I have been buying Scumballs for 5 yrs now. Two purchases ago I thought I received a "bad" batch, they were not "flocced" like the ones prior, ya know like fuzzy, they were just "spongy", so this time I ordered again, BUT NOPE not a bad batch last time, totally changed scumballs. I do not like these "new" type I do not feel they attract the "scum" like their earlier version did, which by the way I still use, instead of the new ones.I won't buy again. Mind you no reflection on HOT TUB warehouse, not their product any maybe they did not know they change....The pic shows the old fuzzy on on the left, the new smooth one in the middle, the brown one is the new one after 1 day in the pool, turnes brown & the holes are large like sponges.
