I figured that out after the first time I did it and used a million drops I can see the 25ml sample would be more beneficial for doing an accurate CC count, because the multiplier is more precise, and CC has a smaller range.
I thought I read somewhere that CC was an indicator that there's still something in your pool that the FC was killing, so during SLAM if the water is still green, wouldn't I want to see CC above 0? Except for the first test after I started SLAM, when it was 1.0, it's been < .5, even 0, each test.
The pic on the left is before I drained and started SLAMing, the right is now.
So 3.5 days into this, the water doesn't look as clear as I expected. It's much better, but it still has a greenish tint to it. Is this the normal progression? I've brought the FC back to shock level multiple times, and I am checking about 4 times a day.
I'm also noticing, now that I can actually see the bottom pretty well, that there is a lot of brown stain on the liner. I thought it was sand, as my vacuum has been picking up some sand, but I can't brush it off. Any ideas on how to get rid of it?
OK so I passed all the tests. The water is clear (I can see the words on my vacuum at the bottom crystal clear). I think the problem is the dirty liner....that’s what’s discoloring the water. There are brown stains all over the liner. I thought at first it was sand....my vacuum even picked up some....but if I brush it, nothing comes up so I think it’s a stain. Any way to clean this with water in it?
