Christian Posted July 9, 2009 Share Posted July 9, 2009 I want to build this fish tank http://www.sciviews....jean/index.html but nano sized. I like how has the drop off but I also like the shape of an "L" tank and would like to put them to gather. I would put the drop off on the short side of the "L". I need to know how to calculate the volume because I don't want the tank to be more than 20gallions to cut down on the cost of glass. I also want it to fit in a 30inch by 15inch space. I also want to put a sump/built in filter. So any thought on how to build the tank and the filtration system would be appreciated. Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted July 9, 2009 Share Posted July 9, 2009 That is one of the coolest tanks I have seen. I'd love to see that thing in person, as well as have one! Can't really help with the build though, other than to say the short side height will determine the glass thickness. Quote Link to comment Share on other sites More sharing options...
Christian Posted July 9, 2009 Author Share Posted July 9, 2009 what do you mean the short side? I wanted the drop off to be about 2 feet deep. Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted July 9, 2009 Share Posted July 9, 2009 The drop off side. The pressure from the height of the water column will determine how thick the glass, or acrylic, needs to be. At 24" I think you'd have to look at 1/2" thick, or better, glass. Quote Link to comment Share on other sites More sharing options...
Christian Posted July 9, 2009 Author Share Posted July 9, 2009 ok tanks so all the glass for the intiar tank will have to be 1/2 inch or just that pice of glass? Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted July 9, 2009 Share Posted July 9, 2009 Probably the whole thing. And again, that is just a guess on my part. You should definitely talk with someone who has built tanks before. Quote Link to comment Share on other sites More sharing options...
Christian Posted July 9, 2009 Author Share Posted July 9, 2009 I don't know any one that has built a tank. thanks Quote Link to comment Share on other sites More sharing options...
Zarathustra2 Posted July 10, 2009 Share Posted July 10, 2009 for colume the easiest way is to treat it as two tanks and then add. So you have one "rectangle" with a certian size and one square with a certian size and add them. Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted July 10, 2009 Share Posted July 10, 2009 You might ask Hobogato, although his experience is mostly(all?) in acrylic. He comes here every now and then, so you might shoot him a PM on MAAST. Direct him to this thread so we can all learn. Quote Link to comment Share on other sites More sharing options...
caferacermike Posted July 10, 2009 Share Posted July 10, 2009 Build it from acrylic. So much easier. Quote Link to comment Share on other sites More sharing options...
Christian Posted July 10, 2009 Author Share Posted July 10, 2009 but so much more $ that I don't have. Quote Link to comment Share on other sites More sharing options...
dustint21 Posted July 10, 2009 Share Posted July 10, 2009 Mike is right acrylic is the best way and ACE is your guy! Quote Link to comment Share on other sites More sharing options...
Bill B Posted July 10, 2009 Share Posted July 10, 2009 I'm sure you can find a formula if you google, but 1 cubic foot is 7.5 gallons. So it would have to be a little less than 3 cubic feet to be less than 20 gallons. Quote Link to comment Share on other sites More sharing options...
Christian Posted July 10, 2009 Author Share Posted July 10, 2009 Here is waht I came up with I know the tank is going to be more than 20g with thees dimentions for the tank.well It's kinda hard to say the dimentions because it's not a rectangle. Ok thaat is the main part of the tank, now the drop off is going to be were the 12inch wall is and tis going to sit on this table. Quote Link to comment Share on other sites More sharing options...
Zarathustra2 Posted July 10, 2009 Share Posted July 10, 2009 Calculate the area overall as two rectangles. Then figure out the volume of the triangle that you have taken away and subtract. That being said i think you are weakening your basic design and makeing your stand build a lot more difficult. I personally would say that if you are in this forum asking the question you probably don't have the experience to be able to pull this off. Not an insult or anything but the general box shapes are much easier to put together and use. I would just think that you would need to be an expert to pull off a non-standard design like this and be confident that it will hold for the long term. Why not go with the standard "L" design. Then you only have square joints so wont need a special jig to put together the sloping design you have. And maybe i am wrong and you have loads of glass experience.

Christian Posted July 10, 2009 Author Share Posted July 10, 2009 no I have no glass experience at all but I'm willing to learn from my mistacks and just want a chalange. And i want some thing that others don't have so If I make a mastake that I try it a different way. Quote Link to comment Share on other sites More sharing options...
dustint21 Posted July 11, 2009 Share Posted July 11, 2009 If you do the angled bottom its going to be bare glass? How will you keep sand or rock or anything on it? If you keep the angle I would use acyrlic for sure. That a decent load on a glass seem. Quote Link to comment Share on other sites More sharing options...

Christian Posted July 13, 2009 Author Share Posted July 13, 2009 no their is no angled bottom, look at this it has mor information about the tank. http://www.thereeftank.com/forums/f6/i-want-to-build-133787.html and its preaty much all 90 degre angles except for 1 wall.

Christian Posted July 16, 2009 Author Share Posted July 16, 2009 well here is the desine for the tank. Quote Link to comment Share on other sites More sharing options...
mFrame Posted July 16, 2009 Share Posted July 16, 2009 I'd love to see it, but wonder why you're incorporating the angle from the above down view. I would think that it would be much simpler with rectangles than trying to add the angle because you'll have to bevel the glass on the sides. Also building a stand to fit it will be a bit odd. Cool concept though Quote Link to comment Share on other sites More sharing options...
Christian Posted July 16, 2009 Author Share Posted July 16, 2009 well I wanter dome thing interesting and so i figured that I would have to make it my self and I also did not want it to be square. Quote Link to comment Share on other sites More sharing options...
mFrame Posted July 16, 2009 Share Posted July 16, 2009 Unique is cool, but just thinking that for a first attempt at building a tank your success will hinge on the level of complexity. I'd think that if you can build it (and build it well) without the angle and gain the experience, you won't have an issue selling it later when you want to try the more complex design. Baby steps....

Christian Posted July 16, 2009 Author Share Posted July 16, 2009 ya well I thought a bout taking my 20g and 10g tank and making a smaller one to start off than I f it works and all is good intill about like november than I will build the bigger one.
