algae bloom

We are first time pool owners and are struggling to completely clear our pool. I’m working on going through Pool School but I wanted to see if anyone could help with our current situation. Is this dead algae or living algae? We had a pool service come out yesterday and within hours there were...

Alright, I was hoping not to have to make this post… as I have tried to follow all of the recommendations closely, but here’s the story. I built a deck around my pool this spring and during the process the pump was unplugged to be moved and hard piped (for about 3.5 weeks). During that span I...

I have struggled all summer with this stupid pool. I have learned more about pool chemistry than I would ever want to know. I just cannot keep the algae at bay. I had a beautiful period after a slam for about a week then that’s it. Now I just want to close it but cannot clear it up to close it...

So I am trying to close my Coleman 22ft above ground pool, but was on vacation for 3 days came back to an alagae bloom. have used 2 bags of hypo cal shock for 13,500 gallon pool and also have used 4 jugs of liquid chlorine. We have a robot vac that doesn't do very well and the dark green alagae...

I have a spot on my pool that has extremely stubborn algae. I've tried brushing it off with a brush using metal bristles. A solid 50 back/forth strokes didn't do that much sadly. In the past, I was able to brush the algea and it would basically 'dust' off into the pool and would be easy to...

13,000 gallon pool SWG and using Hayward EC40 filter. Can’t get the algae under control. Chlorine is currently about 3-4 ppm and CYA is about 55. I know this is a bit high for CYA but initially I tried to SLAM it at 30 ppm but I couldn’t keep chlorine over night, and the sunlight has been...

It's been very hot here and a day a go I saw it, the dreaded algae on my steps. My chlorine was in range so I was surprised then I remembered that my pump was still cutting off 9pm to sunrise (sometimes I'm not that smart, I do that when it's cooler...hello it's summer). Anyway, got in it...

Hello all! I opened the pool back on Memorial Day weekend, and while there's been slight light at the end of the tunnel, Im at a loss. Last year, the pool was sparkling, and a thunderstorm wiped it out in minutes. I watched water runoff from the yard, and tree debris go into the pool and it...

We can clear the pool up and keep it that way for about a week making sure the chlorine stays at the right level and all but then it will go green. Any advice?
