    Small scale indoor tank sieve filter almost complete

    Gave up on putting it into a blue barrel as for me to get the angle right, the trough would have had to been really far to one side of the barrel. Wasn't sure if I could do that with the Uniseals as they would have been at quite an angle due to the roundness of the barrel. I opted for making the trough out of 3 inch PVC vs. 2 inch, and putting the sieve in squarish tub I picked up at Dollar General for about $9.00. I will just drop the flow in via gravity through the top instead of plumbing in my intake pipe through the side of tub.

    This is part of a vary small inside system of only 150 gallons for the circular fish tank. The water flows from the bottom drain and the skimmer and simply drops via gravity onto the sieve filter. Solids are directed to two sock filters and the rest of the water drops into a moving bed filter directly under the sieve filter. All the water minus most of the solids are then pumped to the bottom of a downsized Birdman Sand and Gravel filter, and then over flow is back to the fish tank.


    I will tell you it was quite a challenge using the Uniseals in a thin walled tub. Shoving the trough through the Uniseals even well greased with vaseline, caused the tub to flex a lot which made things more difficult to line up the edges of the trough on the inside vs. the closed part of the PVC on each side. The transition of one side of the half cut out for the trough wanted to catch in the Uniseal.

    Will attach a squarish garbage can to the side for two sock filters soon. Tomorrow I am going to put the plumbing together.



    The 200 micron sieve screen I bought used from a member on this site. Thank you once again Koiphen! You people are the best!
    The risk I took was calculated, but man am I bad at math!

    IMHO, the thin wall will not hold water and eventually flood the clean side...

    Not sure what you mean? Can you elaborate?

    If it makes any difference the water will not stay in the tote very long as in it will drop immediately out of the bottom to an open blue barrel where the plastic media is. And we are looking at only 900 gph. Only a small amount of water should go into the trough and to the next container in which water will be pumped out to the sand and gravel filter.

    I welcome your comments but you need to provide more specifics.

    Thanks!

    Please come back. I want to know if I'm missing something.

    Thanks!

    Perhaps what ccna101 is trying to say is that the sides of the rubbermaid container might bow out under the water pressure. You could help support the sides with some 2x4s boxed around it.

    Thank you! Now I do understand. That said the water will fall through so rapidly into the moving bed filter directly underneath I'm not sure that will necessary. But I will see.

    like Nike says just do it. I would really use a 2x4 wood also better to be safe than sorry and a simple 2x4 frame takes little time and $

    Thanks. Make sense.

    BTW here is one out of a plastic tote also. As you can see the water goes out so quickly there really is no fear of the sides bursting. I see a few things I would not do but overall it seems to work. And of course it's not sieve material.

    There will be nothe much pressure on outside, but say the sieve clocks up . 2x4 frame would be a safety net. being indoor the tote should hold up. outdoor not chance. good work though Cecil. I believe this was scrap thay Zack had left over. very cool

    Yes you make a good case for the wooden frame and it will be indoors.

    " I believe this was scrap thay Zack had left over."

    Not sure what you mean?

    Hi Cecil,

    Yes IMHO, the plastic side wall are too thin to hold the water for a sieve application .

    Great DIY work btw, thank you for sharing.

    No issues with the tote holding water as there isn't much in the bottom as it passes immediately to the biofilter underneath it. The trough water passes to another container that houses 200 micron filter socks. Clean water from there goes to a sump and joins water overflow from the biofilter.

    Sorry can't post pics right now as for some reason Photobucket is not letting me upload photos. No reason for it; it just won't work. Since support there is a joke I will be changing to flickr.

    It's working great! No worries about the tote bursting as there is virtually no water in the bottom of it. There is a hole in the bottom where the water immediately dumps into the moving bed filter below it. I have the hole on top of the outside edge of the moving bed filter drum so it immediately goes down where the media is in the moving bed filter drum. (Diffuser in the bottom of the moving bed drum pushing the media up in the center and down the sides.)

    Only downside may be more water goes into the trough than I anticipated, but it's no big deal as that water gets dumped into two 200 micron filter socks mounted in a large waste basket, and then that water minus the solids that are trapped in the socks overflows to a sump tank of the system so no water is wasted. May be due to the angle of the filter not optimum?

    I wish I could post pictures here but I can't seem to upload pictures on Photobucket anymore. Every time I go to upload a picture it takes me back to the log in. So I log in AGAIN, and try to upload again, and it takes me back to the login. I have contacted Photobucket and they aren't much help. Switching over to Flickr but haven't had time to really do it.

    Good to hear it's working well!

    I tweaked something. The 3 inch trough filled to the brim and some water went over the edge of the trough to the bottom of the tote. I tilted the tote just a little and now the trough does not fill to the top and the water in the trough immediately goes to the sock filters.

    I'm kind of disappointed how much water does not go through the sieve but it is what it is.

    Edit:

    Removed the screen and power washed with a garden hose and nozzle and it was amazing how much more water goes through the sieve screen now. Didn't look very clogged but...
