Desperate for answers on Mustard Algae

[waterbear]

Check my mustard thread...I used sodium bromide and kept the FC above 12 and had good luck. Before treating, I kept the FC above 10 for about a week, then added 4oz per 10gallons and added 1 galon bleach per 10k to kick the stuff into action. Then kept hitting the pool with clorox for 4 or 5 days to keep the levels above 12ppm...which BTW was alot more clorox than i thought it would be because the SB eats clorox like crazy. I seem to have kicked...no algae in sight for the 3rd morning....

I walked TundraSQ through the sodium bromide treatment because he had already put it into the pool when I started helping him. It really is more of a last resort measure when cholrine just doesn't seem to work. It isn't any easier or faster....you are just substituting bromine for chlorine. Polyquat is a good addition if the chlorine isn't working, also. The main reason that chlorine alone won't work is that the levels are allowed to yo-yo up and down from not putting it in often enough or perhaps from not having an adequate CYA level to protect it from the sun. HIt it hard and hit it often and brush, brush, brush and chlorine will usually do the job!

My water has looked nothing less than crystal clear, ever since this new liner was installed several seasons ago, and I only have Ben's recommended products in there. The average person would never believe there was algae in this pool, but would think it was just tiny piles of dust/dirt.

I am still keeping that CL up, and luckily, my schedule has allowed me to check CL levels very often this week. It is next week I am worried about, since I will be out of town. My roommate is actually going to be here. He is good for dumping in bleach, when told, but that is about all he knows about pool maintenance. PLUS, he is color blind, so I don't even know if he could test the chlorine levels!

I will try to get a quart of polyquat 60 in tomorrow. How long do you need to wait before swimming after adding a quart of that? I think a quart is for 10,000 gallons, can't remember. My pool is 11,200 gallons. Do I really need to get a second quart to make up for the other 1,200 gallons of water? I wish I could order it online from Leslies and get the cheap stuff, but I am racing against time, and want to get it in ASAP!

Well, I will see what things look like in the morning. CL was down to 13 when I just got in from work, so I will take that back up to 15 and see how much I drop overnight.

Thanks again for all the help!

I pay $20 locally for a quart of poly 60%. You can swim immediatly after adding it. A quart is exactly what you need to super dose your pool. They recommend 16 oz per 10,000 gal but I have never had problems because of adding a double dose.

I agree I did the same. I even added a 3 qt the following week b/c I was so paranoid the algae may come back. But it did not Can't answer on the swimming for sure though. I would swim but maybe keep any kids out for a few days.

If you have a Lowe's home improvement around they were selling a qt for $15.99 last season. Just verify that it is poly 60.

John, This could be hit or miss. All depends if it mysteriously multiplies everyday Each time my lawn is mowed I end up with small clumps of brown. But when I vaccum them out, they are gone! If you get the 2 qts in before you leave and your roommate keeps the cl levels up next week you hopefully should be good to go. Unfortunately Mustard algae is more of a pain in the butt then the green algae but you'll get there.
