OK. Look forward to seeing the pictures.
With regard to the algae, the shock treatment is a temporary fix. Once we understand the valve set up, we then need to move to doing a
SLAM Process. That is the only way to rid your pool of algae. You need to be prepared to purchase a lot of liquid chlorine. How many gallons is your pool?
This all started out to help identify valves and we are nearly there once we see the pictures with the pipe marked. Now we need to make your water crystal clear. Did you see the contributions from all the members in this months contest on water clarity? It is the first post on the New Content under forums. We can get you there.
Also do you have a proper test kit? You will need one for the SLAM.
