Good news, the overnight test showed no loss in FC. Pretty sure my loss during the day is due to my still high CYA, after draining 2/3 and refilling, of about 65, and sun.

thank you

Hi. I have been running my pump constantly for the past 3 days. I would like to do a oclt tonight, okay to let my pump continue to run? The video on your site says to run it for 30 minutes before the Morning sample, but if it is running all night that’s okay?

saw your note about using CDX, that is what I had been using for over 4 years, and still got the slime.

Hi, I did a conversion from baquacil to chlorine this Spring. My pool was a hot mess when I opened it, as it had a pink slime issue last Fall when I closed it. If I could do it over, I would have drained it. Instead, I schlepped to the pool store and asked them to please take all my money and...

OK, FC is 9. Lets see what happens in the AM

getting a little concerned as I tested just now and FC back to 1. It was a very hot day here today, so hopefully that caused it. I used pool math to determine how much to put in to get to 9 FC and did that (about 210 ounces). I'll test now to see what it is.

Okay, new and somewhat bad test results this AM. FC = 1 CC = 0 CYA = 60/65 PH = 7.5 water temp 68 Had a good amount of rain yesterday and in the AM I put in another gallon of chlorine as I was at around FC of 3.5 Advice? Putting liquid chlorine in it now to get going and keep it from bloomin'

Did the test. This AM no loss in FC. When I went to bed it was FC level of 3.5 which was less than when I first did the test after filling and adding a gallon of the chlorine (FC was 5). BUT, it didn't go down overnight which is good. I am now going to put in the required amount to get it to...

Will do!

But is the FAS DPD test the one with the powder in the t100 kit?

Yes, we did convert that way. I can run that test but can't find the test directions at Extended Test Kit Directions – Trouble Free Pool. Clicking on the extended test link just brings me back to that page. Not sure what I am using to do that test with. I have the T-100 kit

Hi, thanks for the quick replies. I can't seem to find a way on the pool math app to figure out how much liquid chlorine to add in order to get to 7-9 ppm. Do I need to add values somewhere first? I don't have premium access and I think I already added some tests an hour ago before my...

OKAY, fill is done. Before I did anything, other than running the pump for 30 minutes, here are my test results: FC .5 CC 0 TC .5 CH 400 TA 140 CYA 60 (yeah, was 110 before) PH 7.5 I put a gallon of liquid 10% chlorine in the pool then tested chlorine 60 minutes later: FC 5 CC 0 (?) TC 5...

Okay, refill has started. While that happens should I soak my DE cartridge to clean it? If so what is recommended to use. I put a gallon of liquid chlorine in the pool while filling

Hi, at this point since I am almost done draining down to 1/3 of the water, I will post results once I get it filled back up.

Hi, draining process has been going on all day. I should have it down to having just sllightly more than 1/3 of the water left tonight. Okay to leave it like that overnight? No strong winds expected. I hope I'm doing this right, as I am measuring how much to take out by how high the water...

By drain at winterization do you mean drain it down before I cover it, and then just put the level up to where I normally have it when I close it?

To keep it sanitized if I don't drain, I assume I need to keep my FC between 3 and 5 all the time as well as my PH proper. Might not be here for 7-10 days in late August and not sure if I am going to ask my son to keep putting the liquid chlorine in. I've needed to put about 1-2 gallons per...

I have to ask, if I don’t drain the pool 2/3 and refill, will this CYA level diminish over time? My wife was ask8ng that if we just maintained the pool for the next 6-8 weeks of the pool season (whigh is when we’d cover it), then winterize and do this in the spring will the level decrease? Or...

So the day has come to start draining. I’ve been told in this forum to take 2/3 of the water out as my CYA is 110. im going to start that tomorrow am using siphon method after it drains below the skimmer. i plan on starting the refill immediately after the drain. sound okay? And once it...

Haha. Nope, haven't used calcium stuff for over a year. No idea why the level is so high. Should I test my tap/fill water before I refill? I haven't drained yet, need to time it right. I am keeping the FC level up by using liquid chlorine, may not be able to start until Monday.

Thank you

Does it make sense for me to test the tap water that I fill the pool with before I drain? What happens if the CYA level is high in that water?

Thank you!

Hi, my pool is very clear, not cloudy at all. I am still struggling to understand why it is now holding chlorine now that I'm using liquid chlorine the past 3 days. Is that because the pucks I have been using were just increasing the CYA? I obviously can't continue to just pour liquid...

Should I create a new thread with my test results?

Just FYI, these numbers reflect that I have been putting Liquid Chlorine in it for the past 2 days, and continuing.

Just updated my sig.

Here are the numbers from test #2, without CH FC = 1 CC = 1 TA = 170 CYA = 110
