Exclamation return pump returning air with water...

My return pump sometimes blows air with the water that is being brought back to the tank, is this bad? should I make i adjust it to make it less powerful of a return, and stop the air bubbles. Please let me know what I should do? Or if its normal, or if its bad for the tank, fish, live rock and so on?

Thank You

Personally, I wouldn't think too much about it, I doubt it will cause any substantial harm to any marine life, but this is an interesting question and I'll be curious to here what other post

Micro bubbles. You can put baffles (bubble trap) into the tank to minimize the bubbles coming into the tank. it's put right before the return.

More then anything it's annoying, but there's a theory that if it hits the areas where there's not much flow and a lot of detritus, it could cause an ammonia spike. It doesn't really happen, but it could depending on your tank (many things can come into play for this).

I wouldn't decrease the flow. Just get some baffles and create a bubble trap. Google sump bubble trap and you can find out what I'm talking about.

I have tried to find baffles and could not find anything good, or even a good pic of what it looks like and what not

can you see air getting sucked into the pump? usually the evaporation will make a pump suck air because the water evaporates from the return pump area. increase the water in the return pump section if you can.
