At the end of last year I had a pretty bad algae problem. Seemed to get rid of all of it (or almost ) before I took it down for the winter. I put it back up a few weeks ago and I have noticed it is just a little cloudy... I can still see the bottom though! Was not sure if this is something I should be concerned about... I dont seem to be having a problem holding the FC where it should be. I did just vaccuum the bottom and brushed the bottom and sides and I shocked it using 6% bleach. My question now is... should I do something more? I bought some Clarifier and some AlgaeGuard. i am not sure if I should use one or both of these and at what point? Do I have to wait for the fc to come back down? (b/c I just shocked it?) On the algae guard it also says intitial dose 1 gallon per 50,000 gallons of water and maintenance dose 1 quart per 50,000 gallons of water. My pool holds approx. 4400 gallons, so I am not sure how much of this I should use.
