    i just recieved a tank from a friend that used it as a freshwater tank but it has been standing emty for a while now. it is a standard 60cm tank you buy at the lfs. water gets pumped from tank to sump and goes into chamber A, water goes through skimmer there and then goes over DSB, the dsb's footprint is double the size of the tank its for. the sump will sit above the tank because it is a nano baught from a shop and u cant drill the glass because its hardened. all in all it should ad about 50 liters to the little nano.

    would this work? any comments welcome

    I can see no reason why this would not work. If this is kind of to scale...then is there gonna be enough space for your skimmer in the 1st chamber?

    if i can get the correct fittings there should be no problem at all, i measured it with the glass in the tank just laying there as well as with the skimmer the only thing i didnt realli test is if the overflow will be fine

    That over flow may just be noisy.. I would possibly add another "baffle" in chamber a so the flow from the DT is "under" then "over" the dsb. as it is now its just over the dsb?!?!

    yes, i want to use a elbow in the overflow to make that the water will be just under the overflow so less of a fall distance, as for a baffle i cant do that because i need as much filtration as possible and that takes space but thats just my opinion, i think if its to noisy i will have to do that

    You want to keep evaporation in mind. A Small return chamber like that will empty very quickly with evaporation. If you were using an auto top up it might help, the pump will becoming on often for a few seconds everytime.

    I have considdered an auto topup but i have decided against it because of space issues. Will it help if i were to say cover the over flow more or less

    You want biggest footprint for DSB

    Remove return chamber.

    Drill the hole for the outlet, put your bulkhead on, on inside put a 90 degree elbow facing up, short piece of pipe to water level. Can put a Durso, or soil vent valve on the top to silence it. So it stands out from the DSB.

    But you will have to get an auto top-up as Dohn said.

    What will happen is the water level in DT will drop, and if that works with a overflow method to a chamber at the back to the pump, the overflow will stop. Pump will run dry. Else if you can have water level flactuations in the display tank. The auto topup will not be that big an issue.

    Ok now i get it no water fluctiations are not a problem four liter can evaporate before u can even see it and then another four will still be fine before pumps start running low on water, i like that idee riaanp im going to look into it

    an auto topup is ESSENTIAL for a skimmer to run effectively without it you skimmer will never work 100% for long !!

    Hi Riaan,

    With Most Skimmers, the water level (i use the TS range as an example) is controlled by an outlet pipe, the higher you raise the pipe, the higher the "bubble popping level"... however this method of controlling the "bubble popping level" is directly and unavoidably linked to the water level in which the skimmer is placed (as such an external skimmer is excluded from this problem)...... A drop in a few mm will effect the efficiency of the skimmer .... amazing that a small change can affect the skimmer so much but trust me it does ! .... In my system i regularly loose 9L of water a day through evaporation..... which equates to a fall in sump level of up to 2cm ....... if i did not have an auto top up keeping the level constant, my skimmer would start out skimming at the right setting and by the end of the day be skimming so dry, it would be doing bugger all good...... hope the explanation makes sense !

    Johan - I too think that this will definitely work for you. You need to go to specialist irrigation places. They would/should have the bulk-heads you are looking for, to fit the hole in the glass.\

    How many mm is the hole in diameter?
