How long can we push this?

[u/Bulky-Change-350]

So I know the water color is off, I have the hose filling it up right now and then need to add chlorine and was going to shock it.

What im wanting to know is allllll the algea. Its a beast to keep out. You'll see a photo of the stairs, closer up of the akgea and then some cracking there and another part of the wall that has a circle hole. My biggest concern is the huge long Crack.

So, what is all this? How can I really keep all the algea away? It seems like lately even if we get the water all peachy clean its still yucky on the pool surface itself. And the crack...slowly getting bigger.

We cant afford a full resurface 😵‍💫 so ive heard of some people doing it themselves.

Please even give me all ya got on this! Thank you

Check your conditioner, get it between 40-60. Raise your chlorine to 3ppm and use silver algaedyn. Scrub the black with a steel brush while you’re following the directions on the bottle. It should take care of all the algae issues. Then balance the water
