Help with algea

[MITBeta]

You should get your pH into the low 7s now, but 7.2 is suggested.

Then you will use less chlorine overall if you increase CYA to 30-40. If you're confident in your 20ppm read, add another 10ppm and boost your FC level to 12ppm for the SLAM Process.

 

[jeffchap]

Forget about pH for now. Your CYA is a little low, but acceptable. The only thing you need to worry about until the water is clear is FC. Follow the SLAM protocol and keep it at 8 as often as you can.

Once the water is clear, we'll have you do an overnight chlorine loss test (OCLT) and a CC test to see if your SLAM is truly complete. But until the water is clear, nothing matters but FC.

While I am getting pool to 8 ppm fc do I need to keep pool running?

SLAM Process

• Run the pump 24/7 until you are done SLAMing

I was told I don’t have a main drain so what is the drain looking thing in deep end?

 

[PoolStored]

Hey! Can you take a picture of your equipment and a picture of the drain looking thing in the deepend? This will help us figure it out...

Here is my equipment, but still cant see the bottom of pool to take a picture.

How many skimmers do you have?

my numbers today are fc 1, cc 1, TA 140, CYA lower then 20, and PH 7.2. What should I do next?

 

[Kivare]

I'm getting more shock today

 

[PoolStored]

Do you have returns on the side of your pool?

What to do:
1) If you don't have pool math, download it. PoolMath
2) By "Shock" I hope you mean Liquid Chlorine? Yes, I would get a bunch of Liquid Chlorine, you will need it. I went through 35 gallons for my 30K gallon pool when I SLAMMED.
3) Use pool math to determine how much CYA (labeled as "conditioner" or "stabilizer" Buy at least that much. Make sure it is 100% Cyanuric Acid.
4) Read the following and follow the instructions:

SLAM - Shock Level and Maintain

How frequently are you testing FC and adding bleach/chlorine? You need to be doing it 3-4 times per day at a minimum, and more if possible. If I was home, I'd check it every hour if I were you.

Any time your FC drops that low, algae just begins multiplying again. So it's two steps forward and one step back. The more you keep FC at SLAM level, the faster it will clear up.

I was testing at least a couple times a day. Yesterday it was at 7 but today its low again. I have been putting in shock not liquid chlorine. I put stabilizer in a few days ago, but didn't seem to do anything. I do have baking soda is that ok to raise CYA?

 

[jeffchap]

Be careful not to raise your CYA (aka stabilizer) above 30 ppm. It can take a few days after adding to show up on the test.

At this point, I would use strictly liquid chlorine (aka bleach). Your pool is really green. It didn't get that way overnight and it's not going to get clear overnight either. The one thing you need now most in addition to bleach is POP - pool owner patience.

It *will* clear up with enough chlorine. We've seen worse. But it could take a couple of weeks and 50 gals of bleach or more. At this point you need to decide if it would be more economical to drain and refill. But should you decide not to drain and you stick with the SLAM religiously, I guarantee you it will get clear. We are here to help whichever way you choose.

all you did was add liquid chlorine?

 

[jeffchap]

all you did was add liquid chlorine?

Chlorine and a gallon of muriatic acid to lower my pH. I used maybe 12-15 gallons of bleach. It took more this year than most because I didn't realize that my saltwater generator was dying. Most years, 6 gallons or so gets me up and running again.

 

[V___25]

Late on the party here but that's a big pool and sand filters are the slowest at clearing. It's definitely going to take time. Along with all that chlorine, you're going to need extra pool owner patience. The green will fade into milky blue cloudy eventually and that's where it feels like it will hang forever but trust the process. It will get you there. And you'll never give the pool store a dime.

I have put so much bleach, liquid chlorine and shock and its still green, not as bad but still not clear. So should I take the shock back and just buy liquid chlorine? My PH is good, so don't need acid. My chlorine gets high then it goes away over night.

 

[jeffchap]

You can keep the shock - there are times it can be handy, like if you need to raise your CYA. But for now, only add liquid chlorine and keep your FC at SLAM levels as often as possible.

When is the last time you tested your CYA? If you've used shock since then, it would be helpful to get a current reading. Then make your FC target 40% of whatever your CYA is.

The trouble with powdered shock (dichlor) and pucks (trichlor) is that it also raises your CYA level which reduces the active chlorine levels which means you need to raise the chlorine level even more to be effective. Liquid chlorine is just chlorine and saltwater so it doesn’t add extra stuff.
