ok i finally tested my swamp...i mean pool...with a dpd test

[fog80]

ok as of tonight my pool readings are:

fc-15
cya-45
ca-250
ph-8

the chlorine is pretty stable because i put in chlorine almost 24 hours ago and its still showing 15 (i think its higher but my kit will only let me go as high as fifteen)

the water looks pretty clear now, and my cya readings were up so i backwashed the de filter, bumped it, and backwashed some more and then added 5 lbs of fresh de.

i still have some dots (algae?) on the walls that wont go away though.

Lower you pH to 7.3-7.5 and the chlorine will be FAR more effective--and may just get rid of those dots.

BTW, you need to brush your pool everyday when you have an algae bloom--knocks the algae loose where the chlorine can get at it. That WILL get rid of those dots. Forgot to mention that-still rusty as I haven't even begun the pool opening process.
