Gordy,
There are some minor differences between mine and what you see on the videos (part one and two). I did originally include that little "flush line" for the left side, but he said he was using a 2500 gph pump ... mine is a 5000 gph, so I made the orffice in the "outlet" a little larger. What I found is this..... the flow onto the the wash-out screen is a little overwhelming for the system as he designed it, I still have that little wash-out tube that he provided in his updated video, but at 5000 gph it's pretty much useless.
The "trough" made of ABS in my system is on a slight downward grade, and I tried the modified screen that he used, but again at 5K gph it was a little too small for the volume of water. What I did was bought an expandable 12 x 18 " expandable window screen. Now... here's where my filter and his differs... He used 100 mesh SS screen. I couldn't get any of that cheaply, plus in some of the replies to his video, the 100 mesh clogs up fast. My expandable window screen has a layer of "sheer" curtain fabric between the layers of the sliding screens..... Too, my filter sock is made of the same "sheer" curtain material, set into a plastic " needle point hoop" and just trimmed to size. I don't know the "mesh" value of the sheer curtain material. but HECK! it works great.
Too, at 5000 gph, a lot of water spilled over the "solids" trough leading to the filter. I compensated for that by using the cut-out for that trough as a "splash redirector".
I'll try and post some photos with the water flow off so you can see what i'm talking about..
Once the sumac grows in you probably won't even see the filter at all .... I plan to place a hanging plant on to to help cover it too.
Gordy, after a 24 hour period, I was collecting almost baseball sized samples of solids caught. Even without my personal mods and improvisations ... it's a great system. Just a little tweeking and I'm sure this will be a great system. Kudos to Mr1Superb for the vids he posted. It's a really good system for capturing the larger stuff that bacteria can't handle.
Another difference was he built a wall to contain his bioballs..... I used a 5 gal carboy with the top cut off and holes drilled in similar to those he drilled into his "wall".
Cheers!
