Algae Problem

[Casurf21]

Okay so a new pool person here. Renting. Landlord has a pool guy who comes weekly. He pours stuff in the pool. Never see him test. Has been months. The pool is GREEN. Tons of algae. Some brownish/black algae. The water was clear. Bought my own test kit and CH level looked like 0.0 visually and pH looked like 7.7 visually.

Leslie's water test results:
Free CH 0.08
Total CH 0.22
PH 8
Total Alkalinity 106
Calcium Harness 162
Cyanuric Acid 27
Iron 0
Phosphates 290
TDS 800

I cleaned the sides of the pool with the wire brush. Now the pool water is completely cloudy green of course. Filter has been running. I shocked it with 5 bags of Leslie's Power Powder Plus 73. It is 27 hours later and the pool CH level still looks like 0.0 or maybe just under 1.0 visually. Still running the filter. Pump is 1 HP and the filter is a Pentair FNSP 60. Will have to clean the filter later today probably.

Pool volume roughly 30,000-36,000
Is a weird shape. 35' long at its longest points and 23' wide at it's widest point. Ranges from 3'-8.5' deep roughly.

Help? I don't want to keep shocking. What are your recommendations?

How about asking the home owner if he'll deduct the cost of the pool boy from your rent? I *know* that you could do it better for far, far less and with far, far better results if you let us teach you. You'd have to buy a GOOD test kit that we all use here and that would be aboug $170 (and much would last ~2 yrs) Then you would use the simple ingredients that can be found at the hardware store or Walmart and never step foot in the pool store. Pool stores will cost you a small fortune and often give
bad advice along with incorrect testing.

This is the test kit you need--> TF-Pro *Salt with SmartStir-for pools with SWG
Along with about 10 jugs of Liquid Chlorine (Pool Essentials 10% at Walmart, for example) to start with. More as needed.

Once you could get good test results you would do a SLAM procedure then keep the pool chlorinated *properly* via the salt system. Using your test kit to monitor things you'll know what the pool needs, and what it does NOT.
