green pool water

Help, my pool water is green but all of my numbers are within range. Two weeks ago I had to change my pump so my pool went green. Since then I have shocked and the pool started clearing up then went green again. I have been to 3 different pool places have no idea what to do.

My numbers are as follows: Free chlorine 4, total chlorine 4, calcium 280, cyranuric acid 30, alkalinity 90, ph 7.6, copper 0, iron 0, total dissolved solids 900, phosphates 0. All within the levels that the pool places say.

my pool does get direct sunlight all day and the temperature can rise to 90 because of this. Do I need more chlorine because of the light and temp? I do not have a heater.

Thanks if anyone can help it would be appreciated!

You have an algae bloom and need to Slam follow the instructions exactly
How are you testing? You really need a good test kit to be sure of your numbers (Taylor K2006c or TF100) and are putting the right amount in
Your numbers seem OK but check out these links
