Startup SWG chlorinator salt for new pool

[brendio]

i just tested at 4pm and for the first time i got target FC 35, i been testing every 2 hours and each time is been down, but this time its bang on target, the Chlorine is good is dated just a few weeks old bought it today,

as for pool math i have it set to , Bleach, 12.5% i think thats correct ? the Chlorine tub says 130g / L available chlorine as Sodium Hypochlorite

130 g/L is actually 13%. 12.5% in pool math should be close enough

you should be brushing anyway

i admit i been a bit slack on brushing as it was such a faint stain , 99% of the pool looks perfect, kinda nothing to brush i did do some but not every time i added, but i get it, i should have been doing more, but right now stain is gone i cant see any stain now............

 

[FIESTA62]

actually 13%

yes of course i missed that, i will change it

Looks like you're getting there, good job!

And keep brushing to make sure that there really is no algae left. There also are some hiding spots like behind the skimmer weir, in the vacuum hose, behind the lights where algae sometimes keeps lurking around. If there are any pool toys, then it might be worth checking them, old water in nerf guns, make sure all that gets a good soak with SLAM water. Removable pool equipment, stuff like that.

130g/L or 130/1000 = 0.13 or 13%

Edit: shoot, did it again. I answer a post and then three or four more show up in between. Weird.

8pm FC 36 used 10 ml test sample.....thats it for today will see what morning brings

 

[Dirk]

I think you're starting to see the SLAM working, if I'm understanding your reports. You were getting wild FC swings while the algae was active, now that it's dying (or dead) you're starting to see less FC loss between tests. That's what we were shooting for...

Sounds promising. Fingers crossed...

7.30 AM 10ml test FC 30 so lost 6 overnight, added 2 litre and will test every 2 hours today using 5ml testing

If you're bored... Some folks take pictures of their pool during a SLAM. Same time of day each day. From an angle that best shows the water's color and clarity. A pool's improvement during a SLAM can be very subtle. But a picture history can reveal color and clarity changes you might not be noticing...

 

[FIESTA62]

take pictures

well yep little bored even thought about waxing the GTO but nah not today....well thing is pool looks fine, i mean it really looks perfect , so i cant imagine it getting any more clear, but i had that FC6 loss overnight so i understand keep slam going, but i will go give it a brush now...

 

[Dirk]

Wax the goat or brush the pool? You've got it pretty rough. Though I'm having a hard time feeling too sorry for your woes...

 

[FIESTA62]

ok so 9.30 tested 5ml FC 33.......

now pool mostly in sun test at 1030 just 1 hour after last test now FC 27, drop 6, in 1 hour .....added another 2.5 litres...and yep brushed pool

i got new regent and powder, i will be using for future tests, in say 2 hours

 

[mgtfp]

Yep, there is still something consuming chlorine. Are there any hidden spots where algae could be hiding?

 

[Dirk]

Hmm, that seems like a lot in 6 hours. Maybe some testing errors? If not, keep doing what you're doing. Just be sure to test consistently. Use the same exact method from test to test. Rinse everything well (with the sample pool water). Take your sample pool water from at least 18" below the surface, from the same place in the pool each time. Keep the reagent perfectly vertical when dropping. Etc. Try to do the testing exactly the same each time. Other than that, ya got the green so do your theeng.

testing errors?

i am doing exactly as u say, same place in pool for test water, elbow depth, 5 ml sample, rinse everything with pool water, drop bottle vertical and drops as even as possible, using speed sir, now new regent and powder, and chlorine

ok so tested at 1030 got FC 27 pool in sun now, added 2 litre.....test 12.45 FC 30 add 2 litre

see pics of pool looks great, got wife to look for stain just in case i am going mad and she sees nothing but clear water

 

[Dirk]

Sounds good. You just have to keep going until the FC holds. Don't ignore some of the other tips you were given. Just because the stain is not visible anymore doesn't necessarily mean you're free of algae. When you brush, it gets set free into the water. And it could be hiding elsewhere (skimmer, light niche, vac hose, ladders, drains, etc). If the FC loss continues (more than just normal loss), you gotta start looking in the hiding places.

 

[wireform]

I still believe it's time to backwash the filter eventhough the pressure may not be high. That can be contributing factor your FC loss too..

hidden spots where algae could be hiding

well if there is i cant see it, just 2 lights and skimmer and as pool is pretty new its all looking very clean....
