Query: Both bags broke after day 1

I bought these based on the positive reviews, however my experience with this product is a messy nightmare in the pond. Both bags I used that contained the straw broke after 1 day in the pond. The mess was unbelievable and tedious to clean up. I recommend staying away from this product at all costs if you actually want a CLEAN pond. This was awful!
