I'm a failure for father's day

You want to bring it to slam level every few hours. If you are only losing a couple of ppm of FC every test then you are ok, as long as you bring it back to slam levels. For example, you test and add FC to reach 12ppm at 8:00 in the morning and test again at noon. The noon test says you have an FC of 10 ppm and you add enough FC to bump it back to 12 ppm. You don't want to skip adding FC at noon. Continuing the example if you did not bump up the FC at noon and at 4pm your FC test was 8ppm, that makes 4 hours you are below slam level. You are still killing algae but at a much slower rate.
If your pool is clear and you want to swim, then it is ok to swim at slam level or below, and when you are finished bump the FC back up to slam level.

You do want to make sure to take advantage of the overnight hours when the sun is not degrading the FC by bumping the FC to slam level at dusk.

Others have told me since my slam level is 12, I should never allow it below 12 or I'm not slamming. If 12 matches the SLAM level on this chart that is correct

For example, if I take it to 12 right now and check it in 4 hours and it's 8, I'm not slamming, right? Yes, that's correct. From a practical point of view our experts advise every 4 hours to sort of optimize reagent consumption with SLAM effectiveness. If you're not concerned about the reagent consumption it doesn't hurt to do it more often. But in most cases every 4 hours is plenty.

And If I'm losing 3ppm every hour, after 4 hours it would be 0 fc? If the loss is completely from algae and organics yes. Sunlight degradation is reduced as FC level reduces.

I hope this clears up the confusion. We have a lot of people here that try to help all with best of intentions. Some based on their experience and some that are qualified as experts. When I was new and got conflicting information I deferred to experts and understanding everybody was doing their best to help.

You've made great progress since I saw your earlier posts and it was very nice to see the kids enjoying the pool! They're very fortunate.

Thank for clearing some of that up. So I'm keeping it at 15 because the lose is enough that if I go a few hours I am under 12.

My lose is much more during the day. Over night I see 3-4 ppm loss total

 

[Bille]

11:30am tft: 11ppm taylor: 11.5

I checked cya since adding 1 pound on Thursday. It pretty much disappears around 25, but I can faintly see it until about 20, I'm assuming its 30. Maybe I should add more?

 

[setsailsoon]

Sounds like 30. If it were me I'd finish the SLAM before you add anymore. Last I checked you were losing 3-4 ppm at night so you still have a lot of algae. Try to maintain as late at night and early morning as you can so you're not fighting the sun more than needed.

 

[Bille]

I check it a little while ago and it lost 4ppm in 1 hour. Is that even possible? 3 days into this slam, I got frustrated and removed the latter. No one uses the latter anyway there are steps and I read algae can hide in it.

Also, I got in and brushed the walls as best as I could. I noticed the floor on the deep end is slippery, not so much on the shallow end.

While brushing it got cloudy along the walls, like what you see what you squeeze the cya sock kind of cloudy. Overall, the pool was still very clear after brushing, but there was debris floating, either from the walls or the latter removal, or both.

So I put in 2 cups short of taking it to 15, was too wet to go inside and get a new bottle.

I'm down 1.5 gallons of 12.5% today so far. This is day 3, if this continues into Monday and I have to go to my office for 8 hours, what do I do? Should I just shock it at like 30ppm and hope it doesn't come down before I get home from work?

Sorry your having the frustration. Yes, it's definitely possible but very unusual for a pool that's followed strictly the SLAM process. From your previous posts it looks like there were at least a few gaps in this. You can continue your SLAM with 8 hr gap during the day. More frequent addition isn't required it just speeds things up. If you stay with SLAM procedure you should be much better by Monday. Any chance you have ammonia from the kid parties?

Chris

 

[setsailsoon]

PS, no I would not go to 30 ppm, that level is way to high and could cause damage. A few parts over is OK. Keep up the more frequent testing 'till as late as you can. If you have ammonia it will take a LOT of chlorine to resolve.

It's possible, I didn't blow out the lines last winter, which I think can cause ammonia. But I thought ammonia came with cloudy water? My water is so clear, it almost looks like there is no water in the pool

Also, the couple of times I check CC it was 0.5 or less. I think ammonia makes CC high?

 

[setsailsoon]

There are several sources of ammonia. Most frequent is from degradation of CYA when pools are closed for winter. Since you have drained and refilled your pool it would be from something added. Or urine from "couldn't wait" which causes increased FC consumption and this results in CC as chloramines that cause the strong chlorine smell.

I was just speculating on the high FC loss after 3 days. Regardless of the cause for the high FC level just keep SLAM going.

I'm gonna kick those kids butts.

 

[setsailsoon]

Ha ha ha!

 

[Bille]

Since I removed the latter and brushed the walls, its been 10 when I check it every 2 hours, and I bump it back up to 15.

 

[Bille]

Still hovering around 10-13 every 1.5 hours from 15

I just checked the combined chlorine and it's less then 0.5. I didn't want to call it zero because there was a slight hint of pink and one drop cleared it.

 

[Bille]

Might be slowing down. Tested an hour ago it was 13. Didn't add anything, now it's 14. Test kits Tick me off. But maybe it was the latter?

 

[Mike1162]

Sounds like you might be getting there. After adding the chlorine are you testing to see if it actually got to 15 or are you just testing it an hour or two later? I wouldn't do that after every addition but maybe once or twice a day.

I was adding, then waiting 1-2 hours to test. How long after adding do I wait for it to show up? Right away would be good.

Edit: just tested again, still 14

 

[Mike1162]

I imagine every pool is different maybe 10 -30 minutes depending on the pool & filter/pump. Next time you do an OCLT add the chlorine then test it 30 minutes later & again in the morning. Good news seeing 14 again.

My pump and filter suck. I'm thinking about doing the overnight tonight. Maybe too soon but I'm desperate to end this

 

[Mike1162]

If you check it again & its at 14 then don't bother adding chlorine just check in the AM.
