Hello everyone!
Last year about this time I was struggling with an extremly high CYA level and mustard algae. Things are a bit opposite this year!
Here are my test results that I did June 2nd:
CYA - 10-20
pH - 7.5
FC - 2.0 ( I kept it this low since my CYA was low...probably not a good idea I know)
CC - 0.0
TC - 2.0
Alk - 70
Calcium - 1400!!!!!!
My pool has been a bit cloudy lately. I did the calcium test TWICE, but I really don't understand HOW it got THAT high. I used some 42% calcium hypochlorite when I ran out of liquid bleach, but I didn't use that much at all.
I noticed yesterday a yellow "film" growing on the bottom of my pool---but the water was still crystal clear yesterday. I brushed the entire pool, and as I did, a yellow cloud would appear where I brushed. Therefore, I assumed I had mustard algae.
An overnight FC test revealed a loss of 1.0ppm cholorine.
I decided to go ahead and begin shocking the pool.
Also, I went to the pool store to have them test my water and they got some different results as me, BUT found my CYA to only be 17.
I bought stabilizer and an o-ring for my pool pump basket and that's it!! They tried to sell me Alkalinity increaser--and I was like...HECK NO! :lol:
These are the numbers the pool store got:
CYA - 17
FC - 9
CC - 0
TC - 9 (I'm shocking the pool so it's high)
pH - 7.6
Total Alkalinity - 81 (isn't this normal? Why are they telling me it needs to be between 125-150???)
Total Hardness (I think that's calcium) - 139
So I need to know what order to attack these minor problems..I am thinking I should go in this order:
1. Adjust CYA to approx. 30 so that the sunlight will not eat up all of my chorline. I am using the pool calulator now to determine how much to put in a sock and let dissolve!
2. Redo my calcium test... the pool store got a COMPLETELY different result than me.
Any other suggestions?
Thanks for your help!
