    Dude if you siliconed that overflow box on it will be secure enough, you needn't have to worry.

    Those holes look a bit small for the overflow on that size tank, what size are they?

    Pipes are too small, that's an inner bore of approx 20mm.
    Go at least 2 inch, then use valves to throttle the flows.

    On the wheels, I personally wouldn't do it.
    Check the load ratings per castor wheel, even if safe, the rubber will flat over time making them difficult to roll. Frame and tank will need significant gusset to handle the loads created by the water swaying as you move the system.

    Just checked, I used 32 mm pipe work on my overflow.
    Check my tank thread under the Supersize section if you want to see pics of my set up

    wheels are fine I've had a tank on wheels for the last 2 years, the sump was inside the same stand on the wheels too, so about 700 liters of water spread over the 4 wheels, just make sure they have a locking mechanism. SA Ladder sell plenty wheels that can handle the weight, even cast Iron wheels of a similar size that can handle almost a tonne each.

    Iam not sure about how strong they are but I think each one can carry 250kg so total weight will be 1000kg ... I am going to make static legs that can be adjusted in height that when I fill the system and put it in place I will make this legs carry the tank and once I wanna change my home that's will be maybe after 2 years I am gonna use the wheels that's all and if you have picture for your wheels I will be happy if you share it here

    [​IMG]
    Green Nut
    Blue Wheel
    Red Bolt removed the Bolt head
    Light Purple the base of you stand(Portion that sits on the floor if you had no wheels)
    Orange Good washer

    The red Bolt is welded as per below pic to the wheel.

    The red bolts slides thru a round tube that has been welded onto the frame, the red bolt is in no way attached to your frame, only by the weight of the stand/stand/sump pushing down on the washer, the green nut is therefore used to adjust the height of the tank and thereby you are also able to adjust the level.

    Hope this helps a little.

    it is tricky to get all the wheels under on the first occasion, this is best done without the tank or sump in place, so just the stand. Please make sure you have a really skilled welder to weld the bolt to the wheel, there is no weight directly opposing the welding of the bolt to the wheel, unless you plan to move the tank by using the wheels, try get wheels that offer you a little impact resistance and when moving the tank and sump full of water make sure to do it slowly and avoid any stand wobble.

    PM me if you need further info.

    Why do you want to put your tank on wheels?

    Really if I wanna change the place but it looks like its a bad idea after I calculate it now I have two option first to remove it and this is hard cuz its expensive and its already welded secound to install 8 legs that can carry the system and can change its length
