Hello all, I have had my pool for 9yrs. Water balance has been solid and consistent for all these years On 8/24 I checked TA and noticed it was very low (20 ppm) So I added 180 oz of Baking Soda. Went to 50 ppm After that the ph and fc were erratic. The FC went to .5 one day. 128oz of 10%...

I keep my pool open around Water temp is below 60 Noticed some yellowish dust around edges and seams Brushed and ran filter for 48 hrs Had not been keeping chems balanced in Added chems Fc is 4 (SWG IS OFF) FC STAYED AT 4 ALL DAY Will do OCLT tonight, but algae is dormant in cold water, correct...

Can I use a NG heater to keep the water just above freezing for the days/weeks that sometimes freeze the pool water? Our area usually does not get below freezing for more than a few days. But last year we had 2 weeks of Temps in the teens that froze the water.

Anyone have experience piping in a gas heater along with a heat pump heater? I keep my pool open year round. Up til this winter, I never had any water freeze, but this year I got 4" of ice during 8 days of sub zero temps. I am wanting to add the gas heater in order to just keep the water above...

I have noticed that my Multi port seems to be leaking into the section of 1.5" waste line. Because I keep that waste line valve closed off about 2 feet from the multiport, I can tell it fills with water over a period od several weeks. I also noticed that the water in the sight glass is...

I just installed a Pentair Intelliflo pump. I am confused about determining the flow rate at a certain RPM The Pentair Pump Performance Chart seems to say that at 2,350 RPM (one of the pre-sets) it does about 90 gpm which in my 26K pool would mean about 5 hrs run time to get 1 turnover I was...

Can I assume that if I have had and defeated the yellow Mstrd Algae, that I should now keep my FC at the appropriate Yel/Mstrd Min (7.5) from now on? Not sure which column on the chart is appropriate for my situation Also at what FC level does the PH test become invalid, FC 13 (coming down...

My phosphates are apparently quite high. (2500) I have no way to test with my tft 100 kit so I took water to the pool store :( Do I need to lower the phosphate levels and if so what is best way to approach this? FYI, our city water comes with 200ppm phosphates More details below if you are...

Hi all, here the details of my latest algae fight: Have been keeping pool balanced all year FC between 3.5-4.5 Ph stable at 7.5 TA stable at 50 CYA had dropped to 30 ish due to lots of rain, evaporation and consequent replenishing with city water Last week was very hot ie upper 90 s all week I...

OK, this is strange. Last fall, in November, my CYA was at 40 ish The only chems added through the winter is bleach to keep FC at around 3 ppm I did not check again til a week ago. I had assumed it would be very much lower than 40 because throughout the winter I have replaced 16 to 20 inches...

Wondering what is making my FC rise Has been very stable all summer. The last week or so it has been creeping up about a 1/4 to 1/2 ppm per day A few days ago I started to lower run time. No change so I lowered % from 45 to 35, no help Any ideas? Current levels: FC-6, PH 7.6, TA-70, CYA...

My white sufaces, mostly steps, started to yellow. I tried a product called StainFree (Ascorbic Acid (vitamin C on steroids I think) Am worried that the StainFRee is using up chlorine. Directions were worthless. Said to lower chlorine to 1ppm before adding, wait 24 hrs then vac and BW. Then...

I thought I would post some info on the Zeolite mineral used in lieu of sand Zeolite is a mineral, but there are various mines that is is mined from and several different types/qualities of the mineral What can be confusing is that there are at least 3 companies that sell Zeolite Mineral but...

I am in Virginia Beach and am not "closing" Can I let salt levels and cya be a little low for the winter? Had to empty 10-14" during the Sandy Storm and my CYA is now 35, salt around 2600 FC, PH, TA all withing range and seem pretty stable 5.5, 7.6, 60 respectively Thanks, Cush Dobbs

I am in the midst of an algae shock I have 0 cc I have sparkling clear water I continue to have an average of 4 ppm OCLT results So I began to wonder about the 1 ppm or less requirement 1 PPM is 20% of and FC of 5 20% 0f 30 PPM (my Algae shock level) is 6 PPM So would not 4 PPM be OK? Just a...

How do I post a photo of my pool

I keep vacilating on what to do about a yellow "film/dust" that accumulates on seams and creases, mostly on the opposite side of the returns. I was going to do yellow algae shock ie 40ppm shock But the overnight FC Loss test showed under 1 as FC loss, CC was at .5 or lower, and water was clear...

Could someone clarify the shocking process. I have never done this, but think I may have some yellow algae? Sorry for the lengthy post but I want to be sure I do this right: I have a yellow substance that collects along the creases where the side walls and or the slopes meet the bottom. The...

I found a contradiction in school rules and just wanted to make sure I am doing the right thing with the water balance The Pool School section on the relationship between Cl and CYA (chart and all) says to drain pool water if CYA gets too high...above 80. The Water balance for SWG section says...

What is the best way to post a question, say on warm weather and dull water? I probabably can't see the trees for the forrest, but I can'tfigure out where to post a new question. I will appreciate any guidence Cush Dobbs

Hi all, I am haveing a hard time with my new pool. The water is clear, chems are good. But I keep getting a fine dust/sandlike debris that settles in the same spots after every vacuuming. I will try to report clearly on what I have done to date to find out what is happening. First I was...

I have been trying to find where I can post a question about how to add salt to an SWG pool as I am low on salt. 1- Is there a preferred method of adding salt? (I looked all over the site for the topic. 2- I could not find where I can post the new topic, so I came to this place on the site...

Since I am still a bit green to pools, what is the proper way to run my filter during the swimming season? I left my pool open this winter and have been doing great keeping the water clear and balanced. Wondering what sort of changes I will encounter when the grankids start enjoying it...

Hi, I have a pool vacuum question: I am new to pools. Have had my new pool for a few months, been using an auto cleaner. Decided I better make sure I know how to use the manual vacuum so I tried it today. My pool is 25K, vinyl, with 2 skimmers, 3 returns plus two more at the steps. Two speed...

My pool water is about 45 degrees. (I let the test water warm before testing, is that the right thing to do?) My automation panel will turn on the pump at low speed when air temp is below 38 or something, but the pool company that installed the pool set up the pump to run 22hrs every day at low...
