Ammonia with sulfants

I started cycling my second saltwater fish only tank using the fishless method. I purchased clear basic ammonia and made sure it did not have any added dyes or odors. The tank is 180 gal with another 25 gals of water in my sump. I measured out 3 table spoons of the Ammonia to start the first dose.
I later found out the ammonia I used contained sulfants. The bottle does foam when I shake it.
The ammonia is currently at around 0.50 ppm after 2 days. My question is what should I do or do I need to do anything since the ammonia contained sulfants. I have removed about a half of gallon of the water and placed some copipods from my other tank into the ammonia with sulfants water and they have been doing fine for the last 2 days. 180 gal of water contains over 46,000 table spoons and the amount of sulfants is only a small part of the total ammonia solution. I really don't want to have to dump the tank and refill. I found the product safety sheet for the ammonia I used and it only list 1 to 3 % ammonia with no other chemicals listed. Any advise.
 
I wouldn't empty it either. I would wait until cycle is completed and then test the water with a damsel...I'm sure some people would disagree with that though.

I cycled my tanks with ammonia and never bothered worrying if there were sulfants in them or not and have never noticed the loss of fish to some chemical in the water after the cycle. I could have been lucky in the ammonia I picked out so hard to say.

All in all, why empty 189 gallons of water for something that may or may not even be an issue.

Buy that $5 damsel and after a week of it surviving, take it back to the LFS for a credit.

Best of luck!

Thanks I was thinking the same thing. I believe the grain of salt size copepods I placed into the the test water would die quickly if there was something harmful in the water.
