I think that is oddly high for tap water, test might be bad. pH is off the charts too though, test the ph of the tap.
Would chloramine show as ammonia straight from the tap also or only when used with seachem safe?Another nitrate anomaly is when using Seachem safe as your dechlorinator, when chloramine is being used in your tap water as opposed to chlorine. You can get an ammonia reading for that.

I have not experienced it personally because my city water uses chlorine, but I've read over the years where chloramine will show up as ammonia when treated with Seachem prime or safe.Would chloramine show as ammonia straight from the tap also or only when used with seachem safe?
