meanwhile in Florida

[gussie1966]

I've had some either iron/brown algea trails. Less each day. Filter brownish. Water is perfectly clear. Brushing/vacuuming daily. Changing filter every other day. Pump running 24/7.
I use 10% chlorine bleach. Newbie using only TFP method

FC 10
CC 2
TC 12
pH 8.2
CYA 60

Any info on where to go from here

 

[mknauss]

With a CC of 2 it is implying you need to SLAM.

Good luck.

Agreed. Any time the CC get to be more than 1 drop to clear, points to something going on in the water.

Have you added any "odd" chemicals to your pool recently?

Lower that pH and then follow the SLAM Process process.

Newbie only using TFP. Liquid chlorine. So with a CYA of 60, I need to FC at 24 which for my pool size/current FC would be 2 gallons and a cup. And 84oz borax to get pH down

Does that sound correct? still learning pool math. thanks

What strength bleach? To go from FC 10 to 24, using 10%, you need 269 oz. Or 2 gallons and 2 cups.

Be sure to lower your pH to 7.2 first and confirm with a pH test after 30 minutes of circulation.

Plan to test and dose with liquid chlorine every few hours at the start.

Take care.

borax raises pH. You need muriatic acid to lower pH.

 

[gussie1966]

ok so went to get muriatic acid this morning. My local hardware store does pool test so being curious I took a sample.

Their test read

FC 2.1
TC 0.9
CC -1.3
pH 7.7
CYA 25

wow! my reading this morning

FC 10
TC 10
CC 0
pH 7.8-8 hard to read the colors for me
CYA 55

should I do anything to pool?

 

[gussie1966]

ok home from work and rechecking water. Water is crystal clear except for small iron/aglae trails

FC 6.5
CC 0.5
TC 7
pH 7.7-7.8 I think, hard to read the colors for me
CYA 55

any help

 

[mknauss]

Are you SLAM'ing? You said yesterday you were. If so - follow [FC/CYA][/FC/CYA]. Lower your pH first.

 

[gussie1966]

I picked up muriatic acid this morning. Just added after getting home. Waiting to check pH

 

[gussie1966]

got pH down then added chlorine last night to bring up to 24 to slam

this morning chlorine was down to 18

brought back up to 24. brush/vacuum

CC was .5

 

[mknauss]

You can save your reagents and not test CC. Only do that when you do your OCLT.

Take care.

 

[gussie1966]

ok so home again. FC down to 17 added another gallon of chlorine per pool math. I'll check again before nightfall.



Should I be losing chlorine that fast? anyone?

 

[mknauss]

Yes. you can lose chlorine that fast. That is why it is best to test and dose with chlorine every 2-3 hours at the start of the SLAM. Having longer periods lets the algae grow when you are below shock level.
