Hi Mendy, I will try to take a pic when I am back home tonight. Yes, I can see the bottom well. Very slight cloudiness. THe pollen season is over several weeks ago, so I assume there is no pollen. The cartridge filter pressure has been quite stable at 15psi. That's why I am puzzled. I am also...

Will go to buy some liquid chlorine today. A fun project for the weekend.

Thanks Mendy. I did OCLT last night, no FC loss. In addition, my SWG is off at night. Do you still think I should do a SLAM?

By the way, I have sta-rite system 3 cartridge filter

Thanks both. Sorry for the delay since I was out of town. Yes, I did OCLT, and no FC loss. The pool is not crystal clear although I see the deep end well. Haven’t got chance to add CYA yet. Ordered 2 gallon of liquid conditioner from amazon. Should arrive tomorrow. Still puzzled about the...

A quick question about water chemistry. My pool water is slightly cloudy (I mean slightly). I may just live with it. But like to hear advice from TFP. Here is my chemistry: Free chlorine: 6ppm Combined: 0 PH: 7.5 (added MA yesterday. I am adjusting pH every week, SWG brings pH up rapidly)...

Hmm, mine is at 100. That might be the reason for pH instability

Thanks Jim. Yes my TA is around 100. Didn’t think about this before.

I seem to have a little trouble maintaining pool pH. All numbers are reasonable except pH. It was 7.8 three days ago so I added about 30 oz MA. It is around 7.8 again today. I know it is sometimes hard to manage pH with SWG. Is that normal to add MA so frequently? Am I missing something else...

Opened the pool two weeks ago and CYA was slightly below 30. So I bought one gallon of liquid stabilizer which should increase CYA by 12 ppm based on the calculation. Added 7am in the morning, 7 hours later CYA still reads at 30. Am I doing something wrong? Searched forum, people seem to be...

Thanks Richard. Will do it.

CH is at 140. I assume it is fine with vinyl pool. My concern is around high pH, and TA.

haha, stuck at work now. Will work on chemistry over the weekend.

I am not quite sure if this is the Algae. My FC has been stable at 3-4. Overnight chlorine loss shows nothing. CC is 0. Is that still possible with Algae?

Do yo think I need to adjust CYA level as well? Thanks.

Just read pool school article regarding TA for SWG pool. The recommended range is 60-80, but I am at 150. How can I lower the TA? Does this link to my high pH?

Yes, I brush the deep end every couple of days. I do have concern of pH and TA.

it has been a month since I opened the pool. The pool is clear. But look at the deep end, it is not perfect clear as before. Always feel it is very slightly cloudy. I checked the chemistry regular using K2006. FC 3.5 CC 0 Ph 7.8-8.0 TA 150 CYA 40 Salt level somewhere 3800-4000 Filter...

So is 4000 ppm the safe level for vinyl pool and pool equipments? Thanks.

My bad. Totally forgot to check the SWG manual. I guess 4000 ppm won't corrode the equipment or pipes if the manual says 4500ppm.

The PB added 4 bags of salt when opening the pool, and the salt reading was 4000 ppm. Was told it was perfectly fine. Is that correct? Checked some articles, each gives different ranges. Thanks.

I do have salt water pool. haha, this might be the most expensive sodium chloride solution :)

Thanks. What I am worried is the degraded by product will hurt the pool or vinyl. If not, even 6% is not bad.

Just found out two gallons Leslie liquid chlorine in the shed from last summer. Can I still use them or have to get rid of them? I know the strength will be weaker. I am just afraid it will create some damage to the pool by using old liquid chlorine. Thanks.

Hi Dom, A quick update. Did the SLAM over last weekend to early this week. Water is clear for several days. FC level is stable. Looks all good. The only thing so far is the filter pressure. I have Sta Rite system 3 cartridge filter. I cleaned 5 days ago when pressure was 19psi. After cleaning...

FC 1.5 TA 160 Calcium hardness 260 CYA 65 ph 7.6 taylor k2006 kit I will start SlAm today after getting some liquid chlorine - - - Updated - - - By the way, the water is a little cloudy this morning.

just a follow up. Have been extremely busy for the past three days. Didn't get a chance to SLAM the pool. But what I found is the filter pressure goes up 1 psi per day. It is somewhere between 19 and 20 now. Is that something I should worry. My short experience with pool filter is they were...

;Thanks so much. So I will star SLAM this week. Do I have to use algaecide at the same time?

Filter pressure is still climbing at slow rate. Now it sits at 17.3. this is sta rite system 3 S7M120 filter. I was told it only needs to be cleaned once a season. In Massachusetts, this is about 3 months. Never thought it went up so quickly. It has been stable at around 14/15 since pool...

Since I need to go to work today. I just use super shock it 73. Predissolved and slowly pour in front of return jet. I want to do SLAM this afternoon after back from work.
