    they both function the same, one takes more space than the other, i use skinny as i dont believe in drilling the base of a tank

    Thanks Dallas, what size pipe do you use for the over flow? Do you use a bean animal or the likes there of

    i use 50mm for drains and 32mm for returns on larger tanks, for smaller 400L or less i use 32mm drains and 20mm returns

    i am looking at DIY'ing a XAQUA overflow

    Thanks

    I am in the process of building a new tank and its about 385 litres so I guess a 32 mm drain will be ok?

    Do you have any images of your overflow?

    wow that is rather tin, do you have any issues with fish getting in side? Do you just use a direct syphon on both pipes?

    I got this on my previous tank

    Had a small clown fooling around and ended up trapped in the overflow box. The clown got caught between the bulkhead and front glass.

    Just blocked the outlet at the bottom to flood the overflow box, giving the clown an opportunity to escape. He did survive.
