Sieve filter in a tote almost complete.

Will have to wait to use the sieve filter. Had SNAFU with the 150 gallon tank and had to drain it and move the eggs to a temporary system. The tank had no issues for years up until now. Go figure.

It's leaking below the center drain and am suspecting a crack in the 3 inch bulkhead fitting that holds the center drain. My replacement for a new tank will be a threaded Rhino drain that bolts in. I'm kind of tired of the cone shaped tank I have been using anyway.

Wow, sorry to hear. I was waiting to see it up and running.

Well hopefully this coming week. I should have the new tank up and running.

Sieve filter is operational. No problems and will try and take a picture tomorrow to post. The only thing that has surprised me is the amount of water that ends up in the waste trough. I did configure it so that water ends up back in to the system from the waste trough after it gets through the two 200 micron socks.

No feed waste or fecal material yet as the trout are still attached to their yolk sacs.

Some pictures in regards to the DIY parabolic wedge wire screen.

More pictures. The parabolic screen sits on top of a moving bed filter in a drum and the water that does not enter the trough and go to the sock filters ends up dropping into the biofilter. It than exits along with the sock filtered water into a sump tank. From there it's pump up though a DIY Sand and Gravel filter back to the fish tank.

Mid level flow from fish tank (not a surface flow drain). Just after the gate valve the bottom drain water enters vertically. Bottom drain water about 10 percent of flow ith the midlevel drain the other 90 percent. Similar to a Cornell Drain system but small scale DIY.

What's the flow rate going to the screen?

15 gpm.

The pipe that has the long slit. That directs the water across the wire screen. The flow is uneven.
A easy solution is break the water tension were the slot starts.

On my algae scrubber, I use a plastic sewing canvas. Available at any Walmart in the sewing, arts and crafts section.
Loosely held in place with zip ties.
A piece of air tube on the edges of the screen will also help to break the surface tension of the water. If the slot is cut wider.

Interesting.
