Don't let the phrase 'pool chemistry' scare you. Taking care of you pool/spa water takes very little effort as long as you do the following:
Test the water regularly -- Checking the chemical levels in your pool or spa on a regular basis may seem like work, but correcting problems in a pool or spa takes a lot more time, will require a lot more chemicals, and costs a lot more money!
Don't skimp on the chemicals -- It will cost you more money and mean using a lot more chemicals in the long run to solve an algae problem, clean a stained liner, etc.!
