    Has anyone built a sump inside a standard 4 foot tank? If so, please send me pics of the design and layout :)

    have not done so on a standard 4 foot but have had a few 4foots and built a few internal filters so will try help.
    on a standard 4 foot there are normally 2 braces 50mm wide on each end and 150mm central brace witch will mess you around.
    based on this i would choose one side in between the center brace and end brace. think it will give you 500mm buy 400mm deep space witch will work out great. Try make 4 chambers ideally 100mmx120mm so it is easy to get your hand in to clean. try buy glass from someone who can drill the glass for you, inlet 50mm outlet 20mm.
    hope this helps

    Thanks Top Dog.

    I appreciate that. Could you maybe draw a birds eye view in pencil drawing? I need to see things for it to make sense :)

    Do you mean something like this?
    An internal filter?

    I'm a bit confused. Are you asking if you can build a filter inside a 4 ft tank - or are you wanting to use a 4ft tank to make a sump for a bigger tank? I have a 4ft sump for my one tank but it's a 1000 litre tank. Is that what you want to do?

    Thanks, @top dog. Only problem is that the bracing runs the length of the tank, front and back. Not the sides.

    How about this? Heaters hidden behind the internal filter and return pump pumping out water from the filter next to the heaters to ensure even heat distribution throughout the tank.

    should work well
    ideally have a larger pump for 6-10 turn overs per hour
    250ltr 1500ltr per hour as a min
    would make sure you make it large enough to fit pump in and easy to get your hands in to clean
    heater placement is not great, if you do want to hide it in the corner would place a airstone on that side as well

    So I worked on a better design for the filter to as to increase space and improve the look inside the tank.

    I have designed it in such a way that the top bracing won't negatively affect my ability to get my hands in and out of the filter.

    The 30cm baffle for the heater chamber will allow for my hands and arms to reach in. The 17.5cm space in the return pump chamber makes for space for upgraded pump :)

    The middle chamber is for filter media which I will place so that the sponge comes out easily and not interfering with the biological filtration.

    Let me know what you think.

    Much better placing of the heaters, like that you dont have the risk of the heater compartment running low due to the sponge blocking up a bit
