You are obviously a child so I am going to let this go. We tried to help you and for some reason no answer was good enough for you. Any further smart ass comments will be your last.

This is a warning! Name calling will not be tolertated. You kept asking and getting super technical when you didn't understand the basic's to how it would balance. I will back any member here when it comes to this, not just a Mod. No name calling, no personal insulting, OR YOU WILL BE BANNED!

The part with the holes in it I call "The Snorkel" it's job is overflow back to the pond. There are many holes to insure that water will allways flow out. In the past, a leaf or build up of stuff has impeded the flow, this was designed to aleviate that problem.
The 3/4" pipe to the left is water in and going to the "bottom swirler".

I have holes like that but put an air hose in one of them really makes it bubble

Ok if I am understanding, you don't care that some of the water is actually flowing out of those holes and back into the barrel. As long as some of the water actually goes back into the pond. Cause it looks like the water that comes out of those holes is going to end up right back in the bio filter. Does that sound right? I am probably going to be building one this weekend so I have to get all the kinks worked out.

I don't think you quiete understand how it works. As water rises in the barrel, it overflows out through these holes. It has no place else to go but out to the pond. There are many holes to insure that water actually leaves through the 2" pipe.

Ah ok I get it now. For some reason I was thinking that it was still being "pumped" out through tubing. No the water gets pumped in, then it just sorta rises to the top and flows on out that pipe cause its the easiest escape route.

That depends on the head? How high is it and what does the pump spec sheet tell you the flow will be at that height?

I wish I would have found this forum before I started my pond!! Anyway..
I mentioned in a newbie thread that I just finished building my little pond, well almost. I still have some landscaping to do and need more plants for the pond. Anyway, I modified the skippy biofilter to be smaller and to have a wide spillway instead of a spout. My pond is around 400 gallons, and judging from waterfall filters in the stores and the water garden specialty store in my area I assumed that I could get away with making it smaller. I just got things up and running and have green water. I posted a thread asking advice in the newbie forum, and got a lot of advice. Mostly more plants and patience (I have very little of both) Reading up about this Doc Filter though, I was wondering if using tubing or netting would be better in my filter. Here's a pic of my media. My pump is submerged in the pond, so nothing that large will ever be in the filter. I don't have any sort of drain on it because the skippy site implied that it really wasn't neccessary. I have the pictured media in my filter first cut to fit the container perfectly as one layer, then cut into small pieces on top of that, finally I cut another piece to fit perfectly on top, mainly to keep all the little pieces in there. They weren't flowing out, but I was afraid they may eventually. Should I switch to the tubing or netting?

For a 1200gal pond is one 55gal drum will be enough for 15 fish? My pond water just can't get clear.

Yes it will, add some floating plants (I prefer water lettuce) and if you built the bio filter correctly and flow the right volume of water, it should clear up.

got 55gal drum with fence, layer blue filter pad, and layer of foam pad on top.Foam pad i clean everyday and left the blue pad and fence alone.Water from the foam pad i clean was dark green everyday, pond is clearing out a little bit. Today i decided to take a peek under the blue pad and see if any bacteria or any thing build up on the fence. I had add microlift pl 2 weeks ago. When i lift the blue pad up brown stuff break up and flow everywhere and nothing had build up on the fence.What is the brown stuff, dead algae?

If my pond is 2200 gallons, how many 55 gallon barrel filters do I need? Just 2? If I recall, wasn't it one 55 gallon bio filter for every 1000 gallons of pond water?

Very helpful sticky. Currently in process of constructing my doc filter. Wondering what the general consensus was with regards to flow rate through a 55g drum doc filter is in order to purify the water as best as possible? I read somewhere 5 minutes per inch and elsewhere I've read 5 minutes to fill the entire 55g. I have a valve so I can control the flow rate. What do you find best for clearest water?
