I just got new reagents for my test kit and decided to compare with the old reagents I was about to throw out.... ~2 Years Old Reagents (23 months) FC: 15 CC: ~0.5 CYA: - (Out of R-0013) pH: 7.5 TA: 90 CH: 175 ~2 Year Old Reagents (22 months - Never used) FC: 14 CC: ~0.5 1 Year Old Reagents...

Before buying a SWG I always found the chlorine test on the OTO to be utterly useless. Now with an SWG I found it to be really useful. What a surprise. Back when I was using LC I was running my pool hot (never believe the target). When your low FC threshold is 6 and your target is 9 the OTO...

I know, I bought the wrong stuff… the thing is Duda Diesel was supposedly out of small quantities so I order 3 years worth of Boric Acid (powder). Last year I tried to mix with water and dump in the pool… I don’t want to remember how long it took to dissolve…. Has anyone tried to use the sock...

Frequently someone folks come here and ask about UV and Ozone systems that some companies advertise as magical solutions. There is plenty of posts on TFP explaining why those system don’t work as advertised on pools. But there are not FDA warnings about not using those in pools and that is not...

So, I have seem someone posting that pollen does not consume chlorine. No point in point fingers… Chlorine attacks organic matter and pollen is organic matter, so seems to be reasonable to believe chlorine will try to destroy pollen and be consumed in the process. Now being reasonable does...

Taylor has that BS shelf life warning in their website and we all know most reagents last way longer than one year. So indefinitely. LaMotte has per a per reagent shelf life page. Do they use the same (or very very similar) reagents to a point we could use LaMotte’s shelf life to extrapolate...

My CH have been testing consistently 225 for last 3 weeks (opening day) what is consistent with what I had before closing considering drain/refill and my tap water CH. My CSI was around -1 what is mostly not an issue, except for my heater and I wanted to get my CH closer to 300 to bring my CSI...

I’m not trying to create useless discussion, but I can foresee this post being moved here, so saving some trouble and starting it here… We commonly see on explanations on why Ozone doesn’t work the factual statement that only inside the Ozone cell there is enough Ozone to sanitize the water...

I have a sealed 40lb bucket of HTH Cal-Hypo I brought last year (before TFP). It was keep in a dark place with temps around 60F. I already have few bags of Cal-Hypo "shock" that was my backup plan in case liquid chlorine gets hard to find, but now that I'm getting a SWG I'll have absolutely no...

So, last evening we got a thunderstorm with pretty intensive windy gusts... as result this morning the bottom my pool was about half covered with leaves and other tree debris. I skimmed about 5 lb of stuff from the bottom. That made me think about all the people down in Florida right now likely...

When people talk about how much work comes with a pool they are usually talking about how much work a non TFPC pool requires to care for it. For that matter I take an average of 10 min per day to care for my pool. Actually less than 5 min in most days, but then there are full tests, dropping the...

I'm not sure if The Deep End is the right place for this question, but it is somehow related to chemicals and it is definitively not a must know to own a pool. I have a bunch of Dry Acid that I brought when I ordered my pool (before TFP). I don't have a SWG, but I'm considering to get one in...

I got a LOT of rain over the the extended weekend, around 4" of rain. So, I got quite some dilution on my water and few things did not go the way I expected. On Thursday evening my numbers were: FC: 3.5 CC: 0.5ish (very light pink) pH: 7.6 TA: 85 CH: 150 ** CYA: 27 ** BOR: 40ish In preparation...

I recently got a Dolphin E10. It seems to do it’s job on my small pool pretty well. My only complaint is the length of the power cord. Have anyone come across an extra long replacement power cord? Some thing the the range 10-14ft would be ideal. No, I don’t want to use an extension. Yes, I...

When I ordered my pool, before finfing TFP, I also ordered a bunch of "common sense" checmicals.... well, sometimes common sense is misguided. Now that I know a little better I'm need to help to identify some of the Crud I got and find out how to dispose of it. From picture one (left to...

Yesterday I had several kids in the pool... in the evening water was clear but got 1ppm CC on when tested (FC 2, CC 1, TC 3, CYA 20 **, PH 7.5), so I added enough chlorine for 10ppm (I didn't use pool math all the way and didn't account for the 2ppm I already had, so ended up with 12ppm rather...

I read quite some interesting stories about how great a pool with borates feel, so decided to give a try. I’m going with Boric Acid for ease of use. Pool is quite new, but seems I got a good handle on chemicals. My CYA is intentionally low due to necessity of using trichlor in near future. My...

I have a Hayward SP1091WM skimmer on my AG pool. Frequently when my pump turns off the skimmer basket "floats" and after entangles with the skimmer weir preventing water flow into the skimmer and letting air into my system. I tried adding a medium (about 2" long, 1" wide and 3/4" thick) well...

I finish putting together my little AG pool last week and had my inspections done Today. I'm glad I found TFP before putting too much CYA in my water... BTW, now I also understand why my sister's 25+ years old pool needs so much algaecide. I already got a TF100 and I'm throwing the test strips...
