But it will let me buy other poolrx stuff on there just fine.

I'm using the baking soda and liquid chlorine method, (and a couple other things from pool school) and am a new pool owner. Should I have this on hand just in case I get green water?

If you lookup the MSDS for PoolRx you would find it contains 35%-50% Copper Sulfate. Copper will stain your pool and turn blonde hair green.

Suggest against anything but chlorine and acid/base.

That was my fear. The one thing I have learned so far is that companies love to sell excessive chemicals. I just woke up so am groggy and trying to sleep more but also hate to miss a good deal. I'll skip for now. Thank you!

The plastic container it a piece of copper and minerals. The refill is the minerals replacement. I had some copper pipe in the garage, cut in pieces and put it in my basket where the PoolRX basket used to go. So, I don't buy the PoolRX anymore.
They recommend replacing the basket yearly and replacement minerals after 6 months.

Or, instead of spending a lot of money on small prepackaged containers, buy it in bulk. It is used for a variety of things like root killer, fungicide, etc.
Here is a 10lb bulk order for only $28.

A little research says that this copper is chelated (whatever that means) and that at normal pH 7.2-7.8 will not stain your pool or clothing, and will reduce chlorine demand.
Also the cage unit is on sale as well
