With distilled water, Im not surprised it tested with that PH. Ammonia looks considerably less than test 2.
yes, I think duanes was correct about contamination from when I cleaned the tubes out.
I will recheck test kit #1 again after rinsing with distilled and thoroughly drying.
So chloramine-treated-water treated with stress coat (treats chlorine, chloramine, heavy metals... and I commonly dose a little higher since metal plant weights make me paranoid and who doesn’t like a nice slime coat boost) may still show up in aquarium results?
and trace amounts of ammonia readings are normal for tanks that are established?
180gal is ~1 year old, 65gal 8 months, 75gal 6-7 years, 60gal 8 months, 20gal 3-4 years, 150gal 2-3 years, 5.5 gal shrimp tank 7-9 months, 10gal ghost shrimp/ fry tank 7-9 months. Probably missing a couple, the rest are newer and less than 6 months old.
