    Cal-Hypo

    Because of the recent scarcity and high cost of liquid chlorine I have been using cal-hypo for the last two years. I looked into converting to salt, but for various reasons decided not to. The only problem I had was the residue left from the filler even when I mixed it with water. I see now that...

    Maintain chlorine after power loss using cal-hypo

    As hurricane activity is ramping up in the Atllantic, if I lose power for extended time, can I maintain chlorine levels by adding cal-hypo to pool and brushing? I'm no longer using liquid chlorine because of cost and lack of availability. Even if I bought some liquid chlorine and dumped it in...

    Chlorine availabilty and cost - is it time to convert to salt

    Last year it was very difficult and expensive to get chlorine and I swtched to Calcium Hypochlorite. At the time it was about $150 for a 50 lb. bucket. Now it is $280 and who knows what it will be when demand increases at the start of pool season. I have an estimate of $2042 for installation...

    Shocking and water below 60 degrees

    In the pool closing sticky it states the following: "Two or three days before closing, I bring the pool up to shock level and hold it there until FC holds overnight (which it generally does right off on the first night). Then I let the chlorine level fall about half way back to normal levels...

    closing, algae, and chlorine use rate

    I made it through the summer with no algae problems with my new liner, but on returning from a 9 day trip on 10/17 thought I saw one fairly bright patch of yellow about the size of a saucer by the steps. It looked too bright to me for mustard algae and since we have a lot of yellow flowers near...

    Milky light green water after storm

    Yesterday my water and pool looked fine and my chlorine level was at 2 ppm in the a.m.. I added enough bleach to get it to around 5 (CYA 50). Early this a.m. we had some thunderstorms and a hard 3-4 inches of rain in a few hours. It came down so hard that the water was coming in faster than my...

    Where is my FC going ?

    This looks like an awesome site and I'm glad I found it. I've had my algae problems off and on over the years which I usually managed to deal with most effectively with copper algecide (I know that is a bad word here). However, the last 2 years I've had trouble with reading any chlorine on my...
