I've already read several posts about cloudy water. Using TFP articles and the pool calculator, I've concluded I need to raise FC to 12 and do the overnight FC test for 2 nights. Last night I had no measurable FC loss. I'm trying it again tonight. I've been running the filter on high for a day and a half now and brushing the sides. The water is starting to look more clear. I saw some posts that said it could take a week to clean up the water (and some backwashes).
The good thing is that it looks like I'm making progress. My question is about something I'm reading in the manual with my Taylor test kit (K-2006) and it says I should superchlorinate to 30 FC to kill algae. Is this just their way to get your FC high enough to do the job without having to think too much about your CYA level, or are there reasons I would want to raise FC to 30 instead of 12 (CYA is currently around 30).
I didn't have noticeable algae on the walls (I'm sure the dark pebble finish makes it more difficult to see), but the water was murky and I had some "suds" forming on the top.
If I have no FC loss tonight, am I on the right track just keeping the filter going for a few more days (and backwashing) to finish, or are there reasons I should be trying to shock at 30 as Taylor's book recommends?
