    Trickle filter stand.

    Hi Guys/ Hope you and your fish are well. Please help me make up my mind. I'm going to be adding pump fed trickle filter on my pond, measuring 45"x35"x24". The pond wall is 50" high, so I need the stand to be just over 50" tall. Two options as I see it, Make one out of 4x2 treated c24 or dry solid concrete blocks, 440x215x100mm. Would I be able to make at wooden stand out of 4x2 strong enough and stable enough to hold a weight of 2-300 pounds at 50" high? The amount of blocks if I have worked it out right would be 156 blocks. So that consists of 13 layers x 12 blocks for a 45"x35",to sit on, standing 52" high. Thank you

    my 1000mm x 400mm trickle filter is standing on a frame made from 4" x 2" CLS (nearest in mm 89mm x 38mm?)
    and has 11 boxes of CSM in it. weighs a fair old bit

    it is screwed to the walls to stop it moving, but the strength is plenty to hold the weight.

    Hi Dave / Thank you . It's going to be outside. Would you do wood then? I would cover it with tarpaulin to keep the weather off it. Yes nearest to mm 89x38mm. Was thinking of making top and bottom oblong connected by four uprights, if it makes sense? And connect them with 45 degree brackets. Thank you

    showers need air to gas off the ammonia, i wouldn't cover it exept in winter to cut down on air cooling.

    brick will be more stable, depends on cost hassle?
    for wood i'd use pressure treated timber, a solid concrete base, and fix it to the side of pond wall for stability,
    as high winds outside in winter and a wide shower can make a big domino fall

    Hi Dave, Sorry I should have put cover the wood and not the filter. That's the one good thing about my trickle filer. It's 30 years old and made of fibreglass. And the water is pump fed into a 15,20gallon bush chamber. The water then rises up through the brushes in the chamber. At the top of the chamber there are three 1.1/2" spray bars sited across the width and length of the filter. Which the water percolates Through 100 litres bed of perlag pea size media. And return through a 4" outlet back to the pond. So the filter as a low centre of gravity and is very stable. It's just the height of the stand itself, were there a concern, So the stand would have to be just over 4 foot high.

    Thank you Dave if I screwed it to the block wall it would be solid. The only weak point would be the frame work it's self.
