the outside. I will build some timber corners to cover this.
Image

AquaC-EV180 Skimmer, still running in.
Image
Sump and plumbing complete
Image
Adding sand to the tank and dropped the bag.
Image
All locline in place and started adding sand

Hi Nick,

You have obviously put a lot of thought and planning into your tank Hem, looking very impressive so far, well done. :clap: How does the Ocean Motions unit perform with the Dart .

Thanks Andy.
A lot of stressful days especially with the plumbing and not knowing if I would just end up with a washing machine.

The dart is a little noisy, has a constant hum to it. I have lined the cabinet with sound proof foam which helps, but I can still hear it. The 4way is pretty good. A little hard to tell how the flow is at the moment because there is nothing in the tank but it seems to be ok. Lots of water movement at the surface. Not blowing the sand around so thats a good start.

Try dropping a small amount of food in the tank so you can see how much flow is coming out of the outlets, plus it will help to get some bacteria growing in the tank to help with the cycle. The Sequence pumps really don't like being restricted as they are a purely flow pump so I would say the humming is from the back pressure. Btw, love the sand all over the floor pic :roflmao: you know, no matter how careful you are, one day there will be a water all over the floor pic - it is innevitable. :konk:

Andy,

There shouldn't be too much back pressure on the Dart. The outlet has a 40mm outlet. I have a T with a 25mm outlet. the rest goes into the 4way which has two 25mm outlets always open. These are reduced to 3/4 (20mm) by the locline. The end result though is greater then the 40mm intial output. I think that is how it works. :crossfingers:

I have been "feeding" the tank for a few days already. I am hoping to seed the tank with some live sand on the weekend.

I am sure the next "oops" pic will be water on the carpet. :konk:

Unfortunately Hem that isn't how it works. As soon as you T off to the 25mm outlets you have created back pressure and it continues all the way with every length of hose/pipe, every turn the water has to take ie: elbows etc. It doesn't matter what the total outlets add up to at the end - every thing in between is creating back pressure. Trust me, if you fed the outlet of the Dart into a 40mm manifold which had 10 x 25mm outlets off it and they were all open, the water coming out of those 10 outlets would be quite a bit less than if the output came straight out of a length of 40mm pipe from the pump itself. Hope I explained it so it makes sense. :nut:

Here is a very rough schematic of the plumbing from the sequence dart.Will this setup cause undue backpressure ?

The 25mm T'd off goes to a 25mm pvc spray bar in the tank.
