Air stones and/or powerheads needed for my 125G??

[Tpepe321]

Set up is below:
125g freshwater tank
No live plants
2 Seachem Tidal 110s
1 hydor koralia 425 powerhead in there now which I'm thinking is underpowered for this tank.
I had a 10-12" air stone but the adapter snapped off

Should I replace the air stone and/or add/change the powerhead? Are the HOBs enough?

You said "needed". No.

A bubble wand will create surface agitation and current which helps oxygenate the water. It also creates upward current which helps regulate temperature. Both of which helps improve conditions.

But... what you have is certainly "good enough" to create suitable conditions.

So the question becomes... Will the benefits of the bubble wand improve conditions enough to matter... There are countless details that will impact that, there's no way for us to guess (accurately).

Monitor the tank. If fish are breathing heavy, they my need more oxygenated water. If the temperature is inconsistent, you may need more current. If waste pockets in undesirable areas, my may need adifferent current pattern.

What your tank needs or would benefit from depend heavily on what is in the tank. Whats the plan for fish, inverts, plants, etc?

It also depends on what type species of fish you keep.
If you keep rheophillic species like I do. (Geophagines, Cribroheros, Darienheros, Thorichthys, some Rheophillic Plecos)

A strong current could be more important that just a simple air stone for their well being
My fish come from riffles and rapids, so beside a strong flow from the sump, I add 2 powerheads to the 180 gal to keep watrer moving, and well oxygenated.

The rivers the species I keep are quite rapid, with lots of movement.

The rapids like waters above, are where I catch Plecos like these, and you can see they love the movement.

Of course if you keep slack water species like severums, angels, or anabantids such as most bettas an airstone would suffice

duanes I plan on keeping 3-6 frontosa and 1 or 2 Delhezi bichirs for now

Then you'll probably be fine with air stones.
