Ira Posted April 4, 2009 Report Share Posted April 4, 2009 I'm having a mental breakdown...how many litres are in a standard 3ft tank? How long is a standard string? Twice the length from the middle to either end. Quote Link to comment Share on other sites More sharing options...
lmsmith Posted April 4, 2009 Author Report Share Posted April 4, 2009 It's .9x.4x.5 I'm getting about 180L, but I really really thought that it was more like 120L....That means with the sump, it's 100L. No wonder I have to add so much salt water! Quote Link to comment Share on other sites More sharing options...
Ira Posted April 4, 2009 Report Share Posted April 4, 2009 Yup, 180. A few liters less because you probably measured the outside of the glass dimensions minus a few liters because you wouldn't fill it up to the brim. Do you have the sump in the tank?(If so it's not a sump :lol: ) or are you referring to an overflow? Quote Link to comment Share on other sites More sharing options...
lmsmith Posted April 4, 2009 Author Report Share Posted April 4, 2009 oooohhhh....what's an overflow compared to a sump? I have a sump. Well, my tank overflows into a sump, then goes back to the tank... Quote Link to comment Share on other sites More sharing options...

The overflow is the part where the water overflows into(Counterintuitive, isn't it? :lol: ) to go into the sump. Quote Link to comment Share on other sites More sharing options...
kiwiplymouth Posted April 4, 2009 Report Share Posted April 4, 2009 The box at the back of the tank in this link is an overflow http://i78.photobucket.com/albums/j82/l ... /front.jpg Quote Link to comment Share on other sites More sharing options...
lmsmith Posted April 4, 2009 Author Report Share Posted April 4, 2009 Oh...I was busy trying to figure out why you'd have an overflow but no sump! Quote Link to comment Share on other sites More sharing options...
kiwiplymouth Posted April 4, 2009 Report Share Posted April 4, 2009 Extract from www.thereeftank.com An integral part of a sump is the "overflow". The overflow is the mechanism that drains water into the sump from the display tank. The overflow resides in or "hangs on" the display tank in a fixed position so that any water that rises above that level in the tank "overflows" through the drain into the sump. This is how the water level remains constant in the display tank. A wonderful side effect of using an overflow to drain water into a sump is that the surface of the water is constantly skimmed, removing undesirable surface films from the tank. This improves gas exchange with the water surface and aids in boosting oxygen levels and lowering CO2 within the tank. Also, not having the surface of your tank look like pond scum is a good thing, don't you agree? Quote Link to comment Share on other sites More sharing options...
