Hi guys,

I have recently bought a 90g aquarium, 48"x18"x24" second hand and its been a while since I last had fish, so i'm welcoming any suggestions.

I have a aqua one CF1200 filter which I plan to integrate into a 3d rock wall background which came with the tank.



On the photo I have put a red dot where i'm thinking of making a hole for the intake, and in blue where the outtake will poke through, and yellow grate for an overflow for surface skimming.

Do you think these positions are ok? I am trying to blend everything into the rock wall, so i'm concentrating on indents and places which won't be so obvious when the tank is viewed.

I am also thinking of installing UGJ, to help with the maintenance of the tank, directing the flow towards the intake. I have been doing a lot of reading on UGJ and i'm thinking of 5/6 jets positioned at regular intervals to move to detritus towards the intake.

These will be driven by a powerhead, but for that number of jets, what output should I be looking for?

And also would I be able to position the powerhead behind the rock wall too? This would mean that it would be extremely hard to reach, so cleaning would not be possible. I was thinking of putting the powerhead in one of the cavities beneath my proposed outtake position (bottom right of the rock wall). I suppose i'm wondering, with UGJ do you need to clean the sponge on the powerhead often/at all? Also placing it behind the rock wall will also reduce the amount of detritus its exposed to.

So what do you think? Do these plans seem viable? As I have the opportunity now to play around and plan it out, I want to get it a good as possible before I start cycling and stocking the tank.

Thanks in advance for any ideas or help.

That's my biggest question regarding 3D backgrounds. They look amazing, but a bit of an engineering challenge with filter input/output.

I would think the "cave" in the upper right would be a good place for the output, otherwise you could get some pretty stagnant water up there.

Intake location looks good.

Always tough to say when it comes to positioning inputs and outputs into 3D polystyrene rocks...I'm in the middle of doing this myself.

I would consider not attaching your input to the BG - just hide it behind - and cut two rectangles (as well as your overflow) for intakes - silicone some mesh (I use plastic screen door mesh) over the holes and cover with dark foam. The foam can be rinsed occasionally.

You could also consider using a wye or tee to split your output into two outputs - might render the UGJ moot.

Here are some links that show how others have done it.

Thanks guys,

I like the idea of splitting the output and maybe putting a second output in the "cave" glaneon pointed out.

Still wondering about the powerhead for the UGJ. With the filter sucking the majority of the waste, I don't think much will make its way to the powerhead. So if I hide it behind the background where it will be pretty inaccessible, should I still put a sponge over the intake to stop the detritus from entering?
