Looking for input on 2 items that I have been pondering on.
OCLT during the daytime.
If my understanding is correct, the main purpose of the OCLT is to determine if an algae problem exists. I fully understand the reasoning for doing the test overnight to rule out sunlight that destroys the chlorine.
But lets assume that the pool owner has at least brushed the walls of the pool, and ( here I am assuming ) that if there was algae in the plumbing or filter, it would also most certainly also be in the water.
So what's to stop me from doing a 6 or 8 hour daytime test, by filling a clean bucket with 10 liters pool water, measuring the chlorine, and then putting the bucket away in a dark room ? Would this not server the same purpose as doing the test overnight ?
Bleach Drip Feeders
I have read a few threads on the forum about using irrigation drippers for a slow supply of bleach to provide the basic pool chlorine requirement.
However, wouldn't these drippers supply a constant ( yes, very slow ) supply ? I don't see the point in this.
In my pool, under a very hot sun for many hours a day, the FC drops from, lets say, 4 ppm in the morning to just under 2 ppm by late afternoon. After the pool is in the shade, I calculate the cal-hypo required and add to the weir.
So if I was to use a system that fed a very slow continuous supply, surely most of it would be partially wasted because it would be added to the water during sunny hours.
Or is it not a concern because the drippers only feed if the pump is running and most users run their pumps only after sunset ?
Personally, I run for 4 hours in the morning after sunrise to get the solar coils to heat the water, and then again 4 to 6 hours after the sun is down for the newly added chlorine to work.
