Is a partial drain *really* the only way to reduce a high CYA? Here are my current levels (using the TF 100 Test kit)
FC 33, CC 1, TC 33, CH1375, TA 120, CYA 100
I don't have a ton of algae, but have been struggling all summer to get the pool clear (didn't help that pump broke and had to be replaced). I've been using trichlor tabs and Leslie's Power Powder plus to shock the pool -- after really reading up on this site I understand that's not the way to go.
I don't have a drain in my pool, so will have to pump water out into the storm drain -- something I'm really not crazy about doing.
Will lots of direct sunlight reduce CYA? It's been an atypical summer here in Central Texas -- lots of rain and overcast skies.
Thanks for any help!
