Help! We have gnats in our black water tank. I also noticed that the seal is broken, Is it possible they have been there all the time? They are getting out now esp when we flush the toilet. Ideas?

I've had that happen twice when leaving a sewer hose hooked up, even with the dump valves closed. Seems that once they get into the hose from the park's plumbing, all they need is the short time the valve is open, to get into the tank.
I've found that they die out after a few generations, couple of months, if I run some bleach into the tank.

Open the toilet and pour some bleach into the tank. Also, get a can of Black Flag Insect Spray and fog the black tank from the toilet end.
(what "seal" is broken?) Any broken seal needs replacing.

I have no experience with that type of bug problem. I do not know what the correct response is.
Flush toilet with fan off.
I'm thinking a serious, generous application of RAID!!!! Let sit for awhile.
See about fixing that seal...

Ummm, they get into the tank through the vent pipe that goes through the roof, not through the campgrounds or your hoses or valves.

Drop a few pieces of dry ice in the tank. The Co2 off gassed will kill em. Of course this works well for me because there's a place down the street that sells ice.

Do a search on the forums for "sewer flies". They do indeed live in the sewer systems, and do move into your hose if left hooked up, and eventually into your tanks and inside your home. I have been in parks where they have flown out of the park connection as soon as I removed the cap to hook up my hose. We have had infestations before. I emptied the tanks and flushed them thoroughly. Then added some laundry detergent and bleach, filled them with water and let sit as long as convenient - several hours or overnight. It is best to fill to the very top (or the bottom of the toilet) if you can. After emptying once more, flush with water and then add a little bleach as you use them instead of regular tank chemicals. After they are totally gone and you are in a different campground, you can resume using regular tank chemicals if you choose. As a help while you have them - I use Black Flag window flytraps sold in a small box at Walmart. These are sticky clear sheets that you apply to the windows and they do trap msny or most of them. I cut them up into about 3 inch pieces instead of using the full sheets since my windows are not regular house size and since I'm cheap.
By the way, I am a little (only a little) surprised at the amount of know-nothing and bad advice posts in response to your plea for help - as always read with caution.
