Might not hurt to go through it one more time and keep hitting it with chorine heavy. Usually once takes care of it but mustard can be a problem to kill off. You also might want to consider switching guns ( cannons?:D) and giving polyquat a try. People have reported good results with it against mustard.
So, will the Polyquat 60 kill mustard algae? I was under the impression that it will not kill present algae, but help keep algae away if you use it, and don't already have algae?
If so, does anyone know how much I would need to use to treat an 11,200 vinyl inground pool with small amts of mustard algae, full of only grocery store chemicals per Ben's methods? I don't want to add anything that is going to mess up my water balance at this point.
Thanks
So ....come home from work today and no algae....plus the FC level is holding fine. So maybe what I saw this mornign was not algae....maybe it was pollen or something. I did buy a bottle of polyquat60...JIC...but I will not do anything tonight except monitor and add clorox...
we'll see.....:confused:
That's what I would do. I think a day or two more of chlorine should do the trick
wahoo---saturday morning and no algae:eek: I m going to shut off the filter for a few hours and see what it looks like later...but I really think it might be gone.
Follow up....
NO MUSTARD ALGAE!!!!!!! :D :D :D I must say that the Sodium Bromide did the trick...I used a one lb bottle in a 25k gallon pool and kept feeding it clorox for about 4 days and it was all gone....and before someone says ...feeding it the chlorine is what killed the MA...not true...I tried that for 8 or 9 days before adding the SB with no luck. YMMV...but it worked for me. And thanks Evan for all the help....much appreciated. Hope your own pool project is on the up turn!!!!
Glad to hear it. IMHO, chlorine is STILL the best first attack against algae but mustard algae can be stubborn and sodium bromide, if used properly, seems to give good results most of the time. It is a bit of work to do it right, however!
I think I got my algae problem because I closed the pool with some leaves in the bottom due to pump problems I had at the end of the year..then when I opened the pool I let it sit for a week without hooking the filter up thinking it was still april and not warm enough yet to worry about algae or testing...so it was my own fault for not being prepared for closing last year. Ben did SUCH a great job with my pool last year I was lulled into a false sense of security...:DQuote:
