How much 6% bleach to put in an intex salt water pool 16' round by 42" deep to shock it?then how much to mantaine it, it isnt algea but my pump isnt generating chlorine I guess, after 6 days no FC? stablilizer in there and still nothing?I am thinking of just using st8 bleach now , forget the salt if it isnt working.
How much bleach to use?

Read up on how to shock your pool, and use pool calculator to determine how much bleach to use.

To know that we have to know how much FC is in it now and how much CYA you have in it. Knowing those things it's easy to use the Pool Calc to figure how much bleach to use.
Ok thanks I have added about 6L of ultra bleach and I am sitting good at 2.4ppm for FC but now my alkalinity is at 0ppm. Do I add some baking soda and how much ? also is all baking soda the same? as in doesnt have to be the A&H does it?

FC-2.4
TC-NOT RUN
PH-7.3
HARDNESS-290
ALKALINITY-0PPM
CYA-10
MY NUMBERS
AFTER ADDING ABOUT 6L ULTRA BLEACH THERE WAS ALSO 3 LARGE STABLILIZER PUCKS THAT HAD BEEN DISOLVED AND AFTER ADDING THE BLEACH THE PPM WENT FROM 25 TO 10
NUMBERS BEFORE ADDING BLEACH
FC-0
TC-0.2
CC-0.2
PH-7.3
HARDneSS-290
CYA-25
ALK-133
AND THERE WAS 2 BAGS OF SALT ADDED TO THIS POOL AND NOTHING GENERATING FOR CHLORINE
Hi katherine47:
What kind of test kit are you using? I'm a bit perplexed as to why your TA (Alkalinity) went from 133 to 0 and why your CYA dropped from 25 to 10 after adding 6L (~1.58 gallons) of 6% bleach. I use 6% bleach all the time and the only time my TA drops is when I deliberately take action to do that by using Muriatic Acid and aeration and that is a slow process. Bleach should not impact your CYA. With very rare exceptions, the only way to lower CYA is to drain & replace some water. Also, is "HARDNESS" Calcium Hardness (CH) or something else?

Hi, hardness would be calcium, and I had these done at a pool store today. testing my water before I added bleach as I had it tested the day before and was told there was no FC showing. And then also after I added the bleach.Is done by a computer read out.
I should add that my pool for now is completely clear , but I am worried it may grow algae if I dont keep the FC maintained.. the salt doesnt seem to be generating any chlorine or hasnt yet with the pump I have so I am just wanting to keep adding bleach to it and not rely on the swg to do what it should be doing.Maybe I have not ran the pump enough hr wise and that is why.. I figured 6 hrs would of been sufficient but maybe it is more like 15 hrs? This is only my 2nd yr with this pool and the first yr was nothing but a disaster with algae due to the pump being hooked up backwards and salt not generating chlorine .I dont want to buy a bunch of chemicals I just want to be able to keep the pool clean and be able to use it without skin irritants
You need to raise your CYA level. The recommended CYA level for a SWG is from 70 to 80.
Todays readings after running my pump all night for about 15 hrs
FC 8.0 HIGH but I guess that due to the liquid chlorine I had to add due to 0 ppm reading it is now reading 8.0ppm
CYA is now 50ppm
Alkalinity-185 ppm which is high, this was at 0ppm yesterday then I added 1/2c of baking soda to the water which today put it up to 185ppm so now is to high, will this dissipate or do I know need to use Borax? is it? Im new!

Baking soda will raise TA. To lower TA see the full procedure in the article in Pool School.
Swg new to me fc 0 i shocked the pool last night still green but not cloudy
