No chlorine

I have had successful results wa-a-a-ay past 25 ppm. (70 ppm results but couldn't figure how to verify it)

I think the precision starts to suffer but 28 ppm will be no problem

Will the SLAM process take care of nitrates?

Nitrates are not something you need to test for in your pool.

Guess that’s all the more reason to stay away from the pool store bs that they tell everyone.

Started my SLAM process yesterday morning, I check levels about every 2-3 hours and brought FC up to 28 each time, according to chart. Brushed and vacuumed pool in the afternoon and did a final FAS-DPD test last night around 9:30 and brought FC level back up to 28.

Pool looks great this morning and no signs of any algae on floor. FC showed 24.5 which tells me I lost more than the 1 ppm over night so I will continue to test and increase the level to 28 throughout the day. Hopefully I’ve done this all correct so far…..

My question is on the test at night, do I bring FC back up to 28 (if not there) or if it’s at say 25, do I just leave it there and go of that for my morning test? Anything with reading of 24 or higher would mean a passed test. Please advise. Thanks!

Sound like you did it just right.

No need to return to SLAM value for the OCLT. You are simply measuring the difference between the two FC tests.

If you fail, then return FC back to SLAM vale after the AM test.

Ok so do I continue to test and bring up level to 28 throughout today because FC level will obviously drop due to sun or do I just leave it and test tonight and if it’s at 20 then use that for my morning test? Morning test would fail if below 19.

No need to return to SLAM value for the OCLT. You are simply measuring the difference between the two FC tests.

So let your FC come on down during the day, perform the OCLT at whatever FC level you end up at tonight. You have it described correctly in your post above.

Ok perfect, thank you!

And if I fail test tomorrow morning then that is when I would bring level back up to 28 and then do this for each day until test is passed?

 

[duraleigh]

Correct. Might be a good idea to re-read the OCLT article and the SLAM article.

The SLAM article has three specific criteria for you to meet that marks the end of the SLAM.........sounds like you are close.

Someone call me? Looks like it. Yes, pool store (yuck, can't even believe I said that pfffft) BS.

And if I fail test tomorrow morning then that is when I would bring level back up to 28 and then do this for each day until test is passed?

Re-read the SLAM process. Print it out, read it three times. Keep it in your back pocket. Link-->SLAM Process

Check and replace your FC to 28 every couple hours during the day. SLAM will go faster that way.

Sincerely,
Pool Stored.

You can also use 5ml of water for the FC test instead of 10ml. This way one drop of reagent is 1FC instead of 0.5. Pretty helpful when running high levels. This is what I do when measuring my FC but you might want to stick with 10ml for the OCLT.
