Poly Quat 50 ???

[Makdaddy]

So I sent my wife God Bless her to the pool store to get some Poly Quat 60

She came home with Poly Quat 50 and it says Non-Chlorine

it says its not compatible with CHLORINE or BROMINE ??

Do you have more specifics such as the brand and full name of the product? There are a few Polyquat 50 products out there but I couldn't find any saying they were incompatible with bromine or chlorine.

Thanks. This MSDS indicates that the product might be a linear quat ADBAC in spite of their labeling it Polyquat. I can confirm this if you tell me the EPA Registration number which should be on the back label.

EPA REG NO 7124-19
EPA EST NO 7124-NJ-1


Thanks

Well how about that...the MSDS was right. The PAN Database entry shows that the primary ingredient is 50% of the linear quat ADBAC. It is NOT what we normally call Polyquat, in spite of what they named this product. It's an effective algaecide, but it foams especially when there is aeration. It also has a noticeably high chlorine demand.

Thanks chem geek

So if its gonna eat my chlorine is it ok to use after I shock?
or should I go find the PolyQuat 60?

You should probably take it back if you can and get Polyquat 60 instead. Look for the ingredient "Poly [oxyethylene (dimethyliminio) ethylene (dimethyliminio) ethylene dichloride" at 60% concentration.

Why are you getting algaecide anyway? Perhaps depending on why you are using it you could use this "PolyQuat 50" if for some reason you aren't able to exchange it (the Polyquat 60 is likely to cost more, perhaps 2-3 times as much, depending on what they charged for the PolyQuat 50).

Just looking to winterize the pool
trying to prevent algae on opening next spring
Pool is algae free today

Well, I'd see if you can return/exchange it. If not, then it is still usable and since the pool will be closed there shouldn't be any foaming since the water will be still. The difference would be that you'd dose it high and NOT then raise the chlorine. You'd have to depend on the algicide lasting longer through the winter. If you were to instead use the real Polyquat 60, then it is used with chlorine as described in this post.
