tHEcONCH Posted March 4, 2008 Author Report Share Posted March 4, 2008 So, here is the weir-derived overflow and return for the RSM. The intake pipe draws water from the passage under the skimmer, up and out the chiller port, down and up again to the air vent, then across and down to the sump. Return comes up and across the top of the vent, through the chiller port and under intake, and deposits water into the circulation pump intake. It all fits flush against the back of the tank.

wasp Posted March 5, 2008 Report Share Posted March 5, 2008 Nice work! Don't see why you found it did not deliver enough water? Link to comment Share on other sites More sharing options...
wasp Posted March 5, 2008 Report Share Posted March 5, 2008 All I think it MIGHT need would be something to ensure the intake did not get blocked, such as, say, a secondary intake, or similar. But I think it is a great example of a weir overflow. It's so good I'm actually going to talk to a mod & suggest we get somewhere things like this could be put on the site permanently for people to see.

tHEcONCH Posted March 5, 2008 Author Report Share Posted March 5, 2008 I had the airvent/crossmember too high - I set it at water level, now I've dropped it 8mm down to break the surface tension more easily. I'd wondered about the intake too - I might stick an Eheim intake end on it (I think they are 16mm ID cf the 15mm tubing, so they should be able to fit Link to comment Share on other sites More sharing options...

tHEcONCH Posted March 5, 2008 Author Report Share Posted March 5, 2008 Oh Sapphire, I only built one of these - the materials cost nearly $100, so you are welcome to measure it up before I fit it if you want to build one too Link to comment Share on other sites More sharing options...
Sapphire Posted March 5, 2008 Report Share Posted March 5, 2008 Great Conch! I am keen to grab some measurements etc so will organise that with you. When are you going to fit it? Link to comment Share on other sites More sharing options...
wasp Posted March 5, 2008 Report Share Posted March 5, 2008 Well if people are going to be making these I have a couple of pointers. The bit that slows the whole thing down is (as Conch said), the cross piece by the airvent. The lower you set that, the faster it will allow water to flow though. But, the lower you set it, the lower the water level will fall to in the tank if there is a power cut, meaning you need that much more capacity in the sump. Just tee-ing the cross piece up to a larger size pipe will allow faster flow, meaning the cross piece can be set higher. The other thing is I really REALLY think a secondary intake pipe should be installed, or lots of holes drilled along the intake pipe, or similar. This is because the current design has just one intake hole, exposed and in the tank. More likely when than if, it will get blocked. Could be a dead fish, or whatever. The return pump from the sump will then dump water all over the carpet as the tank overflows. The other thing could be to install a shut off switch to the return pump, should the water in the tank go higher than a certain level. Link to comment Share on other sites More sharing options...

The other thing could be to install a shut off switch to the return pump, should the water in the tank go higher than a certain level. I think that is probably true and good advice for a normal tank where the intake is inside the main tank, but don't forget that this one is specifically for the RSM and draws water from under the skimmer chamber, which sits behind the 'false back' of the tank behind the intake / overflow grill. In addition to the grill, there are also media bags (and for those running a more standard configuration) mechanical filtration blocks. That said, perhaps cutting the intake on an angle of drilling holes / slots would be cheap insurance, just in case. Link to comment Share on other sites More sharing options...
wasp Posted March 5, 2008 Report Share Posted March 5, 2008 Oh i see. Taking water from inside that chamber will work well. Link to comment Share on other sites More sharing options...
tHEcONCH Posted March 5, 2008 Author Report Share Posted March 5, 2008 Further to your idea about some sort of resource / area for this sort of thing, should I take some other photos that show just the overflow before I fit it up? Link to comment Share on other sites More sharing options...

tHEcONCH Posted March 5, 2008 Author Report Share Posted March 5, 2008 Although there have been rumours of a 250litre version as yet there is only one size - 130litres - and they retail anywhere between $1500 - $2000. Link to comment Share on other sites More sharing options...
