Before i glue it.....opinions pls

[waynes world]

Just finished doing this DIY overflow setup for my 145g tank (6x2x2), i have used 1.5 inch pipe for this to get a 1350gph flow and will be returned with 2 500gph pumps, i can always change the pupms if there not enough but i am in the thinking that it should match the syphon flow with the bends and straight i have in the setup.

I first did this one

But then i decided to do this to the end straight, looks better....thats about it realy, and mite flow better. Just makes it that bit harder to get to the filter sponge when it needs cleaning, it still comes out just needs bending out.

I will be drilling 1/4 inch holes along the outlet end to give an even spray over the top media. At the minute its held together with electrical tape, just wanted to see what you think and changes you would make.


Another thing is the inlet, this is the pipe at the back in this pic

Would a T peace and say 6 inch of half pipe set at the water level make a better and quiter flow to the main down pipe?

Ye or Neh

thanks wayne

"just wanted to see what you think and changes you would make."

I'd advise you to place the/some/more machanical filtertration _before_ the bio-balls.

As for the inlet you should have some form of strainer on it. I used a 1.5" vent cap. I also dropped (uturned from the surface) the inlet down lower so as not to filter the fishes floating food before they lunch on it.

Hi Burko,
Those items are going to be seen to, i should of said, the inlet is 1 inch above water level at in the pics and the sump isnt filled yet. I am waiting for the other pump to arrive, hopefully today.

The mian part was if the overflow setup looks ok.

Thanks Burko, very eagle eyed

P.S I will be bringing the sump up closer to the bottom tank level to do away with the 9 inch drop in the overflow.

looks like u have made it correctly.. although i cant see a check valve/airline at the top for priming?

if your happy with how it looks go ahead and glue it

as burko said, u want something ontop of the inlet
check my thread to see what i did

Sorted then, i will hold you to it `that it will work`

I am getting a inlet strainer later today and will fitting that to the top of the inlet.

You know i forgot about the check valve, i will see if i can how you have done yours.
Just got some glass to divide the tank to add some K1 to the end after the sponges then floss before the pump/heater chamber.

Should have it going by weekend if the other pump arrives.

haha lucky you are on the other side of the world then

you'll struggle to prime it without being able to remove the air from the top of the system.. u dont have to get a check valve, u can just get a airline tap, suck the air out and turn the tap off when all the air is out..
just drill a hole at the top slightly smaller than the threaded barb connector (irrigation), and put either super glue or silicone around/in it
worked for me

Exactly what i have done mate, i am dying to try it but i need my other pump.

I realised also when i had glued it all together `MMmmm how do i get to the media etc to clean it.......`

So popped out today and got a detachable section to fit in the T section outlet.

Once done i will gets the pics on later of it working.....is that tempting fate LOL.

Been looking for some K1 for the sump but its dam expensive, well i found some and it was 25l bag at £38, way more than i need.

 

[waynes world]

Well then....what have i done wrong?

Pics first

Now the running is fine with just the one pump, i am still waiting for the next one to arrive.
With one the levle in the pump section sits half way down, you mite see in the pics. So i am hoping that when i have 2 pumps in there it will sit near twice the depth in the pump section with a few added litres.

Now i tryed it to see what would happen in a power cut ( i just pulled the pulled plug...dont worry i didnt short out the street LOL)

I waited for a while to see where the level would stop at in the sump...well it didnt, OH S**T

I noticed the tank level was dropping below the inlet, it was down by 1/2 inch before i turned the pump back on.

Any ideas where i have gone wrong, all i can think off is that the pipes in the tank U bend maybe is not sealed properly, BUT the water level was rising fairly fast for a small unsealed part of pipe.

HELP before i flood the house

You took off the uptoob
check your original design pic

I address this issue late in the below animation

Also I'm naow noticing that you went with the inlet fully submerged design
which calls for the "T" to be at the desired water level

You will need to add the outer loop, replace the Uptoob
and either raise the "T" or convert to the design in my animation

Sussed it, i just did it again and found the water is siphoning back threw the pump.

I better get a one way valve fitted.
