Fumigating

[Guy]

I'll PM ya. I know a guy who's owned freshwater tanks and is a pro pest control guy. May not need to go fumigation as he has some chemicals only allowed for professionals that is targeted and effective.

Not quite the same, but we had a guy come in and spray some stuff down for ants in the interior of our home.

I just made sure the tank had good circulation and made sure the skimmer was operating as should.

No ill effects.

The majority of spraying was in the crawlspace which happens to be where my sump is!

*sounds like what GUY mentioned. some chemical rather than fumigation.
