Is this from adding baking soda or could this be something else?

[NSBFAN]

Hi all, I found this sort of "cookie" like puck in the pool pump filter basket (the one just before the pump. It was in one piece about the size of a sandwich cookie. It has a smooth consistency, broke up pretty easy, and isn't real gritty. I'm wondering if this is baking soda that for some reason congealed together in the basket. Or could it be something else like my pool finish or something? It's the first time I've noticed such a thing. When I add baking soda, I distribute it then use my wall whale brush to try and dissolve it. My pool runs a Kreepy Krauly sandshark cleaner most of the time with the skimmer on and main drains off.

If it's baking soda, is there a better way to add? I last added a large box as my TA was at 50. Any thoughts are appreciated.

It's not baking soda, but I don't know what it is.

Looks like a chunk of british candy called: Tablet.
Take a bite.

haha kidding....what does it smell like?

 

[NSBFAN]

It has really no smell at all. When I smush it between my fingers, it's a smooth feel, not a paste but like a very fine compound. Hard to describe because there's not any perceptible grit to it. Very bizarre.

If you put it on something that can get a little muriatic acid on it and put a little MA on it (very carefully so it doesn't get on things you don't want to be burned by acid), does it do anything?

 

[NSBFAN]

You know, I'd give that a try but unfortunately, I took pics of it then threw it out a few days so. So far haven't seen another. I wonder if it could be some organic material?

You got kids?

Find any weird wrappers in the trash?

Looks like store quality edible item. Probably a bird dropped it or something like that.

I swear it looks like a cookie -- you can see a layer on there that looks like icing. Check to see if anyone was eating in the pool and thought the skimmer was a great place to store the leftovers!

 

[NSBFAN]

LOL - I appreciate the comments. My pool is covered with a screened cage, so no bird. No kids around. Plus, this was NOT in the skimmer basket, it was in the sealed pump basket. So it would have had to be sucked up by my sandshark and I'd think that would pulverize anything. I think its some material that was loose but bound together in the pump basket. Just weird.

Have you added granular CYA via the skimmer before?

 

[NSBFAN]

I've never added granular CYA.
