myusernamerocks,
The reason I ask if the neck in the cup is getting muddy all the way through or from the bottom up only so high, "but you are not getting any skimmate the cup is this:"
Sounds to me like your water level in the skimmer is way too low! Raise the level up by adding water to the tank or adusting the overflow box if you have one.
If you do not have a overflow box i would recommend getting one for sure. Then start marking the water level in one of the sump boxes with a piece of masking tape or electrical tape.
Monitor the level and note the changes to the skimmer production in the cup. Continue to raise the level until you start getting skimmate. Then fine tune the level to your desired color of skimmate with the overflow box and or water additions to the desired level.
This certainly was a design flaw or should I say "barbarack" design on teh first model. However, the overflow cup in my opinion will certaily change this immensily!
I have saw pics of your skimmer pull out some good gunk! It's all a matter of getting that water level just right. The overflow box just makes it easier, and the new viewing level winder is the iceing on the cake for the new model!
The tape or mark on the back will substitute the water level eye we hav eon the new model.
I think if you do this, you will not need to spend the money on another skimmer. The original skimmer may just be fine.
DO YOU AHVE ANY PICS OF THE BUBBLE OUTPUT FROM THE SKIMMER THAT YOU CAN POST?? That would be great and I would love to see some pics!
I hope this helps
