Good call. You're learning. That's the beauty of self-testing. You know when something is wrong.I must be doing something wrong. There is no way my FC went from 2ppm to 25 with the amount of bleach I put in. This morning I got FC 25 and CC .... Maybe I didn't use enough of the powder in last nights test? It didnt turn PINK, it was just pink
Good call. You're learning. That's the beauty of self-testing. You know when something is wrong.
Testing error is usually the cause of bizarre results when testing. Easy rule of thumb: if you have one or two undissolved granules in the mix after adding the powder, you have enough. They'll disappear when you start adding drops. Don't ask me how or why. It just is.
Yea the extra will help kill faster. Did you do the measurements at dusk and prior to morning direct light on pool? Sun eats CH. Algae eats CH. if sunlight is out of equation then you still have some organic or algae hiding in there someplace. But I use my pool while cleaning the startup crud stuff.
it was after dark, and just before direct sunlight this morning. without a doubt still some algae, i brushed a little before heading to work. the pool is getting more attention than my wife and kids these days. that's a LOT of attention!
The higher the faster it will go so..........................aim high!
