Here is an illustration to sort of "prove" my theory.

PLEASE NOTE: This illustration is not accurate, meaning the X values may not be the right corresponding Y values according to this function.

Please do not bash me down on this! It is just me thinking!

I am not trying to make any arguments!

EDIT: A horizontal asymptote, for those who may not know, is a value on a graph at which point the corresponding function will NEVER touch or cross. As X approaches positive infinity, according to my graph above, the function will never exceed that of 100%. Or more realistically, 99.9999999999999999999999...%.

awesome yeah using 2x4 which actually turned out to be about 1 1/2 x 3 1/2 for some reason but is still solid as! not sure on placement of the legs, the tank going on it is a floating base tank and the edges of the glass line up with the middle of the 2x4 just unsure of how I should be doing the legs, will ply board down the sides to give more strength, but red or blue for leg placement on my pic? legs are only going to be a foot long and will have one of those big metal brakets used for shelves supporting it along with the ply down the sides think this will be strong enough? i'm hoping to just over kill so I know its stong

either placement should be good as long as the legs are screwed in good.
and yes 2x4 is overkill for such a small tank. but too much is never a bad thing

hey buddy, just thought when you said about max flow rate you were probably going on about internal diameter not internal right?? if so then ID is 19-20mm what is the max flow there? good job I re read some other posts you have advised me on previously as the 1200l/h I was about to order would be too much for anything smaller, also can't remember what size the sump has to be? would 32L be okay? already have a 32L plastic box would be good if I could use that

 

[bitteraspects]

32 will be fine for the sump

the overflow rating is what i told you it was last time.
as for your pump, is it a 1200lph pump or is it 1200lph after 3-4' of head pressure?

 

[mini_matt]

think thats without any head hight max HH will be 3ft. my tank is full now

if its 1200 w/o head, then @ 3' it will not be pumping at 1200.

either way it will be fine.

Does it matter how far up the "T" part is from the bottom? Because I have mine up a little farther then the one in your pictures?

It still works, but there is a gargling sound it makes like every 10 seconds, I think this is because the pump I have is too small?

What do think?

Thanks!

im not sure if it matters or not still haven't really had a play with it, my pump turned up on friday I got it running with trouble, couldn't get a tap which I think is like an essencial part for starting the flow? was having some trouble with the check valve drawing in air before I blocked the output and filled the up pipe with water, still struggled with it keeping on going once the water flow stopped (head scratch) any tips peoples?

 

[bitteraspects]

what do you mean by "a tap"?

so you built your overflow, but havent primed it yet?

 

[fatheadminnow]

Mine works well.

Make sure that the entire system is air tight.

hey sorry diddnt get an email notification for some reason neways yeah havent primed it, if I pour water down the up tube it just runs out into the sump so I guess I need a tap to stop the water from flowing straight down but couldn't get one. plug the bottom some how I guess then fill the up tube with water and suck out the air through check valve turn on powerhead and pull out plug then it should work fine? do I need to check the valve thing often or should it be okay? cheers

what "tap" are you talking about? are you talking about a ball valve?

when you pour water into the breather pipe (the "up tube", as you called it) not all of it flows down to the sump. the section between the elbow and the "T" will have water in it. as long as the intake of your overflow is submerged, you will have water in the front side. then all you have to do is suck on the check valve airline until you get all the air out.

yeah ball valve sorry ok cool thanks I guess once you do it a few times u get the hang of it, atm I've got my tetra ex600 and another internal that I put a load of bio media in so its ok but will get the sump running after xmas thanks again
