Hello; I currently have an ornament at the front of my tank (roughly 12cm long) that allows air bubbles to pass through it and create a nice display. Since I have had this ornament for over a year, it is starting to lose its natural look and I fancied a change. I have recently been looking at Bendable Air Curtains, and Bubble Walls.
Aeration will easily be ok for the tank. the advantages to including a bubbler of any variety (stone, dish, tube) is that it will enhance the exterior section the place oxygen meets water, somewhat increasing the gasoline substitute to assist upload oxygen on your tank water. Plus..they seem incredibly super :)
the bubble curtain is better coz you dont need to stab it i have it for over a year and it works best!
