Turns out bleach is notorious for tearing up rubber.
I guess you learn something new every day, huh? Hopefully all you Blumat users will take note of my dumb ass mistake and learn from it too.
I tried popping the pieces of the top apart to get to the rubber, but couldn't get it done. At least not easily. Hopefully this hydro store still has em in stock...
I wonder if there's some way I can put a filter into my system that will not clog it up.
For sanitation purposes, I'd use an oxidizer. LeeROI mentioned Hydrogen Peroxide, and a straight 3% solution
That is the shit's, Marlo. Did you do the bleach thing before you stored them or when you were getting ready? I thought maybe if they hadn't been thoroughly rinsed the bleach might have gotten to them?? Anyhow, check out the following link at Planet Earth - I just ordered another patio kit from them a while ago, and they not only had the best price I could find and free shipping, but I got them in a couple of days. Good luck.

PS - have you checked the Tropf Blumat site to see if there is a service part for the broken piece?
