To Bubble, Or Not To Bubble?

In my six gallon Eclipse set-up I recently added a bubble wand. It makes plenty of noise and seems to freak the fish out a bit. Is this a necessary or advisable thing to have in such a small tank? Also, I am currently cycling a 30 gallon tank (long) with a Penguin 280 filter, should I be thinking of buying a bubbler for this tank (it seems like the spray bar set up on the bio wheel aerates the tank water pretty nicely).

chris..a bubble wand and depending how big it is? a bit much for you little 6 gal as you said it seems to be freakin the fish out and you are right your 280 is all you need for your 30 gal..bubble wands look cool but unless you really need that extra aireation they aren't needed..

Chris, I wanted to get a little aeration in my 5.5 gal tank, but like you found the huge surge of bubbles from even the smallest air pump available disrupted the entire tank and freaked out the fish by creating an enormous current. The solution I came up with has worked great. I bought a two-way gang valve which is mounted on a plastic hanger so it hangs from the side of the aquarium (gang valves in various sizes are available at any good-sized pet store--mine came from Petsmart). I ran the line from the air pump to the inlet of the gang valve, and ran a line from one of the two valves to the airstone in my tank, with this valve fully open. The remaining valve serves as a bleeder valve. When the air pump is running, I can adjust this second valve to bleed off excess air and thus regulate how much air goes to the airstone. The result is that I have a gentle flow of bubbles for aeration that is just right for my little tank. If the hiss from the bleeder valve bothers you, you can attach another piece of tubing to it and direct the bleed air back behind the aquarium or under the stand or whatever your tank sits on. I hope my explanation makes sense. If it doesn't, let me know and I'll see if I can do better.

Bubblers and bubblewands in most tanks are not necessary, and are mostly for aesthetics. They add some oxygen to the tank, but with a good filter that agitates the surface somewhat, you will have good oxygen saturation anyway in the water, even if you have a closed hood on it by diffusion through the water surface alone (after all, the hood is not *airtight*, I should hope). In a smaller tank, say a 2 gallon with a betta, I recommend against it, as some fish are disturbed by too much water motion.

Thanks, as usual, for all the good advice. I decided to pull the bubbler out. Much more peaceful. Question: I have an Oto in this six gallon tank and I read that they have a greater need for oxygenated water. Is this true and how can those be met with a sic gallon tank?
