We opened up our pool on Monday and it is a swamp. I've been delaying the SLAM because a local store was supposed to get in some more liquid chlorine and I was waiting for some more DPD powder to arrive in the mail. I finally obtained enough liquid chlorine but I got an email today that says that my shipment of DPD powder isn't supposed to arrive until Monday now. I have a tiny amount left but I doubt it will be enough to make it to Monday. Has anyone been in this situation before and could give me some advice on how to conserve the DPD powder? After the first day, could I just add the shock amount every few hours or something? I don't want to waste chlorine, but I can't afford to wait any longer to start this slam or I will have a harder time getting it to clear up.
