Hi, I just installed a new T9 Calimar cell. it i working fine, good voltage , amps et. However, the calibration will not count down. I did salt test ( using proper testing not strips ) and salt is at 3500. However, the Aqua Rite says 4800. Tried to do the calibration, but it is not counting...

I have solid red check salt, solid yellow check cell, and CL is stuck at 2000. Tried reset, cleaned cell etc. No joy. Just manually checked salt and it is at 3500, so must be the cell right ? Anyway, seems Hayward's are $700-850, I presume there must be good quality non OEM options for less...

So, I have been taking care of me pool for 7 years, so have a pretty good knowledge ( thanks to this forum !). Anyway, I have always tested 2 / adjusted everything two times a week, until this year - I have let it slip and not done it for 2 months. I just tested and apart from my zero CYA ( I am...

Hi, just noticed my pump is running 24 hrs. When I look at the time wheel , it seems it is not rotating and therefore not hitting the on/off switch. when I turn the pump off, I can hear it making that subtle clicking sound, but it is obviously not turning. Any one had this issue before and know...

Do you just throw it directly in the pool , or dissolve in water first ? Thx

Hi, I think I have a leak, quite probably for a very long time - however it is hard to tell. I have to fill pool about 3 inches per week during summer, less during winter, but that COULD be in normal range in South Florida apparently. However, it is a pain having to keep adding CYA every 2...

Hi, So I (unusually) neglected my pool for 4 weeks, and then found the algae. Turns out the SWG was reading the salt wrong (saying 1400) and so no FC being generated. Also, CYA was at less than 30 , so that did not help (I think I have a leak as I have to up CYA every 2 months ). Anyway, did...

Hi, The pool calcuator says CSI less than -0.6 is problematic for plaster pools and over 0.6 for all pools. I have all my levels 'just right' , however my CSI is -0.07 which is less than the -0.6 , so what can I do to get it to say -0.8 or so ? thx

Hi, I am doing a SLAM right now as I stupidly allowed my FC to drop to zero because I did not realize a leak was causing salt loss , which stopped SWG from producing CL. Anyway, it seems I caught it early , based on these tests: 23rd June 11 am (CYA is less than 30 , turns out to be zero ...

Hi, So I tested this morning and had zero FC . It was because SWG was at 2300 and not generating. It was my fault because my CYA is less than 30 and has been for a while , so I cranked up SWG to compensate as I kept meaning to do an overnight test before adding CYA (I have learned the hard way...

Hi, I have posted a couple of time about this over the last few years, and still do not really have a good understanding of what is causing it. I noticed a gradual loss of FC , even though we are away from mid summer so technically I should be lowering my % on SWG as less sun on my North...

I just bought Boric Acid , and based on the pool math I need to add 19lb to raise form the current zero to 40 ppm. is there any danger to kids / or any issues with getting it slightly wrong and say hitting 70ppm , for example ? thx Moderator comment: This post was separated out from this...

Hi, Just what can cause CYA loss of 25-30 over 6 days. Could it be the SLAM I was doing? Anything to do with the algae I was SLAMing ? Or, only other thing I can think of is that I replaced the 0013 with new one after the initial reading. Can out-of-date 0013 give a different result to the...

Hi, Been a couple of years since I tested CH. Jut tried it, and sample went VERY light pink (like when You do an FC test and get to 2 drops from clear). I then added the reagent and after 30 drops it went clear but did not turn blue. What shade of red is an indication of Calcium? I just feel...

So pretty frustrating. I maintain my pool year round , and keep it at fc 7. I test 3 times per week, add acid , baking soda , cya etc as necessary. To prep for the long days of sun, about 2 months ago I tested for CYA and it was 30ish, so, I did an overnight test (been stung before where I...

HI, Think the recent hurricane in FL flooded my pool and diluted CYA; I noticed a drop in FC over a few days, even though I increased SWG up to 85%, tested CYA and it was zero ( well clear to the top of the test), so I added CYA and raised it to 60 (then stopped as I realized I may have to do a...

Hi, Been maintaining my own pool for 3 years now, using all the methods on this site. Even over winter I test FC 3 and PH 3 times per week , and TA monthly. Just tested CYA last week for first time in 3 months and it was down to around 30...which explains why my FC dropped from 6 to 1ppm...

Hi, I live in West Palm BEach Fl, and it seems a large hurricane is coming, or at least a very big storm. Might lose my pool screen, but hopefully not. Anyway, is there anything I should do to my perfectly balanced pool, before the storm comes? Is the pool water drinkable? Always keep it at...

Hi, As I am in Florida, I pretty much maintain pool all year round. I did slack off a bit during winter (DEc and Jan) , but always maintained FC at 6ppm and PH at 7.5 . Anyway, in March I did full test and found CYA was at zero (I guess due to lots of rain over the previous 6 months) I raised...

Hi Guys, ti has been a while. Ever since taking over my own pool a year ago, things have been great, since starting over, doing two SLAMs etc. Anyway, even though it is winter, here is FL, the kids still use pool when temp over 72/73 degrees, so I have been testing CL, PH , adding acid to keep...

Hi, As I live in Florida, and have only been doing my own pool 5 months, I am not sure what pre storm prep to make. With Erkia , and of course any potential storm / hurricane around the corner here in FL, I was wondering what to do. Should I dump in bleach? Drain pool by 30% ??? Etc . Thx...

Having successfully completed 2 SLAMS in the last 3 months, the last one finishing about 4 weeks ago, I am getting warning signs I got before - i.e. SWG losing too much, very slightly over time. Two weeks ago, we were having the house painted on the outside, and as part of that, they power...

Hi, I am having the outside of my house re-painted and they company is pressure washing everything - walls, roof, POOL SCREEN , POOL DECK etc. So I am going to get lots of crp going into the pool. In the corners of my deck, I think there is black algae , so that could run in too. Should I dump...

Hi, Did a slam a while back - and it worked well - at the time I was losing 13-14 ppm so big hit. Took 3 days to clear up. Recently I am seeing a slight daily loss on FC , which had got worse and worse in the last 5 days (SWG so should just be constantly steady). I have done Overnight test...

So, as with other tests, it seems you can change the sample size and adjust the relationship between drops and counts for expected high numbers - such as CH test. Does this mean, during SLAM, you could use 5ml sample instead of 10 (get exact measure using medical syringe) and make each drop...

Hi, Recently did a successful SLAM - the scrubbing the sides, tiles with toothbrush , and digging up bits of black algae from the floor , did the trick in about 4 days. Always had perfectly clear water , and good balance, but was losing lots of FC. Since then, over the last two weeks (except...

Hi, So after 2 months and 1,000 bucks , I have my pool perfectly balanced since sacking the pool company. Today, I noticed the water was not flowing , and then saw that the pump did not come on and timer had stopped at the on time. As there was no power, I checked breaker and the fuse had...

So last night, I dropped from FC 6 to 1ppm at 10am this morning. Cannot delay the SLAM any longer. Wanted to keep a record here to make sure experts can help me do it right: 6/27/15 10am FC 1 CC 0 PH 7.2 CH 450 CYA 65/70 10.20am Added 363 oz publix brand bleach 1100 am FC 23 CC 00 11.10...

Hi, could an admin or someone change the white writing on black backround on the SLAM instruction page please? It is a really bad combination and almost impossible to read. Nice easy white background with black writing would be just great. Thx

Hi, Just joined the forum, having read all the info over the last few weeks. I appreciate you taking a look and helping out. It is a bit of a long back story, so please be patient :) I am from UK, and moved to USA 4 years ago. Originally to AZ, but last 2 years in Florida - because my little...
