My AG pool has been shimmering the past 4-5 years of using the TFP method, thanks to the folks on this website :giggle: I usually open my pool the last week of May and close it the first week of September, so it's open a bit more than 3 months. However this summer I will be away for 6 weeks...

Hi, I use 12.5% liquid chlorine almost exclusively, however when I am away and have someone else take care of the pool, or sometimes when I want to increase stabilizer, I use a 1 lb. package of Bioguard Smart Shock, which contains: -dichloro 63% (available chlorine is 39%) -copper nitrate 0.7%...

Hi, As my user ID says, I am at the pool only on weekends. I usually bring the FC up close to shock level when I leave on Monday am, and by the time I get back on Thursday evening, FC is usually still above the non-SWG minimum (4 ppm). However with the very hot and sunny weather the last few...

Hi, Firstly, thanks a million for all the help the volunteers provide on this board. I have an ABP with a vinyl liner. I have 2 questions please: 1 - My TA has been only 40 since I opened the pool in early May, but the pH is stable at 7.2...sometimes closer to 7.4 after putting in chlorine...

Hi - I closed my AGP yesterday and left the pump in place for removal today...but forgot to turn the timer off yesterday :brickwall: So this morning the pump ran dry for 1.5 hrs and was still running when I unplugged. Any idea if I’ve ruined the pump? I’m thinking I can test it by pouring water...

Hi, The above ground pool closing instructions give the option to add polyquat at closing time, after Fc is at shock level for at least 24 hours. I’ve read different opinions - do I need to retest Fc after polyquat and bring it back to shock level? Thanks very much. PW

Hi all, First TFP closing here...thanks to all of you the pool water this year was perfect :D I'm closing tomorrow (I know I should wait for 60 degrees but it's not possible this year), and the FC is already at shock level (CYA= 50, shock level = 20, FC = 21.5). I'm adding polyquat60 because...

Hi all, I'm closing my AG with a Loop-Loc mesh cover within the next 2 weeks (I know <60 degrees is best, but I don't have a choice :silent: -- I always open early though). The article on above ground closing describes having FC at shock level for a couple of days, but what about the other...

Hi all, First season TFP'r here, and water is great! I close the pool myself but usually have someone open it, although now I will try to open it myself next spring. This year it was opened by someone new (to me), and he hasn't answered my calls about how his guys (turns out he wasn't present)...

Hi, First season using TFP and pool is shimmering :D thanks to you all... pH has been fine all season, but has crept up and now is somewhat higher than 7.8 When I calculate how much muriatic acid, what should my goal be (e.g., 7.4?) ? Whatever the goal, I'll add it slowly and test again so I...

Hi all, This is my first season with TFP and the pool is sparkling :D I will follow TFP instructions for closing, and would like to use (the optional) polyquat. Pool school says to follow the directions on the bottle. However, there are no instructions for closing on Bioguard All Algae 60. Maybe...

Hi all, This is my first TFP season and has been great, liquid chlorine only, haven't needed anything else, my pool is sparkling, thanks to all who help here. I told the owner of the pool company who installed my pool years ago that I want to put in a SWG at the beginning of next season. He...

I've read that it's best to have the pump running for awhile before taking a water sample, as the Fc might be lower near the surface. However I usually take a sample after sundown from a 48 inch AGP, and take the sample from elbow depth (at last 1/3 the way down). My pump goes off a couple of...

Hi, being a recent TFP follower (addict is more like it :-)), my pool looks great, but I wonder if I am over-estimating my CYA level, as I have trouble, like many others, judging the CYA endpoint. I've read many posts with hints on how to determine the endpoint. So...I've read many times that...

I'm using the K-1000 kit that comes with the TF-100 for pH. However there is a lot of room between the pH points, and I don't have enough experience to extrapolate the colors between, for instance, 7.2 and 7.5. Do many of you buy the more granular pH Box from Taylor, which jumps only 0.2...

This is driving me crazy - why would it be that I can't use the sizer with the TF-100 tubes? Isnt 10 ml the same for both tubes? thanks...

Hi, I noticed today that with pump off (Hayward Matrix 1 hp) it looks like some DE backs up into the pump basket -- I think there is a check valve just inside the DE filter (EC-40) that may need replacing...is there any downside of some DE in the pump basket when the pump is off? It disappears...

Hi - I've been using BBB for several weeks now...I leave the house Sunday and come back Friday...last week I was able to add enough chlorine before I left for the FC to be fine for my CYA when I returned today. I have a high CYA and don't want to use any dichlor/trichlor any more. Nor do I...

Hi, New BBB'r here...I'm fighting high CYA (80) but getting it down slowly... I will be away for 2 weeks, and having someone take care of the pool...I wanted to confirm a couple of things please for my understanding...I would normally use only bleach now, but these questions arise because I will...

Hi, I just started the BBB and all is going well...BUT... I live in NYC and this is a weekend house. I do NOT want to invest in a SWG now --- is there any chance I can use the BBB system if I leave on Sunday/Monday and don't return until Friday afternoon? Maybe leave the FC high before I leave...

Hello all, Many thanks for this forum. Last year I had recalcitrant pink algae (bacteria), and after reading TFP school over the winter, I guessed I had high CYA since I've used pucks from the pool place for 25 years. And I was right :( Pool was opened May 3 and pool center added 5 gallons...
