Newbie - White Mold + So many questions

Jump to latest Follow Reply
Ok I just did my first test with the Taylor kit. That was.. stressful? Here are my results that I don't really trust:
I did the chlorine test three times and in the end I "think":
FC- 1
CC- 0.5
ph- 7.6
TA- 100
Calcium hardness- 260
CYA- the dot never really disappeared. I could see it even filled to the top (pic attached)

No idea what to do from here. I suppose I need to add liquid chlorine?
I don't feel confident in these results. Should I take a sample to the pool store and see how that compares?

That’s OK You can do the FC test again. DON’T GO to the POOL STORE.

Did it turn pinkish when you add the powder to the 10ml sample? Then you added 2 drops and it turned colorless? That would be a FC of 1ppm. Then you add 5 drops of R-003 and if it turned pinkish again, you added 1 drop and it went back to colorless? THat would be the 0.5ppm of CC. If you wait too long between adding drops the sample can go back to pink so you need to be timely in doing the CC test directly after the FC test.

You CYA is definitely low but that is a test you can do again as well but the picture does show you can barely see the dot.

Your FC may be low because of no or very low CYA. You need to add stabilizer. Check with pool math on amount to add. Suggest you add the granular by sock method. Only add half of what PM says because you do not want to overshoot. Also, it could take 48 hrs for stabilizer to mix throughly so don’t expect an immediate increase in CYA. Test in 48 hours and then may need to add more stabilizer Run your pump to mix.

Now also add LC to bring up your FC to at least 5ppm. Then set your IC SWCG to maintain that level.
 
Herman gave you a great plan.
Assume the CYA is 30 ppm. Add 10 ppm more CYA stabilizer product using the sock method. Re-test in a couple days after that is dissolved. Do add LC now.
When you do the CYA test, try this next time.

Once you have your solution ready, back to the sun, etc. Fill the vial to a line, say 80, lower the vial to your waist level and glance for the dot, you see it, add solution to the 70 line, glance, see it, repeat until you no longer see it with a glance. Then use the CYA value one step above the line you read. So if you stopped at 50, use 60 ppm CYA.

The vial is in logarithmic scale. So it is not viable to interpolate between the lines. Just use the whole numbers, such as 50, 40, 30, ....
 
So I just went to the pool store and the results are similar. My concern is last week after I shocked before I got the kit, my FC was 6 and I put the chlorinator at 75%. Does this mean my chlorinator isn't working? Also there is still a large disparity between what salt level the pool company is reading vs my app. My app says 3950, theirs says 2750. That's a huge difference. What do I do now? Add chlorine? Or run super chlorinate and see what it does? How do I know if my chlorinator is working?

Sorry I panicked and went before you guys responded. I'll go buy some lc now. I think I still have enough stabilizer to bring it up so I'll add that too. I'm just worried that the salt cell isn't working
 
Ok I put it into pool math and this is what I got. Sounds correct?

Great.
Once the CYA stabilizer is fully dissolved, test again after 24-48 hours.

Add the LC as soon as you can.

Are you still having white mold, etc?

No more mold. Water is clear. Just worried about that salt disparity. I hope I didn't get a defective cell
 
I would not trust a pool store test result.

If your Intellichlor is happy with your current salt level, all is good.
 
Ok I'm going to add it all now. When should I test next do you think?
I forgot to mention that the builder fixed the weir which was a big issue too

One more edit: I had my swg at 75% since last week. Should I leave it there?

The IC SWCG has lights on top of it that tell you if it is chlorinating, if salt level good, etc. If that unit is happy then it should be working.
 
Great. You are generating 4.8 ppm FC per day into your pool volume. That should be sufficient once the CYA is up a bit more and there are no organics destroying the chlorine.

At 75%? Ok I'll keep it there then. I'll update here with tomorrow's FC?
