PRO TIP
Never force the locking tab if it feels stuck. Usually, this means the lid O-ring is dry or misaligned. Re-lubricate the O-ring with a silicone-based lubricant to allow the lid to sit lower, making the tabs much easier to lock.
Always follow label directions and safety guidance. Keep pool chemicals and accessories stored safely and out of reach of children.
