    hey all,

    while thinking of way of making high quality live rock for sump use, meaning its biological, has critters, sponge, algae etc, not pretty show rock made from bio-rock and home-made, i came up for an DIY LR filter so that i could rotate the rock so i didnt have to light the whole tub, and the mechanical filter i am looking at for hennie

    i cant draw, learning sketchup, will post pics when they look like some thing.
    this design has no light source, can be if made from glass, but works similar to a canister filter/ro unit/reverse flow skimmer.

    basically water comes in from the bottom and up a centrally mounted tube, made like a dipping jig to hold the rock. the top of the pipe is sealed, how does the water escape, 2 of the arms in the shelf terminate in 90 elbow joints, thus when forced out uses the jetwash of water to rotate the rocks on the xmas tree jig using the force of water.

    the water then leaves the mass container thru a piped exit at the bottom to stop stuff settling

    will add pics etc soon,sitting with cad dude tomorrow, hopefully a proto when i get the design and parts right.

    to rotate the jig, i am going to use a plastic ball with a whole cut thru it and the piping thru it, using the weight of the jig to spin on the ball like a ball-bearing...

    Sounds interesting and it nice that you are questioning the status quo, but I must say in this case there is a much simpler, more effective way. The good old DSB will outperform LR in my opinion any day. Lice rock is a good filter but a DSB is better.

    I'm with Kanga.

    Anyway what is the difference between your christmas tree spinning (could add flashing ligts:p) and a small powerhead spinning the water around a vertical pile of rocks. Yes the spinning tree will look a lot more wow. But you want the rock or water to go around in circles. Well it is easier to get the water moving. and a lot more simpler.

    Also even with pumps in your DT you still have stuff settles on the LR. Same will still happen, does not matter who does the spinning. And the detritus levels inside the rock will just build up and at the end act exactly like very fine bioballs. In your mind imagine the finest most delicate bio-balls - now what is the difference with LR. It is only about the surface area that they provide the bacteria to live on. You will not have the final O2 depleted area. So it will just be another Nitrate factory.

    But an impressive one. :thumbup:

    Ive designed my sump into a 4 chamber sump.
    Chamber 1. Overflow from the tank.
    2. LR and Chaeto.
    3. DSB
    4. Return to tank + chemical filteration.
    Every bit of water that passes through chamber 2 is filtered through the LR first, then the Chaeto thats above it.So basically the water flows from under the LR then out on the top. Get the picture?
