Ch now at 300!

Great thanks. Wasn't that hard to find here online

I plan on adding approximately 7 pounds to our 3800 gallon pool . Current ch is 125... shooting for 225 or so. Thanks!

I found this online and is arriving tomorrow. I assume should be correct to raise ch?

Ok thanks for the info. What's also strange here in Vallarta. None of the pool companies sell calcium chloride or even test for ch. With 95% of the pools here being plaster concrete and the city water being approx ch 125, why are there not boatloads of plaster grout problems on the tens of...

One thing that is perplexing me .the fact that in this city everyone (including this house) battles major scale calcium deposits on everything the city water touches, from taps to toilets. So can some more knowledgeable then me explain a low ch reading of 125 with the ongoing scale buildup...

I suspect a similar solution is probable for us as I highly doubt 4 months of 125 ch could cause such damage to pool specific properly cured and installed grout.

So to be more specific...is it possible with a ch of 125 to cause in under 5 months a case where new specific pool grout compound to begin aggressively deteriorating in this fashion?

Hi I'm just trying to rule out csi as source of this problem. I don't think it can be as grout is looking unstable only on a few areas I think more likely is error in mixing/application of the grout. Pool csi number is -0.44 (Target is -0.02). Ta 80 Ch 125 pH 7.5 Cya 50 Fc 6 Any input greatly...

Ha! indeed

update...I'm back to tfp water! yay. i did as you said that night and added bleach to slam level overnight ... now 4 days later tfp crystal is back..still was only running filter for a couple of hours a day. check out the additional photo i added. i believe that one night slam killed the...

Actually 1 border i only fly direct from canada typically but yes you do make a point worth considering. all joking aside could easily be an uncomfortable moment.

Not this time of year summer only. why, would they carry any smaller amounts if intended use is for de filters? Is it worth looking around for possible smaller bags of de in toronto or is 25lbs smallest Thanks

think my best option is to buy a 25 pound bag in Toronto and truck some back here next time. I found it here in toronto Diatomaceous Earth - Aquatech Store

Unfortuneatly around here all sand filters so not an option

just back from pool store an they only sell de in 50lb bags. so not sure maybe i will add a little clarifier i had luck with before, or do u think i should just leave it and eventually the pump running for a couple hours a day will bring it back to tfp water?Also i now know when guests are over...

Dang i am spoiled ! and i owe it all to this forum due to great helpful people like you. ok i just went to slam level for overnight and i will look for de in morn. approx how much do i need to buy? Also regarding slight cloudiness in first pic and like it was before crystal in second pic any...

OK thanks heres link to shared drive google..can you see 2 photos? I will check tommow if i can get de as well

Sorry i took pic but system wont let me upload? yes i mean slightly couldy and not tfp clear like before. i had a couple more people using it for 4 days then normal but fc i always kept 8. i have never used de but i have had luck with a couple capfuls of clarifier. particulaly helped when i...

Not sure why not crystal anymore. not bad but just not crystal like was a week ago. passed oclt. so no algea. i run pump approx hour and a half a day. with my pool size and pump filters entire pool almost twice approx in that run time. any ideas? Here's my numbers as of now. Fc 8 Cya 60 Ta...

Ok thanks ..a friend does testing occasionally and perhaps not tap rinsing. cleaned up perfectly with diluted muriatic acid. I love this forum specially for a first time pool owner in another country!

Anyone have this as well and what is solution? thanks!

Excellent thanks! That's pretty fast as i plan on running filter for about 3 hours a day in December when heater is on....that should be perfect. Right now 2 hours is working fine to filter pool only per day. December temps are roughly 77f days and 19f nights.

Was wondering as i still haven't figured out roughly how fast will our heater warm our pool if outside temp is 80? Heat siphon specs: Model SX3.25HP 208/230 60 . 80,000 btu Pool approximately 3800 gallons Thanks all!

Ah OK I get it. I just assumed due to all scale build up on faucets tap water would test high on a ch test. This forum is teaching plenty. Thanks!

OK thanks that's good to know so with my csi at -.13 I will leave it as it will increase over time. But i still dont understand how we battle calcium scale build up in the house on faucets etc when our water is only ch 150?

Right but I'm still only testing 150 ch for the municipal water in our house yet we still have massive scale calcium build up.. i still have yet to hear a good explanation regarding this... Incidentally my csi is -.13
