would this pond filter work?

So I have a 300g rubbermade. I want to put some native fish in it (not heating the pond). I was wondering if anyone has a setup like this for filtering it. Most of the designs I see that are DIY are from 55 gallon drums and I don't want one sitting next to or above this tank.

This is a very rough design just seeing if it would be doable.

OK, to explain my crappy drawing:

The red box would be a filter box setting on the bottom of the pond, with a screened or grated top to filter out any fish trying to commit suicide. Inside the box would be the mechanical filtration, two or three stages of filter pads.

The box would be plumbed to the threaded hole that comes with a drain plug on these tubs.

The outside would go to the pump (The blue box).

The pump would then push the water up to a chemical filtration box(Green Box). I'm thinking maybe an internal spraybar along the length of the box with the box filled almost all the way up with scrubbies. Then possibly with an oulet 1/3 the way op the box it could be a wet dry filter.

So that's where my brain started today. I still have to find fittings for the tank bottom, boxes to make the filters, and I have no wet/dry pump as of yet.

good start heres for people who don't like opening bmp.

I don't see why not, just make sure everything is sealed to avoid leakage.....

I'd recommend against what you have sketched up. You could go much simpler and effective...and still be able to use the drain for water changes.

I took a different approach with filtering the 150g Rubbermaid I set up for my lung.

I put a (~800gph) pump in the tub and plumbed it to push water into an under-the-bed style storage container (~4' x 18" x 8" tall).

I placed the storage container across the top of the Rubbermaid tub (near an edge), drilled 3 holes into the bottom of it (1 for input from the pump and two for gravity drain back to the tub), and filled it with all kinds of bio and mech filter materials.

It's basically a wet-dry filter in reverse. I used 99 cent store baskets to stack layers of filter materials.

You might want to run hoses from the gravity returns back to the tub (vs. letting it splash back), since it's hard to see into a tub with a lot of surface agitation.

I used the bottom drain in the tub to take out water (put a ball valve to a drain pipe to the yard).

do you have any pics of your setup?

I could just put one of these before the pump and throw a ball valve on it for draining

well asuming its deep u might have to swim to replace the mech media! but hey who cares, i swim with my fish!

it's not even three feet deep at the very top...
