Exactly what the title says, what do you think and why ? Do you just like the look? Is there a huge benifit from it ?
You should always have an Airline check valve in the lines to prevent water from draining. they're CHEAP:One person pro bubbles lol. .....
One reason why I hate bubblers I can find black tubing and little suction cups for them but the stone, or bubble wall things are allways green or something stupid that stick out like a sore thumb. It would be cool if it was black and looked like bubbles where coming out of no where... Secondly Im afraid of them failing and my tank draining because of the neg pressure it will suck all the water out. Im not worried about noise I have carpeted floors in my basement so it doesnt vibrate.
