I've been wanting to mod my 2+ year old EuroReef CS6-1 for a while and finally got around to it last weekend. It only took about 20 minutes and I am impressed with the results. I bought a Sedra 2500 with needlewheel and venturi (to be used as the recirculating pump - the original Sedra 3500 is still feeding the skimmer from the sump) and used a 1/2" Uniseal (output) and 1" Uniseal (input), 1" elbow (venturi fits right into this) and drilled the appropriate sized holes in the skimmer body. Sorry I did not take more pictures of assembly out of sump, I was too excited and short on time to take pictures. I will try to get more photos next time I clean the skimmer.
The first series of pictures below shows the foam production after a couple hours. I had to remove the riser tube from the socket (where water exits the skimmer) or the collection cup would fill up quickly with clear water. Once I removed the riser pipe, you can see the bubbles in the reaction chamber, neck and cup.
The second series of photos in the second post below show a couple days skimmate after the skimmer settled in and I was able to add the riser tube back at its lowest setting. Pretty nasty stuff considering I only feed every other day and only have 5 fish in my 100-gallon tank. I think the only thing I am going to change is to remove the union on the output side as the output side of the pump fits loosely enough in the Uniseal that I don't need the union to remove it. This will allow me to put the pump closer to the body. I don't mind the distance now as I have room in my sump, but for those of you that try this, just know you don't need the union.
