I just got back from a weeks vacation in the islands, all psyched about getting the pool fixed up for the summer. To my surprise there was some green scum on the steps and the water is just a tinge green. I tested the Salt and CYA and everything was pretty much wiped out from all the rain and storms we've had over the winter. So, I've topped off the salt and CYA, will wait to adjust PH after the CYA is dissolved. Do I need to shock this pool? Or will adding the salt and letting the salt gen work more hours clean up this mess? Thanks in advance for your help! You guys are great!
