Test results

FC. 6.5
Cc. 0
TA. 90
PH 7.8+ hard to see
Cya 60 - 70 ish. I wish there was a drop test for this. I can still kind of see the dot

Pool looks great. I’ll be away for a few days till Sunday so I added 2 bags of cal hypo shock and loaded the pucks into the chlorinator

What is your Calcium Hardness, CH ppm?
--edit-- just looked at your test log so 350+ppm
I would bump up your FC with liquid too.
Pull out whats left of the tabs when you return.
Have fun.

If the Cya is 70 it’s safe to swim at up to 24 FC per the slam chart, is that correct ? No eye irritation or risk of bleaching bathing suits ? Hair color change ?

 

[Oly]

Not sure why you are considering raising your FC up to the SLAM level with a clean pool and you will only be away for several days.

After dosing my pool last night for my 3 days away (I am away but family will use pool)
So it 8.1 safe to swim or do i need to take it down to below 7.8? I cold circle back and do that. If 8.1 is safe I will let it ride till Sunday
FC 15
CC 0
PH Shows 8.0 or higher on the block and 8.1 on the meter I got with my TF-Pro kit
TA 80
CH 300
CYA 80 (jumped since last night I guess bc I loaded the pucks) I wish there was a more easily discernable test

pH test is invalid when FC is above 10 ppm.

High pH may cause eye irritation. But is not overall dangerous.

What is your suggestion ? Last night I was a little lower say 7.8 block and my FC was 6.5. Based on that what the recommendation?

Thanks

 

[mknauss]

You state you added pucks. They are acidic. So let it be.

Will be doing a water exchange this weekend. my CYA is 70-80 and I don't want it to get too much higher. I am still using pucks for the rest of the season then to a SWG.

So the fill water will be colder than the pool.

What the best place to drain from and fill to?

Thanks

Great Read! Go to section 3.5, and specifically 3.5.3.

How low can you go in a vinyl pool without causing damage to the liner.

 

[mknauss]

We recommend not going below the top of the step in the shallow end. Or 12 inches of water left in the shallow.

Read Draining - Further Reading for methods to exchange water without draining.

Can this test be performed after the sun goes down ? I won’t be back until 8pm and the sun will be low if not set.

Not accurately.

Here are my results using the TF-Pro

TC 6
CC 0
TA 90
PH 7.8
Cya 80
CH 325

These numbers are after an approximate 2000 gallon dump and refill.

I am still not too confident on the CYA test in my TF100 pro kit. I glance away and look back. I can still see it - but not really. It’s kind of frustrating.

Btw- Pool looks Amazing. But I live in fear of a chlorine drop and a bloom at 80 CYA

Thanks for any input.

 

[mknauss]

2000 gallons from a 34500 gallon pool is not going to effect anything. So your CYA remaining at 80 ppm is realistic as the test is not accurate to that level (5% change in water).

Just maintain your FC level based on FC/CYA Levels. Best to keep the FC at or above 10 ppm. Let it drop to 10 ppm or just below once a week to test pH.

I ran the robot early this morning and pulled him when done 2.5-3 hours. Cleaned him up really well. I also hose off the body and power cord.

Put him away and enjoyed tbe day.

I’m just noticing that where I hosed of the robot and the power cord there is a white “mark”?on the deck where I hoses him off.

Is this chlorine residue ? Never had that before but I never ran my FC this high before.

Thanks

 

[generessler]

Almost certainly not. I'm sure the experts (I'm not one) will ask you for a full set of test results. White could be calcium. And the water you used to wash is a possible source.

We were supped to leave early today. However plans changed. I dosed the pool with 2 each 1lb bags of cal hypo shock at 3:40.

We are not leaving till after dinner. Kids want to swim.

Is this safe ?

FC was 6 before shocking the pool. Was aiming for FC of 10 before I left.

Keeping kids out of pool till I get some feedback.

Thanks
