Do you think it's likely the ZeoSand isn't filtering enough / should I replace with regular sand? I would think the chlorine would kill the algae even if the filter isn't working properly (as if it were on recirculate basically) but that's just my intuition.Stay the course.........I can really think of no other option.
It was algae, so it was solid in a not-liquid sense, but not dense like rocks or anything. Maybe the consistency of mud?I wonder about the "sludge" talked about in reference to when he pulled the robot out of the pool. Can you share a little more info about that please. What did it look like? Was it solid?
I don't think so. I think it's slightly more clear, or no worse at the least. It's a little hard to tell because the lighting changes throughout the day, but I think the tile line on the spa steps, and the second step into the pool, is more visible than when I started.From the pics, it appears pool water is murkier now than before your SLAM start.......is that correct?
Did your solution make it all the way to/or/above 30? (You might be able to SLAM at CYA/40)I hadn't done a CYA test because I was still adding CYA (though it's almost all dissolved) but just did a fresh one. CYA looks to be right at 30, which is what I was shooting for.
I'm using the TF-100 test kit, which is a cylinder with a dot to look into. The dot was visible at a glance at 40, was not at 30. I could bump the chlorine anyway.Did your solution make it all the way to/or/above 30?
I can try that right now. What would the methodology be? Add chlorine to FC 16, wait 30 minutes, then test every 15? Alternatively I could do it tonight around 7, just to take the sun out of the equation.When you have bumped up to FC/16, how fast does it drop? 15min, 30min, 1hr?
That was the only picture I could find. If you still have your test solution, you can try filling part way inbetween 30 & 40, just for curiosity's sake.I'm using the TF-100 test kit, which is a cylinder with a dot to look into.

Retest in 15min, if it's not 16, raise it to 16, keep doing that until it holds 16 longer then 15-30min (when you can)I can try that right now. What would the methodology be? Add chlorine to FC 16, wait 30 minutes, then test every 15?
