Pictures or the Doc Bio Filter are attached. These may also be found at any time from my signature link.

The Doc filter uses 1/2" irrigation tubing cut about 1 1/2" long and there are about 7000 of them. The overflow goes down a cascading water and its peformance is superior to anything I have ever used in my almost 42 years of ponding. These tubes will never clogg and will backflush without any problems since they do not retain water or the impurities that some of the other medias do.

The output water is as clear as bottled drinking water and this filter will take a pea soup pond to clear in 48 hours after installation.

Is there any way we could get a parts list posted?

[DrDave]

If you go to the link, you will find this one and the new style "Doc Filter" in detail. Parts list is pretty much self explanatory.

Just a quick question:
Would it be better to have the dump valve on the actual bottom of the drum? It would seem that I would be guaranteed to get all the crud out and I would have a flat surface to attach to... Yes No?

Thanks.

[DrDave]

Yes, closer to the bottom is better. That means you will have to suspend your drum for the clearance required.

[Olee]

I plan on setting it on 2 layers of cinder block, therefore I will be placing the dump on the bottom. Thanks.

[DrDave]

You might want to use a piece of plywood between the cinder blocks and the drum to help distribute the weight. Otherwise, the drum may not last long.

[Olee]

I have already built a support structure out 2x4s but maybe laying a piece of plywood over that would provide even more support, thanks for the suggestion.

[DrDave]

These drums are not as bulletproof as you might think. I set mine down too hard and it cracked. Now I have to use plastic liners in it. I use it to have water on hand for my nursery and hospital aquariums.

I just posted another video on You Tube.

Dr. i'm trying out the plastic fencing also. I'm adding a twist by cutting them in smaller rolls like hair curler lengths and tying them with fishing line.It will be placed in a laundry bag with some bio balls that i had left over. Thanks for the concept.

[DrDave]

They provide surface area for the good guys to populate.

[lee]

[DrDave]

Yes they are worth having. That said, most any plastic will work.
