We've backwashed twice I think so far, so about once a day. CYA has not fully dissolved yet so I haven't checked the level. Out of three socks, one has dissolved, the second was moved from the pole you see in the right side of the pic to the skimmer basket, and the third sock is still hanging from the pole in front of the return. The skimmer sock should be dissolved by this evening so the third sock will be able to be moved to the basket. We could only get one in there at a time without disrupting the flow. But since FC is holding well, I'm not too concerned about it.
Lots of patience at this point! Go, filter, go!
