Jim, I am just doing what is recommended when I use “Pool Math”. It says “To lower TA you reduce pH to 7.0-7.2 with acid and then aerate to increase pH.” My TA is always high (as high as 140 once back in July). When I was tracking it close, I got it down to 70 using the Pool Math logic. I...

I started a thread: “Rookie Pool Owner needs some advice” on 20 July and kept going with it until 21 Aug. I kept doing what I thought I should do and I think things are going pretty well. I had a black algae problem that took about 3 tough weeks to clear up, no more a problem thanks to y’all...

My current stats: Cl: >5 pH: 7.5 FC: 8.0 CC: 0.0 CH: 450 TA: 90 CYA: 45 My FC was 7.5 Monday and got as high as 9.5 on Wednesday. I guess the SWG is keeping up, but we haven’t had much sun all week. I still can’t say for sure that my SWG will be able to keep up or is producing. It's still...

My stats as of 1900 yesterday: Cl: >5 pH: 7.6 FC: 7.5 CC: 0.0 Added 64 oz 31.45 MA Mostly cloudy all day. My stats as of 1700 today: Cl: >5 pH: 7.3 FC: 7.5 CC: 0.0 I didn’t test CH, TA, and CYA either day. We got 1.1” rain, mostly overcast all day. FC dropped from 10.5 on Saturday to 7.5...

He didn't say he would replace it, but I sure would hope so or else he will get a very bad review on eBay. He also said that it would give an error code if there was something wrong. I guess that's why he wanted me to continue with it. Thanks!

I talked to the person I got the new PureLink1400 cell from. I told him that I didn’t think the cell was producing chlorine and explained what I had done. I mentioned that last night the FC was 7.0 and he said that was very high. He initially said the recommended level was 1.0 to 3.0. I said...

I just did an OCLT two days ago. Do I need to do another?

I set the SWG to 100%, but no change. I have never noticed the bubbles from the return, unless there was air in the system like when it first comes on. I did an OCGT (overnight chlorine gain test) last night. Tested FC at 2100 – 7.5, turned pump on and set SWG to 100%. Tested this morning...

I set my SWG to 90% and it runs 3 hours in the morning and 5 hours in the evening. I tested at 1500 today and FC was only 7.5. I checked directly in front of a return jet and it also tested 7.5. The main reason I started this thread was concerns about my SWG. I replaced the cell and there are...

OCLT results: 9 Aug, 2030: FC-14.5, CC-0.0, set SWG to 0%, left pump on 10 Aug, 0500: FC-14.0, CC-0.0, SUCCESS! I left the pump on all day and SWG at 0%. 10 Aug, 1510: FC-10.5, CC-0.0, mostly sunny all day, 78oF this morning, 99oF now Should I set the SWG to produce? If so, how much? I...

The CYA was 75 on 30 July. I don't know how accurate that is. I mentioned my concerns about the CYA test in my post on 23 July. I'll do a OCLT and post the results tomorrow. Thanks!

An update on my pool status: 6 Aug, pm: FC-13.5, CC-0.0, added 2.5 gallons 10% liquid chlorine, scrubbed entire pool 7 Aug, 0730: FC-23.0, CC-0.0 7 Aug, 1500: FC-18.0, CC-0.0, added 3 quarts 10% liquid chlorine, scrubbed entire pool 7 Aug, 2000: FC-18.0, CC-0.0, added 3 quarts 10% liquid...

The pH is 7.8. I can dump 1/2 gallon of 31.45% MA to bring it down to 7.2ish, since my TA has been high. And put the SWG back up to 90% and dump in some more bleach. How long should I keep it up? Thanks!

Thanks, that's what I figgerd. Should I do all the tests while the FC is below 10? I've only been checking FC and CC since last Saturday.

Thanks for the reply, pooldv! Sorry I didn’t take the time to get back sooner. I must have miscounted the test on Tuesday when I said the FC was 29. It was 14 the night before and I added 2 gallons of 10% liquid chlorine. That would only bring it up to around 19, which makes more sense. I...

Forgot the test updates: 0510 this morning: FC: 29.0, CC: 0.0 1500 this afternoon: FC: 14, CC: 0.5 My son mowed around the pool today, but there wasn’t much grass in the skimmer baskets, one had two frogs. There were a lot of bugs in the pump basket, so many that it was restricting the flow a...

Thanks for the reply, max2k! I tried to take pictures of the problem area, but the spots don’t really show much anymore. I’ve been doing a lot of scrubbing the past few days. I set my SWG to zero before I did the OCLT that I posted about on 31 July. I’m not sure when the next time I can...

Thanks for your reply, pookiv! I’m a rookie at this. I don’t think I have algae. The water is clear. I can easily see the drains. The reason I thought it may be black algae: Some areas of the plaster are pitted and there are many other imperfections in it that have very dark shtuff in them...

No replies. Maybe I need to start a new thread. I’ll try one more. I did not start a SLAM yesterday. I think I may have a black algae problem so I’m trying to follow the directions for that. After scrubbing most of the pool yesterday evening, until it was too dark to tell if I was doing...

I guess a SLAM may be in order. I did an OCLT and FC dropped from 7.0 last night to 6.0 this morning (CC-0 both). Will the SLAM also solve the other problems I indicated? Thanks

I don’t know if this thread is still active since there were no replies but I’ll try it and see if anyone has any comments.. My PureLink1400 cell came in today. The numbers a few hours ago before replacing the cell: Cl: >5 pH: 7.4 FC: 7.0 CC: 0.0 CH: 550 TA: 90 CYA: 75 I replaced the cell and...

I started a thread, Rookie Pool Owner needs some advice, in Just Getting Started, but I thought I could start a thread here since this deals with equipment. My 7 year old PureLink1400 cell does not appear to be producing chlorine anymore. It was working up until about a week ago. I’ve had to...

I added 3 gallons of Pool Essentials Chlorinating Liquid (10%) and brushed the whole pool. These are the numbers after that: Cl: >5 pH: 8.0 FC: 8.0 CC: <0.5 CH: 425 (thanks to 3” of rain) TA: 110 CYA: 65 I added another half gallon of the liquid and tested about two hours later and the FC was at...

Sorry for this long post. I hope someone can offer some advice. My TF-100 test kit came in today. Here are most of the results: Cl: 0 pH: 7.9 FC: 0 CC: 1.5 CH: 525 TA: 140 CYA: not tested The sample of the Chlorine Drop Test turned slightly cloudy with the R-870 powder but did not turn pink...

Thank you both for your quick response! I just noticed the link to TFTestkits.net while I was waiting for a response. Do you recommend any test kit "options" to get the total above $100 to get free shipping? I already have all the nets, rakes, and brushes I'll need for a while. Thanks!

I found your website and looked through some of the posts and started using PoolMath which seem to be very helpful. I purchased a home with a rather large pool in December and am having some problems getting the chemistry right. The water generally looks, feels, and smells fine most of the...
