I'm a pool newb so maybe this is normal, but I've recently completed a Baquacil to chlorine conversion and I've been adding CYA to the skimmer to bring the level up. I did a sand replacement last night and added some CYA afterward. I noticed there was a decent amount of CYA granules exiting the return jet. If this is normal, how does that happen? Basically, it'd have to bypass the filter lateral fingers, right? If this isn't normal, what could be wrong? I checked all of the fingers in the filter and they were fine, none were broken. I appreciate any advice, thanks in advance!
