Should ammonia be zero?

Apologies if this is in the wrong section.

Should ammonia readings be zero? My reading is less than .25. I have goldfish aquariums, so I have ammonia tests. BTW, don't use the test strips from the pet store. They are as bad as the test strips from the pool store. Use the drop test.

Yes, ammonia should be 0. Increase FC to clear it.

In a perfect world, yes.

But sweat and urine contain urea, which can form ammonia. So anytime you have swimmers in the pool, you're likely goingto have some before the chlorine can neutralize it.
