Blu52 product is not the same!!!

I have been using Clear 4 weeks and now Blu 52 for many years and never had any complaints but for the last few months the chemicals in the booster week divider (central container) have gone solid as if moisture has got in. I opened a twin pack, brand-new from the store and the same thing has happened with both containers. I had to use a *****driver to loosen it before I could pour it into the weir. Our pool is also very cloudy after swimming. This has never been an issue in the past. I can not get hold of the company to direct my complaint to the correct person.
