A 2" dump "ball valve" allows a flush to occur. Just like a toilet, it takes a lot of water moving suddenly to flush the media.

You can mix any of the media, it is the surface area that matters.

This is an excellant site, however, don't believe everything. For example, they discourage the use of 55 gallon drums, which in my opinion is far superior to what they reccommend.

A blend between the two makes for a Great filter...
I have cut up pipe and skippy pads in one,,,just skippy pads in the other
Both in 55 gal gal drums

i saw this website...i didnt like it too much
i saw that it didnt recommend the drums i too think they are excellent for filters

 

[c2c7390]

should the inlet be down through the middle or from the side from the bottom...or does this not matter either

 

[DrDave]

I think it will work best if it enters dead center and flows down so it floods the bottom equally and rises equally through the media to the overflow.

 

[c2c7390]

cant i do that from the side too with a T connector or something like that

i use scrubby pads from the dollar store, they are made from plastic,they are 4.5"x 6", and come in 5 packs for a dollar. same material as the floor scrubber material skippy recomends pretty much. they are not spongey. skippy said they tried sponges and had very poor results,due to rapid clogging. 30 packs give alittle over a cubic foot of media, stacked neatly. i use 50 packs, and they fill my 70 gallon stock tank filter nicely. i keep them in media bags, for moving between filters in basement and outside. the media bags are mesh utility bags also from dollar store.

heres what they look like... lots of surface area to colonize i cut mine in quarters.

 

[asudavew]

Cut up soda straws can also be used.
And the round nylon pot scrubbers. The old fashioned kind. Have loads of surface area for bacteria growth.

Now that I think about, imagine the bacteria those suckers grow in your sink!
YUCK
Here's a picture.

Thanks for the tip.

I think I will use 32 gallon rubber maid trash can.

That should be plenty of filtration for a 165 gallon pond.
