I need help on Submerged Sump

[luv012]

I have 320 G tank not setup yet and i am trying to make a sump for it.

i was thinking of making a sump out of 55g tank but would that be enough? I also have eheim 2080 filter to go with it.

What i planned was to have the mechanical filteration same as eheim cannister filter or aquaclear setup where water comes up from the bottem.

than 2nd chamber with scrubbies and ceramic rings.

than 3rd chamber as K1 / heater / pump.

if i made any mistake or any advice, i would greatly appriciate it!

Couple things, The Filter Pad on the Bottom is going to be a ***** to change and clean.

You want clean water to flow threw the pot scubbies or they clog with gunk. Maybe add a filter sock somehow .

Second, is there enough room in the sump to hold all the water from the tank when the pump shuts off?

Heres my current setup. (I'm building a tower to the left to hold a filter sock, and feed 100% clean water to the drip tray above the scubbies)

Also note. When the pump turns off, there is enough room in the last chamber to hold all the water from the tank.

the reason i did the first chamber is to have the intake pipe submerged to prevent noise, is that bad idea?

You only want the output pipe submerged a couple inches, or you get lots of air, burping, farting, from it.

If you are looking for a quiet intake you will need to make sure you do not introduce any air into your overflows. The only way I know how to do this is to fully submerse your overflow intake, others may chime in with different ways of doing this.

I think you want to keep the gunk away from your bio filtration, that's why most canisters and sumps have some sort of mech filtration first.

That is a ridiculous amount of media, and extreme overkill. Not to mention, a maintenance nightmare! I'd use media only in the middle compartment, and skip the sides.

Yeap. To do this you need to run a Herbie or Beananimal overflow system.

thank you everyone for help. So the 55g sump is overkill for the 325g tank? I've thought that people use 100g sump as standard.

the acrylic tank does have 3 holes inside the overflow compartment so I think i will make 2 submerged intake and 1 emergency like the bean setup. I just read about restricting the flow with ball valves and leaving 3rd one open for emergency. I think that is a great idea.

If you take a look at standard eheim canister filiters, the water is released on the bottom of the can and is distributed by the use of small cylinder media layer creating vortex and leaving the gunk settled on the bottom. I actually thought that by doing this, leaving the filter pad at the top to only filter small particles would keep the maintenance to minimal and less prone to cloggs in the sump section. So i should just ditch that idea and have the water drop from the top of the filter pad?

I think people are being confused with my plan as the entire thing being bio media and will clog. The first chamber is a copy of eheim filter system using same mech media, than pot scrubbies, than filter pad. they all are for mech filteration. second chamber is entirely bio media with scrubbies and ceramic rings.

if 55g sump is overkill, would you suggest 40g tank to be better? or 30g?

yes i ment to say "outlet" of the downpipe as shown in the drawing
