Trichlor pucks are tablets that people either put in a floater or in a chlorinator. Dichlor is a powdered form of shock.

It can take a lot of bleach to clear a pool. The reason your chlorine level won't stay up is because it is being used up killing algae. That is a good thing. As many times a day as you can test and add bleach, all the better and it will clear it that much faster. Try and keep it at 15 as best as you can.

What is your pH reading? (Don't check pH when the chlorine is high or you'll get a falsely high reading.)

It is a headache ................ but it will clear! Just keep picturing that clear pool that you'll soon be swimming in! Hope this helps!
