How much CH is in your fill water? If your fill water is not softened, you're adding CH every time you add water to keep up with evaporation. I'm in the Ft. Worth area and lose around 100 gallons per day from evaporation.

Hello all - I need to replace my timer setup and I'm not sure what to get. When our pool was first built 13 years ago, it had a SWG and an Aqua Logic AQL-P-4 was installed to control the SWG and handle our timer needs. We ditched the SWG several years ago (replaced it with a straight pipe...

Let’s try this...., my pool loses 500 gallons in 1 week due to evaporation alone. I add 500 gallons of water to bring it back up to the proper level. The water I’m adding has TA=300.

I mentioned the evaporation because for all that water I'm losing due to it I'm replacing with the 300 TA water (500+ gallons/week). I'll work on getting my TA down. Also gonna check the alkalinity with the water utility tomorrow.

I do monitor CSI using PoolMath (how else would I?), it changes as expected right along with my rising pH. Unfortunately for me, pH and TA are the biggest drivers of CSI for this time of year with water temp steady at 88-90. I can fill with unsoftened water (TA 300, pH 7.8, CH 150) but then my...

Like others, my pH is always on a quick rise. I lower it with MA to 7.5/7.6, within 24 hours or less it's back up to the 7.8/8.0 range. I'm fighting my fill water...., it's softened so I'm not adding any more CH but my fill water TA is 300 with a pH of 7.8. My pool is trying to reach...

Quick update here...., got my standard solutions and my speed-stir. All my reagents tested good as all my results matched the standard solutions perfectly. Also, when I did the CH and TA tests, the speed-stir results and my "manual stirring" results were identical so I'm confident in my...

Colormetric test strips? I tried one I picked up at Home Depot for the heck of it...., pretty much jived with my CH reading, quite different color for 250 vs 500.

Yep, I know how y'all feel about pool stores but 3 different ones getting close to the same results and I come in almost twice as high? It's got me wondering, that's all. All their other measurements were relatively close to mine, CH was really the only one far off. I'll order the standard...

Just curious if anyone ever validates their test results and how you do that...., standard solutions, have your water tested somewhere else, pool store, or? I'm doing all my own testing and balancing based on my testing...., but, since I had a weird CH increase (I replace all evaporated water...

I tested my softened fill water using the 25 ML method, still get zero CH so I think I can rule that out. One other unknown for me is the test reagents....., when I test using the reagents from my kit that I bought 7 months ago, I get CH = 375 and PH = 8.0. When I immediately test again using...

My CSI (from PoolMath) has been in the -0.15/+0.15 range all year so far, with most actually nearer to zero. I've been following test instructions to the tee, assuming all the test reagents are good, and believing all the results. Anything else I should check or any other ideas?

Do not have a speedstir but have been very consistent in doing the testing (repeatable results). Our re-plaster was completed mid-October of 2018. CH was holding steady at 300/325 or so until June, during June it gradually increased to 425 now. Have not had much rain in June but lots prior to...

Yep, I know about evaporation and the calcium/solids being left behind. Just don't see how it can rise at a steady rate when I'm not adding any more calcium with my softened water?

My CH level is rising slightly every week and I don't understand why. Any water loss is mainly from evaporation and occasional backwashing. When I fill, I always use softened water (no CH per my test kit), have had very little rain lately. Any ideas as to why my CH is on the rise? Our pool...

The PB must have stopped by today, when I got home from work there was a quart of Orenda SC-1000 Scale and Metal Control and a different brush (nylon/metal combination). They didn't test my water, I don't know about adding that stuff. I don't see how I could have a calcium issue, my fill water...

A benefit of having clear water is being able to see all the side and bottom surfaces of your pool. We had our pool resurfaced about 7 months ago with a Wet Edge Quartz finish and are now seeing several things show such as light spots, darker areas, patterned looking lines, streaking, and even...

Following this one....., I have 3 R-0014 samples, 1 that came in my TF-100 kit 6-7 months ago, 1 that came in a refill kit (exp 4/20), and 1 that came Saturday with other things I ordered (exp 12/20). I get 3 different pH readings ranging from 7.5 to 8 with these 3 R-0014 bottles. My FC is 5.5...

I store my test kit inside, the old bottle is red like the newer stuff. I will trust the new one and maybe order another (since I need a few other things anyways).

Been monitoring/adjusting pH with my TF-100 kit I got about 7 months ago. My original bottle of R-0014 is about used up so I tested using the new R-0014 that came in my refill kit. When using my original R-0014, I get a pH reading around 7.5/7.6 (no expiration date marked on that bottle). The...

Thanks sir for the reminder...., I will do that!

Good morning y'all..., after having our 12 year old pool refurbished late last year (new plaster, coping, more concrete decking), finding this site with all the knowledgeable folks, and taking complete control of balancing - here's my numbers. Everything has pretty much settled in and stayed...

Hello all...., new member with my first post. We just finished up with some refurbishing and upgrades 3 weeks ago on our 12 year old pool (new plaster/quartz, new coping, concrete decking replaced and expanded). Prior to the work, I was the guy who just loaded up the float with tablets...

Hey y'all! Been lurking around here for awhile and finally joined the group. Just recently completed some upgrades and refurbishing on our 12 year old pool, I'm ready take control and have lots of questions! Looking forward to learning as much as I can from this awesome site.
