Normal FC loss during day

[TCJ4]

Just checked the chem level.

FC:0.8 using the 25 ml test and 1 using the 10ml
CC:0
Ta:90
Ph:7.7 added 5oz of dry acid

After how long can i test CH and CYA after adding dry accid?

 

[Bama Rambler]

Immediately, but I'd probably wait 30 minutes for the pool to circulate.

 

[TCJ4]

Can the dry accid effect the CH and CYA test?

 

[Bama Rambler]

No, unless you poured it directly into the sample vial. And then I'm not sure it would.

 

[TCJ4]

After i test CH i will add some cal-hypo to raise my FC to 5 and at night raise it to slam level.

Yesterday in the evening i used the 25ml test and got the same 0.8 as today.
So it did not dropped

 

[TCJ4]

Ok i'll go ahead and test them now

 

[TCJ4]

CYA (45-40)
CH:70
PH: 7.4

How's your Calcium?. CalHypo adds a bunch of calcium. I can't see what type of pool you have.

 

[TCJ4]

It's in my signature.

Intex 15x48"
CH 70 (just added 5oz of cal hypo)

I can't see signatures or photos when using Tapatalk on my iPad.

I just asked since you were using Hypo and most here use liquid chlorine.

 

[TCJ4]

Oww ok

 

[TCJ4]

I added 5oz of cal hypo which should have raised my FC to 5 but it only raised it to 2.6.i now added another 3 oz to raise another 2.5

Just wondering if i did something wrong using the pool calculator or is the chlorine being consumed that fast.
I added the 5oz and after (20-30) i tested the FC.


I use the pool calculator app

 

[Bama Rambler]

What strength Cal-Hypo do you have?
Did you choose the correct strength in the Pool Calc?

 

[TCJ4]

68%

In the swim brand

 

[TCJ4]

Ok just checked the FC again it's 3.5 and CC is 0
I have added a 3" trichlor tablet to help me keep the FC higher. I put it in the skimmer basket when the pump is running and when it's off i put it in the floater

Do u guys think i should still raise my FC to slam level and do the OCLT?

 

[linen]

Yes, I would do the OCLT, but get your FC up to close to your SLAM level (16 ppm FC for 45 ppm cya per poolcalculator.com) before doing it.

I have added a 3" trichlor tablet to help me keep the FC higher.

We don't recommend putting anything in the skimmer since that can cause high levels in the skimmer, pipes and equipment. In addition, keep in mind that each puck will add about 6 ppm cya to your pool.

 

[TCJ4]

Will it be a problem if the pump is running?

 

[techguy]

Moving from CalHypo to trichlor is not the best choice. Using liquid chlorine will SLAM your pool faster and you don't need to worry about CYA additions or damage to your skimmer basket or pipes. You can simply turn on the pump and pour it slowly in front of the water as it returns to the pool.

To go from 3.5FC to 16 FC in a 5000 gallon pool that's about one 121 oz jug of Chlorox/Great Value Extra Strength bleach, $3.00 at Wal-Mart.

 

[TCJ4]

Ok i'll go check some bleach later.

BTW: here in aruba we don't have walmart,and i saw at supermarket a 1gallon jug of i think 6% bleach at 7 florins($4)
(Our currency is in florins)

Ouch, I can see why you use other forms.
