Is bubbles good?

[Chichan]

Hi

I have a JBJ 24 nanotank. When the pump is turned on, the outlet of the water flow introduces lots of bubbles

into the tank.The outlet is just slightly above the water surface.

I read somewhere that mircorbubbles may not be good to fishes in a reef tank as they

might get into their gills.

Does it mean that the outlet should be below the surface of the water to minimize bubbles?

Thought that more bubbles is good as it introduce oxygen to the tank.

Any advices appreciated.

Thanks

Having a lot of bubbles going into the tank alters pH which is surely not ideal, apart from the other things you mentioned

Yes increase the water level beyond the outlet.. but if it still does happen, maybe a picture can help us to identify the problem

Thanks Mossrope, I increase my water level above the outlet but still allow some agitation on the water surface.

The bubbles are now gone. Hopefully,without the bubbles, it can still introduce enough dissolved oxygen.

As long as your water is not stagnant and there are surface agitation.. there is no problem...

Your water level is so low? You didn't use the surface skimmer attachment? I suggest you get one, it gets rid of the surface film of scum, and creates an overflow effect. Easier to maintain the water level like this too.

This is new to me... If bubbles are not ideal, then those with super massive skimmers how? The whole point of a protein skimmer is to create bubbles to interact with the water right?

Not being sarcastic, I am really curious

I also din know that having microbubble will cause the pH to drop... Unless you are pumping C02 bubbles in your tank?

Ph wont drop unless the gas that is in contact with ur water is either an acidic or basic gas. CO2, being acidic will change ur Ph. oxygen will not.
