Does it always foam into the collection cup or does it sometimes go right down???

Do you mean ? The foam, your asking if it is always foaming? No it will stop for small amounts of time. When I have an additive (chemi clean) it goes nuts for about three days none stop big bubbles I'd have to dump the cup every min or two. That would be why I modded the unit, I actually add the turbofloater 1000 and run both. Does that answer your question?

Well I have the air full at 12 o'clock and my cup is far down and there is no foaming action in the cup????? That seems not right to me because my previous skimmers foamed all the time. Also when it was foaming the foam was never brown looking it was just a clear foam???

Think about it... a better skimmer should be more efficient or better at pulling DOCs out of the water. Otherwise, why would it be better? If Coralife skimmers worked as well as Deltec skimmers, I would think D-D would be out of business. So, when upgrading to the much more efficient Deltec, you made a change where you can now pull more and possibly different DOCs out of the water, DOCs that your old skimmer didn't have access too for whatever reason.

Try hooking a skimmer up to a tub of your tap water, I guarantee that skimmer can pull something out of the regular tapwater before it even goes into the tank. I watched someone do this in Saskatoon and was disgusted by what the skimmer pulled out of plain tap water.

It skims best in-between, not when it's open full. Close it. Then when you open it, it will get a little loud. Keep opening it little by little until it quiets down a bit- that's the 'sweet spot', the place where you'll pull the best foam.

Could someone please tell me how to remove the pump for cleaning?

Does the media holder inner plate thingy need to be used if no media is used, so I can put my heater in there?

Thanks

Just slide it to the left, then pull it straight up. If it gives you grief while you're restarting the pump, you'll need to play with how far you push it onto the fitting.
I never actually bother with rinsing my pump... lol. I do drip warm water down the air valve once every couple of weeks, though.

I always thought that was there just to keep the media from floating upwards and blocking the outflow.

Thanks.

Mike, the fixer upper guy, :D , figured it out. All cleaned up and repaired. Now I owe him, but he,s going away again soon, so will take care of his tank. :lol:

Its actually a fair sized skimmer.

Does the degassing plate do its job? Mine came without one and we are thinking of building it. I seen a thread where some said they just removed them? Or perhaps just using a couple 90 degree elbows?
