Ziss Adjustable Air Stone

Its a great little thing to throw in your bubble filter to make the bubbles smaller and not as loud you can just throw it on some air line straight out the box

Been using one of these for over a year as a diffuser with my CO2 system, very fine bubbles and no clogging yet. The ceramic diffusers are prone to clogging and some take more pressure to get a fizzle from them and some start to leak around the edges and produce larger bubbles. This Ziss is trouble free and produce a very fine mist. Give it a try on your CO2 system. It's a lot less money than the fancy diffusers and adjustable. Plus they work great as an air stone so buy a couple of them.

Great product!

So far, these are working well in my tanks. Small and mighty.

These are fantastic airstones
