Running a Reef Glass nano skimmer that utilizes a limewood airstone. It actually pulls out some incredible gunk......when it works.
Here's my issue and I am running out of ideas. The skimmer will bubble fine for awhile, then you'll see all the bubble stop, a second or so later a huge surge of bubbles rush out, pouring from the bottom of the skimmer out and shooting the bubbles up, then it will settle and skim great for a bit again.
I've adjusted the height numerous times, trying to find it's happy spot
I replaced the airstone
I replaced all the tubing
Shortened the drain tube
Removed the intake valve and using an adjustable airpump to control flow
Removed the drain tube entirely, STILL DID IT
I thought maybe the exit/return tube was getting clogged. Without a way for the air to escape, bubbles wouldn't be formed until enough pressure built up and it got pushed through. That's been the theory I've been trying on this, but removing the drain tube entirely and still seeing it kind of nixes that.
Anyone else ever run into this? I really don't want to go to a needle wheel, it needs more room than I have available. I'd go skimmer-less before I went that route. Since the bubble column never really stays formed it's not working very effectively. As well as you can hear the bubble release periodically as they rise to the surface, so it's kind of annoying when you work from home and it's right by you.
Thoughts? As always, appreciate any info
