After my skimmer trouble I did what some people suggested and made it that my skimmer ran though poly fiber to eliminate the air bubbles. Well I have a piece of 2" pvc that the skimmer water goes through and while changing my fiber tonight I noticed I had hundreds of pods in the tube. I had to pull all the fiber apart to get them all out and back in the tank. But then I thought gee next time I change fiber I will put the old fiber in water and see if any one needs some pods for ther tank or refugium.
