So I went to two different pool stores and got completely different answers and I still have NO idea what to do. Someone please help me!

Store 1- They said it looks like algae but they don't test for algae. He told me to shock, pour in a bottle of algecide, shock again, vaccum. He was about 16 so I went for a second opinion.

CYA 93
total chlorine 8.5
free chlorine 8.5
ph 8.2
alk 214
hardness 245


Store 2- Said it's iron and my ph is too high. They said use iron out and acid

CYA 29
fc 10.88
tc 11.76
cc .88
ph 8.4
alk 188
hardness 258
iron 5.2
total dissovled solids 900
saturation index 1.1

So same pool water, taken at the same time, very different results and totally different recommendations. Someone please help!!!!
