Vanquish Posted January 14, 2005 Report Share Posted January 14, 2005 Hi Guys, i've got a 3ft long tank(1m), think its 400mm deep by 450mm high, have to measure with a ruler, dont have one atm anyway, how high should i fill my tank up?, high enough so that it looks right to the eye? 2-3 inchers from the top?, i have a fear of the thing bursting if too high , i dont want that. so yeah what is everyones advice on levels of tank water? please help, thanks in advance Quote Link to comment Share on other sites More sharing options...
Pegasus Posted January 14, 2005 Report Share Posted January 14, 2005 Hi Vanquish.. Welcome to the forums Around 25-30mm is the usual, and some people attach a strip across the top to hide the water line. Bill. BTW: Appears you had no replies to your first post, as it was in the middle of another discussion... No probs http://www.fnzas.org.nz/fishroom/viewto ... ght=#52246 sorry to hijack thread, but i've got a bala shark and 1 clown loach, they tend to bicker abit, but on the whole seem fine, is this a bad combo? doesn't seem like it so far Start a new thread or just add to this one. Hope you enjoy your visits Bill. Quote Link to comment Share on other sites More sharing options...
DiverJohn Posted January 14, 2005 Report Share Posted January 14, 2005 HI Vanquish I fill mine almost right to the top. When i get around to making a hood for mine it will probably hang 1-1.5cms over the edge to hide the water line as Bill said. With the lights on there is quite a reflection off the water surface. Hiding the water line IMO makes it look much nicer. But your question was about mainly concerned with bursting if its too full. Some one here *looks around* has got a calculator for working out the minimum thickness glass required for a given volume of water. So find that ruler and measure away... post yur exact measurements including the thickness of the glass and I am sure someone wil confirm it for you.

Caryl Posted January 14, 2005 Report Share Posted January 14, 2005 Assuming the tank is well made using the right glass thickness, I prefer to fill a tank so you can't see the waterline. Quote Link to comment Share on other sites More sharing options...
Alan Posted January 14, 2005 Report Share Posted January 14, 2005 What is the thickness of the glass, and what bracing does the tank have? Alan 104 Quote Link to comment Share on other sites More sharing options...
Lucid Posted January 14, 2005 Report Share Posted January 14, 2005 Hi Vanquish, I also would say it depends on bracing and glass thickness. I fill my tanks pretty much to the top aswell ( not quite tho, need some room at the top for having me hand in the tank and no water on the floor) as it hides the waterlevel as someone else has mentioned. B p.s if you are free and/or interested a few of us are getting thogether tommorow for a bbq, and if you are interested I am sure there is room for one more, just send Jude a message if you are interested.

Vanquish Posted January 14, 2005 Author Report Share Posted January 14, 2005 450mm high 396mm deep 1001mm long i measured one of the long planes and found it a VERY tiny amount under 6mm thick i had the tank originally made, and the top pieces of glass holding it were inside the tank, ie. not sitting on the top like they are now, i fillled the tank up and the middle piece fell in, resulting in buldging glass, which was RATHER scarey, but they remade the tank for me, they said it wasn't them who made it, but it was, so dad talked to them and i didn't have to pay for it again the glass holding things are NOW sitting on TOP of the tank, i hope this is stronger, anyway cheers for the help if you guys could work this out for me thanks Vanquish/Julian Quote Link to comment Share on other sites More sharing options...
Warren Posted January 14, 2005 Report Share Posted January 14, 2005 I make the glass safety factor 216.7% if filled right to the top and assuming full length top bracing. If the tank is well supported it should be ok filled to the top. Most aquariums are built to about this safety margin and very few fail. It's only the ones that haven't been siliconed properly that let go. If it is not braced then it only has 172.2% safety factor, - bordering on the low side...

Alan Posted January 14, 2005 Report Share Posted January 14, 2005 I wouldn't go over the 400 mark. I'd also be a bit inclined to put 2 little bits of glass the width of the brace, 25mm wide and glued, narrow edge to the front, to the brace on either side of the tank. This will give you a lot more glue surface than the 5mm you have at the moment. You only have to do this on the centre brace. Make sure any of the old glue, that is surplus is removed before doing this so as the joint is nice and tight. Alan 104 Quote Link to comment Share on other sites More sharing options...
Warren Posted January 14, 2005 Report Share Posted January 14, 2005 Yip, 380-400mm without the full width bracing sounds about right to me too. 8) Quote Link to comment Share on other sites More sharing options...
suphew Posted January 16, 2005 Report Share Posted January 16, 2005 Don't forget your water level will drop 1-2cm over a week due to evaperation (unless you have a tight fitting lid) so if you start with much more than 2-3cm from the top by the end of the week you could have a huge gap!
