I'm not sure if it was coincidence that I had pollen and mustard algae at the same time, or if my pollen was really MA.
Here is that thread
It all started with an experiment to see how low I could get my FC without problems.
At FC around 7 or so, I got what I thought to be pollen. I felt it and it was not slimy, nor did the sides of the pool feel slick.
I should have taken a sample and poured some bleach in the tube to see if the "pollen" changed. That would have been a good idea.
Anyway, I'm on my 3 day of shocking.
I have done my best to maintain MA shock levels, but during work, the level dropped.
Last night I poured the last of my bleach in and got the level to 43 or so and the pool bottom was clean.
This morning I was welcomed by this
I have all of the pool equipment soaking.
On the top step was the surface dip net and under the net was this:
I tested the FC and used 83 drops to neutralize the solution.
That means the MA was able to grow overnight in water with > 41 FC.
The rest of the numbers are close to this:
PH 7.5 or 7.6
CH < 150
Temp- do not have a thermometer but it has to be at least 90
Is that nuts or what?
MA is bad mamma jamma!
