    As a general rule of thumb, the outflows must be twice the diameter of the inflows if you are using a gravity feed. At this point the only solution is to reduce the flow rate or split the water flow so that some of it is pumped directly back into the sump. This can be regulated by fitting taps on the split to manage the flow rates.

    There are too many imponderables . . . The pumps are supposed to have input filters, and the overflowes are to be fitted with sponges to frevent fish from disappearing down the pipes.
    The sponges will increase the height of the water further, but the filters will reduce the power of the pumps.
    At the moment, the whole lot is operating without any of these restrictions, although i didn't think that it would be this bad.
    The pumps are definitely over-powered (2 x 35W "King-3" Resuns). I'll have to do a bit of "moderating".

    Greystroke why not run the water through copper tubing over the heat sinks that way there is no risk of flooding?

    I wouldn't run the water through copper. Not if the water runs back into the fish tank. Especially if Crustaceans become leagal, and if you like your snails.

    Would the copper not be fine at a higher pH than a CO2 tank Sean, all our house water comes in through copper tubing in the newer houses if the copper is a problem then go with stainless steel.

    What about the aluminium that the water runs over?

    Copper, as far as I know, corrodes when in an acidic medium. So in a planted aquarium, which is usually acidic, it will not be good. Even small amounts of copper are bad for inverts.

    That's why the water board is supposed to treat the water to be a pH of 7 and above, so it does not corrode the copper piping.

    Coper is also bad for fish gills..

    Stainless steel is cheap in South Africa, R300 for 6 meters.. so why not use it instead?

    Its cheap because it doesn't stay stainless for long... You can find 30-40 yr old stainless steel which is still spotless. Good luck finding stainless steel a few years old which is still spotless.

    +1 go to a stainless steel supplier and ask them fore 316 grade stainless steel. It is so called marine grade stainless. Don't know the spec of the stainless you referring to in regards to size and shape but I would think you would be very surprised of the price of good quality stainless. Then there would be the factor of somebody making up the tubing. Not alot of guys van weld up stainless properly. So the one's that can charge a hefty fee.

    It is the result of this "thinking" that is usually the most interesting. :thumb:
