Petzlifeworld 4-Inch Round Air Stone Disc Bubble Diffuser for Aquarium Fish Tank Hydroponics Pump Ce

Good one met expectations, if you have bigger tank it will look very nice

The media could not be loaded.  works as expected, happy with the product, only downside is it is made in china

From the beginning, the bubbles were not coming in a spread manner. They were coming from only one side, in a line. Within a week I realized that it had developed a crack and that's why the bubbles were coming from a side. Now I have to discard it and get a new one

Good product I like it

This product sucks.. they will not even send the black metallic look frame, shown on the pictures.Most of the time you have to deal with damaged products!!!

The product is good but it requires a high power air pump.

Good

Pics on the product page are interesting but in reality product quality is not good at all. My first product was received damaged, it's connecting tube part was already broken. Got a replacement and this one works but again the joint part is very very weak, it can easily break if not handled carefully while connecting or removing the filter tube to it. Air bubbles also don't come out in large circles properly, plus very small bubbles. My existing air bubble maker worth 50rs does much better job of producing large bubbles in bigger area. Overall, not impressed. Cost is high as well fr this very poor quality item. Don't waste your money pls and grab a simple 50rs. one from the nearby shop.
