We got our pool fixed with new liner and new water. Realized that the motor is bad when it was ready to start. Trying to get a new pump or getting this one fixed ( which is taking time). I let my kids jump in it just once as not very confident about adding chlorine in the pool without the pump running. How can I prevent the algae to build up. I try to brush it once a day and manually remove the leaves and other debris from the top with a net. Please advice any more things I can do to keep the pool clean.
