ASM Skimmer help

[spjeff69]

I added some rock to the new tank finally and I knew the skimmer would go crazy. However, instead of filling up with dark skimmate, it fills up with bubbles?!

How do I fix this?

you just need to adjust your riser tube (round with the black foam around it). Slide it down until the bubbles aren't rapidly overflowing into the collection cup. Have the lid off the collection cup so you can see the skimmate adjust. HTH

Check the air tubes, too. I shortened my standpipe and cleared the airlines, it quit going nuts.
