I was wondering if I have to do something special because it is a septic tank as they have specific chemicals. Also how about some more from you guys that use a septic tank to dump. Any problems?

Why are you flushing the tank three times? That's a waste of water. Just use plenty of water when you use the toilet, let it get AT LEAST 3/4 full anf then you dump, followed by grey water. Put some water into tank and you are set to go. 7 years fulltiming.

I use Septic Tank Treatment once a year that adds enzymes/bacteria to the system that keeps it 'working' correctly. I haven't had to have the Septic tank pumped since it was put in new in 1985. There is no reason not to use a RV dump on Septic system.

i too have lived in same house{home built in 1955} with septic since 1980 and i have built about One Hundred homes with NoDak style septic systems...they do have to be sucked out and backflushed occasionaly..as the solids after the bacteria eat do build up on the bottom of the tank..if you use your septic prod you can feel the solids ..i have always had a prod with the emty line on it and after 2-3 yrs i measure and see what has built up...and the amount is always dependent on how many live there and what is put down drain...i replaced my feild not the tanks at 1995 as the old field was not properly taken care of....jeff

We had a new septic system installed in 2010. I spent quite a bit of time talking to three of the county soil scientists. They all agreed that there are NO additives that do anything constructive.

They all said to limit the amount of chlorine bleach but it's not necessary to eliminate it totally.

As mentioned here by a couple others, formaldehyde is a no no.

Their number 1 pet peeve and an absolute DO NOT USE item is anti bacterial hand soap!

The blue perfume a lot of people use in their RV should present no problem.

All that being said, I very seldom put anything in my black water tank. Once in a while I use some grey water perfume in the traps.

I'm sure you can guess where I dump, chemicals or not.

BTW, my old septic was still in pretty good shape and hadn't even been pumped for 11 years. Just needed a larger system so we could add on to the house.

The benefits....

Where I'm parked now it's 25 feet from the outlet to the hole in the ground, Now as it happens I have that much 3" stinky but that's a whole lotta hose.

I have been in one spot where it was 45 feet, again I have that much 3" but.. That's ALL So I used the pump and the 50 foot black hose (3/4 inch) and got 'er done.

I had one spot where there was a gray water dump at 74 feet, I do not have that much hose.. thugh I could only dump gray (We tend to need to dump gray more often) so I hooked my 25 foot gray hose and my 50 foot 3/4" Black hose and we made the trip.

I've been in places where the hole in the ground was HIGHER than the outlet on the RV.

Again the pump pumps uphill well

I've been on a site where there was a problem with the sewer and I had to pump next site over.

In short, advantages many.
Wow, I never realized there were so many ill-planned , poorly conceived campgrounds. To the OP, I would try to dump on my way home, if convenient, and skip dumping at the house.
