Thanks guys. I think I will go with the Octpus 800S then. Does anybody have pictures of itin use, hanging on a tank? It looks complex to me...
Also, what modifications are you guys saying needs to be done to it right out of the box?
It is not complicated to setup. The hardest part is getting the siphon started the first time. Short version: Connect air hose from the pump to the valve on top of the input tube. Fill skimmer with saltwater. Install collection cup and set at highest setting. Plug in skimmer, as soon as it starts pulling water from your tank shut the valve on top of the input tube. Remove air line from shutoff valve. You will now hear a loud sucking sound. Install the included muffler to the air line. You are now done. (well sort of)
When the skimmer is new it will skim VERY wet. This is normal of all skimmers until the surface contaminates are removed. You will need to empty the cup a lot for the first few hours so have some saltwater ready.
You should leave the cup as high as you can for the first few weeks. The skimmer will go through a break in period before it settles down and becomes stable. At that time you can lower the cup a little at a time to get the desired skim consistency.
You will see a little seepage around the seal of the cup for a few days. This will stop as soon as the skimmer body starts to slime up a little.
Now for the mods: I got kinda serious about this part and not for the non do it yourselfer. I drilled two holes between the reaction chamber and the first (input) chamber. This allows the skimmer to act as a recirculating skimmer. The flow through the skimmer will be less giving more time to remove the proteins. Another benefit is total elimination of micro bubbles. Then I mesh moded the pump. This causes the skimmer to really come alive. The bubbles are extremely fine and many of them.
Here is a picture of the two holes.
Here is the collection cup about the second or third day on the tank.
Both of these pictures are before mesh moding the pump. The foam is now more dense.
When I get time I will get some pictures of the skimmer with the moded impeller. It generates nasty dark green goo that stinks really bad.
