Need help bad

[Firstimepool]

Just moved into last month with above ground pool. The pool turned green and I tried to tackle it before it got any worse but nothing worked. Now it has a thick layer of algae on top and I have no idea what to do. I’ll attach photos if I can I am new to this forum

Get as much out as possible with a net and then Slam (Shock Level and Maintain) with relation to Chlorine / CYA Chart and Recommended Pool Levels
Use Pool Maths to work out what quantity to use. If you get stuck come back with details an we will help
Get your water tested
Let's have your numbers especialy CYA
Excessive CYA renders your chlorine ineffective and you have to use more to get the same sanitation
For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm.
For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm.
For every 10 ppm FC added by Cal-Hypo, it also increases Calcium Hardness (CH) by at least 7 ppm
To reduce your CYA you have to do a partial drain and refill
FC:
TC:
pH:
TA:
CH:
CYA:
Use these common products to balance your pool
Liquid chlorine (sodium hypochlorite or plain bleach)
Muriatic acid (hydrochloric acid) to lower pH and TA
Bicarbonate of soda to raise TA
Aeration will raise pH only
Soda ash will raise pH and TA
