Quite possibly, similar amounts of sand came out of the AFC and the air barrel had mild corrosion despite Atomic’s Zirconium plating.
Interesting that Zeagle had an IP spike despite being environmentally sealed and internals protected from debris.
The Zeagle had very massive abuse it seems dragged in the current between coral, rocks, sand, etc. I don't think that "environmental sealing" is meant to deal with this abuse.
