Angel079 has helped you in the interim, so you're on track with the partial water change.

By the way, nitrates are not a concern unless the reading is very high. Nitrate is the third part of the nitrification cycle (ammonia, then nitrite--both highly toxic, then nitrate). You say one of the "nitrates" was also high; it is the ammnia and nitrite you must keep at "0" once the tank is cycled. With regular (weekly) partial water changes of 30-40% you will keep nitrates down, and if there are plants in the tank all the better; it is only when something biological is seriously out of whack that one sees nitrates above 10-20 in a planted aquarium.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
