To Shock ----- or NOT

[Jakebear]

I don't think you mentioned any of these additional items (worms, bird poop) in your original post so that may have influenced our responses. With all of that junk, yes shocking would be playing it safe, though if the CCs were near zero and with extended exposure of chlorine over a long period of time, the risk is low. I'm certainly not going to get in the middle of a domestic squabble!

I guess I assumed that with a mesh cover and birds that fly ---- well, we all know what happens next. The worms --- not many, occasionally commit suicide and get sucked up when cleaning. I guess I would feel better if shocking so I appreciate the help. With the CYA at ~30, going up to 12 on the FC should be good.

Thanks to all for your opinions, BUT......
What about the dead worms that have been removed throughout the winter and how about the bird poop that ends up on the mesh cover and then it rains and migrates into the pool????

Seems like this isn't much different than having a "solid" accident from a child which most of you have stated in the past-----"SHOCK, SHOCK, SHOCK, Better safe than sorry". "Kill the bacteria"!! Somehow I fail to see the difference.

Jake, while I don't think it's neseccary to shock without a CC level - if adding a couple of gals. of bleach will allow you to sleep better or keep you from being 'distracted' at work, shock the pool! As long as you don't have CC from the worms and other 'ick' that may have entered the water over the winter, you've sustained enough FC to deal with it (remember that the 'ick' doesn't 'spread/ grow' as well in low temps and that CL does a better job at lower temps). However, if for 'peace of mind' you want to spend $5, it's not going to hurt anything and you can start enjoying the pool without those nagging thoughts...

Well the score is 7 "no need" and 2 "well maybe".

To avoid a "silent spring" I will spend the $5 for some extra bleach and make the "better half" happy. As the "winter" keeper of the pool, shut down, winter maintenance, and start up are mine. She will take over from there.

Thanks for all the opinions. At least I "won" ------- (till she reads this )
