Can this b used when doing water charges

yes but you have to keep skimmers off for 4 days when using it

My LFS just told me to add a bottle and wait for the ammonia to drop without having fish in cycle, but states adding fish??

Yes add whole bottle wait an hour add couple of small fish but don't over feed them

Is this for saltwater tank

Yes, I used this when I set up my marine tank and it worked great. I was able to add fish and livestock a lot quicker.
