My CYA is >100. I don't even make it within 1/2" of the mark on my Taylor test kit before the black dot has disappeared. I opened the pool 2 weeks ago to a green mess, I couldn't see the deep end. I shocked it with Shockwave 73%, 4 lb worth of it over 2 days. The pool was ready to swim in a week later. I tested the water and verified the CYA test with the local pool store.
I would like to drain it, but can't figure out how. I can get the water to pump out of the bottom of the filter without a problem, there's a hose bib attached there. Once the water is below the skimmer I start blowing bubbles and lose flow. At the bottom of the skimmer is the connection from the drain. There is a simple valve which covers the two ports so water only moves between the pipes and not from the skimmer. The pump pulls water at varying rates, sometimes coming to a stop. How do I drain the water without fear of hurting my pump?
Please see the attached pictures of my equipment. There's no discharge to bypass the filter or heater I have to pull the water from the filter drain.
