I had a salt water pool put in last summer so bear with me as I'm still learning on what I need to do to maintain the pool. Right now, I'm seeing some type of "beetle" swimming around in the pool. Is there some way to get rid of these little buggers. I've had all the levels checked and all's good on that front. I've had someone tell me to add bleach or some chlorine tabs but I'm not sure if that's a good idea. I live near Phoenix, AZ.
