The biggest trap in buying toilet tablets for hard water is grabbing one that dissolves in days instead of weeks, leaving you right back where you started with mineral rings and wasted money. You end up cycling through cheap tablets that barely outlast a long weekend, while hard water stains quietly cement themselves to porcelain you thought was being cleaned. The difference between a tablet that actually prevents buildup for months and one that just tints your water blue comes down to a few specific details worth comparing.
