    I want to replace my old school Aquamedic shorty skimmer. Maybe my backside is just itching, but maybe worthwhile to change. My bioload is increasing slowly, as the fish grow. I do want to add a number of smaller fish as "fillers". Popping in and out the rockwork.

    Anyway, here is the requirements.

    • My display is 750L, so looking for something up to 1500L/h skimmer.
    • Internal skimmer.
    • New or secondhand
    • Energy efficient pump/s
    • Footprint space available / first compartment size 340X620mm
    The catch

    Height space available ismaximum 620mm. That means I need to get the cup off within the limit of 620mm. 600mm will be better.

    I checked out 3 units so far, and out of the 3 already have a favourite. Unless somebody can suggest an alternative within the space limitations.

    This is not only a sponsor request thread or a "wanted" thread, but firstly a "gaining information" thread. Maybe at the end of the day I get a short stick to scratch my backside.

    Hi, I'm in the same boat, also looking for new one.

    Have you looked at the Tunze 9415, I'm considering getting one, which other skimmers are you considering?

    Riaan why not move your skimmer to your sump room, plump an external one in, you have the space and could go for a lekker beast.

    Tunze 9415 doc skimmer is only 440 high, the cup comes off with no effort at all unlike my reef octo 5000 int, I would go for tunze 9415 doc skimmer.

    But if you have the space to go external why not do that instead?

    how much space extra is needed to remove the cup? I see its 530mm high so I do believe It will make the 620mm height restriction

    Not yet, Seen the new Aquamedic, Reef Octopus xr3000 and Bubble Magnus curve 9.

    I can, but not all the water goes to the fish room. The return splits the flow up to display and fish room. So ideally the skimmer should stay where it is currently.

    Sump is maximum under the tank.

    That should give you an idea of space in sump area

    Take a look at the new Bubble magus curve skimmers (probably thwe curve 7 or 9)... They look rather nice; I had a look at BrettB's new curve 5, a very well built skimmer that looks like it can do the job!

    i would also look at the new range of Deltecs, you simply dont go wrong with them.

    i have the ATI 250i in which is a good skimmer, but doesnt touch what my old deltec can do.

    alternativley pop round @Ridwaan he has 8 second hand skimmers to sell, if not 8 certainly a few, ive never known him to cycle a tank to completion or not have awesum skimmers in his garage! :)

    yip, did check out the 9. And admit, seems like a rather nice skimmer. So far it is at the top of my shortlist.

    He must have experience in each make of skimmer. Awaiting his comment. :)

    I would look at a Deltec TC2060 if finances allows

    or I would put another Shorty next to that one

    not in the same class as a deltec TC2060 and only slightly cheaper.

    the SC2060 is better. Internal and no extra feed pump required.
    Although the TC2060 that is external can be fed directly from the overflow.

    Can the TC2060 be installed internal?

    Who supplies these?

    and my sump skimmer chamber water level is 307mm deep. Can not lift the skimmer if needed due to height restriction.

    it will still need a feed pump though for optimum air intake of the recirc pump.
    The TC stands for twin chamber. So if you look at the bubble plate section on the skimmer, its divided into two, the bottom part is where the raw water is pushed intot he skimmer and is also the place where the recirc pump pulls water from. THis chamber is completely sealed and works under pressure.
    So your feed pump will actually force water faster intot he recirc pump, allowing the recirc pump to pull more air as the water is forced into this section and forced into the recirc pump.

    The recirc pump then pushes water/bubbles intot the top part of the bubble plate which then gets skimmed out.

    The SC2060 is a single chamber insump skimmer so no need for the second chamber.

    I would say that the TC 2060 can be fitted insump without a recirc pump as the recirc pump will then draw water from the feed section of the chamber and the feed pump chamber will then always draw water directly from the sump through the feed inlet. But then again the recirc pump will pull less air...

    I might be wrong and confused myself there...LOL!
    @Nemos Janitor , please correct me if I am wrong...

    OK, Deltec outlets too low
    TC2060 (Height under outlet pipe 281mm) and SC2060 (Water level in sump - 180mm min 260mm max) \.
    And the SC1455 (Water level - min. 140 mm / max. 240 mm)

    Same for Buble Magus Curve 9 (Water Level :9.5"-11")

    Did not take that into account... There goes all my first options down the drain.
