This morning before I left for work the collection cup on the 160 was about 1/2 full and the foam head was a little lower than the night before. I reasoned that the 10 gallons of water in the tub had been skimmed thoroughly and I needed to add more fuel for the skimmer. I proceeded to empty my skimmer cup from my display tank into the tub and I took off for work.
This is what I came home to -
I guess dumping a ton of skimmate into such a small volume of water caused the skimmer to overflow, subsequently emptying the 1/2 cup of skimmate from the SWC into the tub as well.
The end result is a GIANT RED TUB SKIMMER. I better hurry up and patent it before some other company steals my idea
Lesson learned....you can add too much of a good thing to the break in tub! Now I'm left to do a water change on my skimmer break in tub....good grief.
