Lightbulb Upside Down Bottle Diffuser

Hello! I'm still new to this forum. But I like to read from afar whenever I found problem in my tank and it has been really helpful !

So recently I wanted to try CO2 for my planted shrimp tank. My tank are fully cycled.
(I never use CO2 because I read that it's sometimes could kill my shrimp).

Then I found this video.

At the first couple minutes. The owner of the aquarium using an upside down bottle to diffuse his CO2.
This is my first time seeing it.
He had some Styrofoam inside (I wonder what this is for) and how he stick it to the aquarium?

Will this method be safer for shrimp and fish?
Do any of you guys are using this DIY tools and have any experience with it?
Because I wanted to try it for my soon planted tank for fish and my current shrimp.
Both of my tank are 10 Gallon.

Buddy has to refill his bottles every couple days. Go with pressurized CO2 on two 10 gals and you'll probably have to refill the bottle every 6 months haha.

The syyrofoam is just to make the CO2 level more obvious, it sits on the water surface so moves up in the bottle as the CO2 is depleated. When it hits the top you need to refill.

Unless you have like 100 10 gallon tanks just get a pressurized system that can run both tanks, or two individual pressurized systems.

Here fishy fishy.
