I Want To Be A B/b/b Convert!!!

Another Borax question.....You say to add a box...the box I have is a 4lb. + box. Just put the whole box in???

[mwsmith2]

Yup, the 4#+ box is the standard size. I'm going to guess your pool is around 24,000 gal, so you might want to start with 2 boxes. Adding thru the skimmer is fine. You can broadcast CaHypo at the same time, but be aware that the CaHypo may make your pool somewhat cloudy. Plain, unscented bleach is the way to go if you want to impact the clarity the least.

Yup, put the whole box in through the skimmer with the pump running. It will take some time for all to disolve and circulate through the pool.

My 16x32 vinyl IG was in similar condition with pH this spring, and I initially added 16 lbs of Borax and 6 lbs of Baking Soda to get my pH up to 7.4 from below 6.8. I did this over a series of 3-4 days. The good thing is that now my pH never moves off its current level and has been steady for the last three months.

At the same time, I was adding bleach to bring my Cl up to shock level. Unfourtunately for me, my CYA was over 150, so I needed LOTS of bleach. I went through at least 15 gallons in a span of 4 days before my pool was clear. (My SWC was also running at the same time) You'll need to test at least twice a day for CL level with a good drop based kit. Add the bleach as many times a day as it takes to maintain the shock level (KEY POINT!!).

You'll want to be very dilligent to monitor your CYA and pH levels if you're going to keep using the pucks.

Ok....added chlorine this morning and a box of borax. 4 hrs. later tested water again. These are my results:

FC = 3.0 or >
CC = 5.0
TC = i'm guessing here 8.0????
pH = 7.6
Alk = 100
Cal = nothing???
CYA = <20

So, since this morning, pH and chlorine levels have gone up, Hardness has dropped to nothing and stabilizer is still the same?? Does this sound right.

dog,
What are you testing with? I ask because your chlorine and calcium hardness results are both a bit odd (that's a very high level of combined chlorine and hardness can't change that much that quickly, especially in that direction and especially because you added calcium yesterday).

[2dogpool]

just bought a new drop test kit yesterday. I understand the reason for the drastic change in the chlorine level......I threw 2lbs. of granular in 4 hrs. ago. I don't get the hardness level dropping like that. I also put a box of borax in 4 hrs. ago. Actually almost 5 hrs. now.

[KurtV]

It's not that your total chlorine is so high that makes me wonder but that the combined chlorine is so high. By the way, you're correct that TC = FC + CC.

Who makes the test kit? What kind of chlorine test does it have (OTO, DPD, FAS-DPD)?

[2dogpool]

KurtV - It's an AquaChem test kit......I know....not the best but all that K-Mart had. I just retested the cl and hardness. The Cl appears to be a bit above 3 but not to 5 and after waiting a few minutes for the sample to develop it really doesn't change. So I guess, in all actuality, the CC is the same as FC??? Is that right?

Now the hardness testinstructions say to "add 2 drops of solution A....sample with turn violet if hardness is present." My sample does not turn violet. However, it did this morning. Then I'm supposed to ad solution B in drops until the sample color changes to blue. This morning it took 3 drop to change to blue which made the hardness 150ppm (multiply # of drops by 50). This afternoon I had to add 36 drops to get the sample to turn a very pale blue. So that would make my water hardness 1800ppm???? This can't be right!?!?!?

Hi,

You mentioned you have a heater - if this is the case, you do need calcium in your water. Your liner doesn't need it, but your heater does. The range is 200 to 400ppm I believe. I have been keeping mine at about 170 and I'm in line with the Langelier Saturation Index so I'm not increasing to 200 or above. Here's the link: http://www.advancedh2o.com/technical.../langlier.html

The others on the forum are much more knowlegable about the other numbers so I will leave that to them.

Hope this helps!

Not to sound too stupid but......no, doesn't help at all!!! What is the Langelier Saturation Index?????
