bubbles???

[Ldmii23]

i know i used to see alot in freshwater tanks an undergravel airrator that let bubbles rise from the bed to the top of the water... i havent seen it in saltwater tanks that ive noticed... its something ive thought about doing but trying to figure a way without burrying it the sand(which isnt my question).. my question is if there are any potential risks to the system to do this what are they

thanks in advance

i havent noticed anything i have been running one in my sump.. i used a red slime treatment 6 months ago and ran it to increase the air. just never took it out.

It just adds oxygen. Shouldn't be any issues long term

Salt creep will be a nightmare.And can damage lights above it with creep on electrical contacts.Otherwise no problem doing it.
