Im running 3 powerheads 2 250gph and a 700gph plus I have a hang on that adds some top of the water movement and on top of all that I have a airstone in there! Seem like too much is too much? Ive heard of fish dieing from not enough how bout too much? Haven't had any problems but ya never know. Was thinking of taking the airstone out seems like over kill. oh and this is in a 125 6'.
I will say you're a little under-circulated with 2 250gph heads and a 750, for a 6' 125gal. Do you have additional HOB equipment or a sump and return pump? I would say to ditch the 2 250's, and get 2 more 750's at a minimum.
IMO/IME running a air stone on a SW tank, is purely personal taste. At best, the air stones does increase salt spray/creep, perhaps leading to lower salinity if you correct with only FW top-offs. I don't buy them negatively affecting corals a great ton. Most corals come from tidal flat regions where the daily tide is measured in football fields, and are exposed to the sun/air for hours at a time. Secondly, even without air stones, thousands of people run HOB skimmers that pump lots of microbubbles into their tanks, with no effects. Perhaps a combination of bubbles and poor-circulation that allows the bubbles to collect on rocks/corals/etc, could led to issues.
In some situations, like a tank with puffers that should never ingest air, or if you're keeping sponges (Tree or Ball), then definitely don't run one.
But as the article states, it's virtually impossible to over-saturate the water. You would have to be injecting more then just air to achieve that.
