I can not thread it into the hole without the light in place, the screw slides through. That said, I don’t understand how it could have so quickly stripped out as it was being held fine before I unscrewed it today. So it does seem as though the problem is with the threaded female hole in the...

Thanks for the reply. The light is seated properly, with the cable neatly tucked in. I did see that article, however, I’m curious how a longer screw will hold the light in place since the screw is passing through the tab in the niche housing without catching the threads, so it seems to me that a...

Hi. Our pool light stopped working so I removed it to ensure everything is fine, which it is, so jt must be a bad LED bulb. When I go to screw the light back in, the screw won’t catch to the niche housing (the threads appear to be fine) and the screw just slides in and out as if the housing is...

OK, thanks. I’m hoping I don’t need to use the 50 lbs of trichlor before bleach becomes readily available again. But unfortunately, there’s a financial aspect of this too! It’s possible my CYA is lower than that number as I have never been good at reading the test (a lot of subjectivity with...

Hi. Yes, CYA is currently low (~60). Here’s the thing, I’ve got a 50 lb bucket of tri-chlor so until I can get back to bleach, I’d prefer to use that.

Hi all. Hope everyone is safe out there. Due to the current shortage with bleach availability, I’ve had to resort to trichlor pucks (for now). Our PB installed a chlorine feeder but it seems to not be sending enough chlorine. I have it set to the maximum and yesterday I cleared out a small piece...

sorry, not sure I understand the response. do you mean to see if this product from Ocean State Job Lot will do the trick? if so, just to play devil's advocate, isn't tri-chlor essentially the same thing as well, but because it adds CYA due to the manufacturing process, it's not as recommended...

Hi. Thanks for the reply. I buy my bleach from our local grocery store, Market Basket, which is a very reasonably priced store. It is typically $3. for a 121 oz bottle (8.25%), but I have seen it higher. As previously mentioned, I lose any where from 2-4 ppm/day. I'm not familiar with the...

A few posts back, someone asked if I lower my water in the winter. Yes, In upper New England, we lower our water level below the skimmer/returns and during the winter (when we're not in artic temperatures), I peel the cover back and bring the water back to that level via a siphon as rain and...

Thanks for pointing that out, that is exactly what I’m saying. And just updated my profile again for geography. The problem is that I did not out have my birthday info in there so it didn’t save the first time. Not sure why bday info is required to save geographic location (or at all, for that...

Hi. Here’s where I struggle. I have been on the BBB method for a couple years and have done my best to fully embrace it. Before that, I was using trichlor pucks and did not test every day (or even intra day) and had very few water problems. If 2-4 ppm is consuming approx 60 oz of bleach per day...

Hi. Thanks for the reply. If I’m losing 1/3 ppm daily, isn’t that high? If my target is 6 and I’m at 4 or less each morning, isn’t that more than 10%, or am I misunderstanding? I’m located in Rowley, MA

Hi. Thanks for checking in (had out of town guests for the past several days so haven’t been able to respond). There has been some stabilization, FC typically test out at about 4 ppm every morning (occasionally lower depending on usage and weather), and my CYA test is between 40-50 (have not had...

At this point, the whole bottle 1.75 lbs. which ended up being around 35 oz by volume. CYA this morning is closer to 30 (give of take, of course).

Thanks. As I said, I must’ve missed that somewhere but it’s not a note on PoolMath or referenced in the CYA chart page, so perhaps links from there so that others don’t miss this helpful info? I am doing the sock method now and will test in 24 hrs.

Hello all. duraleigh, i don't mind you shouting, as I'm sure there are a lot of people who have not read Pool School and don't use Pool Math correctly, however, i'm not sure why you think I have not read Pool School, but you are incorrect. I HAVE read Pool School many times and I use Pool Math...

I was broadcast scattering the stabilizer into the water (per the bottle instructions). Hadn’t heard of the sock method until it was mentioned here after I had done the first 2 doses.

Re: Chlorine loss & pH level Yikes! So sounds like I need to add a LOT more stabilizer!! But do I need 24 or 42 oz (via measuring cup)?? Sorry on the bleach %, it’s 8.25 Certainly not saying algae isn’t possible with my pool, just less likely (as this is what I’ve been told by many...

Hi mknauss. Thanks for the reply and additional info. Understood on not seeing algae, all I'm saying is that my understanding of algae and the type of pool I have, etc. I have always been told that's unlikely. At this point, I have added about 18 oz (by volume) of granulated stabilizer...

Hi all, Thanks for all the replies. I am unable to do an OCLT test as I won't be home tonight, but I did this for all intents and purposes last night as I took a reading after the sun was off the pool and chemicals hadn't been added and FC was 6.0, then did it again early this morning and it...

Hi. Thanks for the replies. I haven’t tested CYA since yesterday as the last suggestion I received was to wait 2-3 days, but I can test later today as I’m not home at the moment. If 1.5 FC loss is ok over 12 hours, that would mean I’d lose 3 over 24 hrs, which is about 44 oz daily to maintain...

sorry, let me clarify, I raised it to 6 last night around 6:00 PM (after having added the stabilizer during the afternoon). it was at 4.5 at 6 a.m. today and now at 3.0 at 1:00 pm. Not sure what could be in the water as all other levels are good, it's a FG pool with no stairs or other places...

hi. i'm targeting 40-50 CYA so was shooting for 6 on FC. I added bleach to bring it from 4.5 to 6.0 this morning, but it continues to lose 1.5 FC every 12 hrs

Mid day update: FC is now at 3.0, so has dropped 1.5 since 6:30 this morning (6 hrs ago). Thinking stabilizer isn't enough yet?

Hi all. Morning update: FC is at 4.5 @ 6:30 a.m. this morning, so only down 1.5 from where it was at last test yesterday at 6.0 @ 6:30 p.m.

hi. not sure how much stabilizer in weight. I've done those 2 doses of approximately 6-8 oz in volume. just re-tested: FC was at 6 which is good. CYA did not appear to be much different, the dot was harder to see but still visible even with the tube filled completely.

Thanks, I hope you're right! Latest FC was 3.5 so did another dose of bleach to bring up to target. Will test FC again and CYA in a couple hours to see if there is a change.

UGH!! I must've misunderstood, as I thought people were telling me to re-assess CYA after an hour or so of the treatment. I REALLY hope I didn't over do it now. :brickwall::brickwall: I think my CYA was high last year due to / before I switched from Tri Chlor to Bleach, but as I mentioned...

definitely a frustrating test, and level to balance (as mentioned, last year was sky high and this yr is on the floor!). ugh. just re-tested. FC was at 3 so added another 40 oz of bleach to try to bring it up to target. unfortunately, no change in the CYA, still filled the vile and could...

woodyp, I wouldn't say I trust my PS CYA reading, but then again, I don't trust the one in my tftestkit either, given how subjective it is! That said, when I did my CYA test, I filled the tube and had no more tube left to go, so it was at least 15-20 if not lower. s_vidden, "Excessive rain...
