Larger than expected and it works great! We have an adjustable air line and we have it set at about half open and it is still a huge amount of bubbles. We have one in our 40 gallon and one in our 125 gallon and they both are perfect.
I've got 6 of these in 4 different tanks. My only complaint is they don't weigh enough to stay at the bottom of the tanks. I do believe pump size has a lot to do with these working properly. The smallest pump I'm using is for a 30 gallon aquarium. I don't soak them either. I'm very happy with them!!! They work better than the bubble wands in my opinion!!! Will definitely buy these again when needed!!
The 2 Penn-Plax Deluxe Bubble Disks were disappointing. Instead of sinking to the bottom of the aquarium, they both float on the surface. Even when I put them under the gravel at the bottom of the tank they still managed to work their way to the surface.
Well let it do its soak before use for well over time instructed and having issues with it staying on the bottom had to set quite a few rocks for it to stay sunken to the bottom and doesn't put out alot a bubbles
This bubble disk is cool. The fish enjoy it also. I would recommend this for ahyone who has a aquarium.
I soaked this per instructions for 15 minutes. When I hooked it up to the air line and put it in to the water. Only a few bubbles on a small edge came up. So I soaked it over night still did not work.
I see some of you got 1 small spot of bubbles. I got not 1 single bubble.
As with every round bubbler I have ever used, it requires suction cups relatively close to the bubbler base, on the air tubing line, to ensure it doesn’t float. If you have a decent pump, this bubbler will not stay on the bottom without one. I used 2, one basically at the base and one 6 inches down the line and adjusted the airflow to be lower to not disturb the sand. This bubbler is just the bubbler. No tubing, no suction cups, no pump. Intended to buy this as a stone to go under the volcano ornament in my tank, but this bubbler is “Large”, as described. Now we have a steam vent feature in the tank. The cory cats like to hang out in the middle of it.
Does not work like shown. Bubbles only came out one little spot even after letting soak.
