Are bubbles good or bad for your main tank?
Ive heard lots of yes and no's? What type of aereation is reccomended?

[Reefland]

Well they are kind of required for oxygen in the water. Too many are unsightly and can attach to the slime of some corals which can be irritating to them. It is best to limit the amount in the display for aesthetic reasons mostly.

but ive seen so many tanks without bubbles and theres a thing called bubble catchers and traps for bubbles

...if you keep asking, you'll hear even more "yes and no's"...

I add bubbles for aeration in my refugium and in my protein skimmer... bubbles in the tank aren't pretty, and they can actually cause problems with some critters (especially sponges). ...and I do have a bubble catcher between my refugium and tank to keep the bubbles where I want them.

Yes- bubbles are good, because they lead to needed gas exchange, and No- bubbles in the wrong place wreak havoc.

I've never heard of "bubble catchers" before. What is this?

Many of the higher end hang on the tank skimmers offer a bubble catcher/pre filter box. It catches the output from the skimmer and allows some of the bubbles to be diffused.

My "bubble catcher" is a sponge filter that has to be rinsed out every week or so to keep it from turning into a nitrogen factory.
