I saw a pool pump room that had a tube or container on their piping where they could simply put a canister (liquid) up to it, open a valve, and it would suck the contents into the flow into the pool. Anybody know that that is called, or where to find one? During peak heat, my chlorine level runs low and I want to put an 'extra' quart/half gallon in to boost things back up, but I don't want to pour it directly into the pool.
Looking for a way to add chemicals into piping system adhoc

For chlorine to be sucked into the system, it will have to be introduced on the suction side of the pump. That's easy to do; you can replace your pump's drain plug with a valve and tubing. See the photo below.
But if you introduce chlorine there, it'll go directly into the filter where it will react with the trapped organics and produce chloramines, and then it will continue, at very high concentration, through all the rest of your equipment. That might not hurt all of it, but it certainly won't help any of it.
Why don't you want to pour it directly into the pool?

Use the search bar for Stenner Pumps and you will get lots of discussions. Note they are more of a timed release and do not operate exactly how you describe.
A stenner pump or pouring chlorine into your pool is certainly the preferred method for adding liquid chlorine for many reasons including the longevity of your pool equipment. Why don't you want to pour liquid chlorine directly into the pool?

I agree the suction side of the pump wouldn't be a great idea. I put it directly into the pool today, but sometimes the pool is occupied, and I don't want to clear them out.

Adding chlorine through a 1/4" tube at the equipment pad doesn't seem much different from pouring a 1/4" stream of it directly into the pool in front of a return.
Consider browsing the Pool Care Basics and other Pool School articles, and maybe watch the FC/CYA video. If you maintain your pool with the TFP method, you can just add extra chlorine before there's an unusually heavy bather load, so you won't have to figure out how to add it while people are in the pool.

thanks to all. The venturi injector was what I was trying to remember. Currently I am injecting the chlorine into the pool with a rolo-chem pump controlled by an intellichem. (and acid with a stenner pump) The issue is the rola-chem is under sized, and on these 100 degree days, running 100%, it falls behind. Currently, I raise the orp setting to get a running start earlier in the day, and hope it is enough to make it through the dip in the middle of the day. The real answer is to buy a higher output rola-chem pump, but I was hoping for something cheaper than $600 since the existing one is sufficient 95% of the time. P.S. I looked into buying a replacement motor and gear assembly for the rola-chem ($200), but the larger motors all seem to be out of stock. thx again.

What CYA level do you have in the pool water? If you abandon the ORP, you can take it to 50 ppm or so and likely reduce the FC loss substantially.
Are you sure about the SWG? This sounds like a public or hotel pool, maybe a swim club or YMCA?
CYA is 13. and yes, local neighborhood cabana club. all volunteer run. Its my turn for a two year stint now. The pool is 113K gallons.
