8. Pawfly 8 Inch Air Stone Cylinder Bubbler For Hydroponics Aquarium Fish Tank

Pawfly 8 Inch Air Stone Cylinder Bubbler For Hydroponics Aquarium Fish TankThis is an 8 inch by 2 inch cylindrical, highly efficient fish tank diffuser.

Because this diffuser is longer and covers a larger horizontal area, it creates a rather good stream of water to oxygenate the tank.

The amount of water put into the tank can be adjusted according to the kind of water pump pressure put in.
Because it delivers a large number of small bubbles, it is also very effective in making sure that the tank stays aerated the whole day.

Why we would generally recommend a person to buy a larger airstone is because the amount of bubbles that the product produces depends on the kind of air pump it is being used for. A large stone produces large amount and size of air bubbles only when it is fuelled with a more powerful pump.

But it is also more accommodating when one needs it to produce smaller and less amount of bubbles.
In this case, one can use a less powerful pump on the same airstone.

This sort of levity, however, will not be available in smaller airstones because in that case you will not have the option to produce large bubbles because it does not support stronger air pumps.
