Nitrites -OR- Nitrates?

The guy at aquarium store said 2 most important things to constantly check are ammonia levels and either nitrite or nitrate levels?

Guessing nitrite?!

All three, actually. But while you want Ammonia and NitrIte to be 0 PPM, since they are the most lethal, Nitr8 can be at 25 PPM and your tank will be ok. I think 50 PPM is considered bad for Nitr8? Whatever it is, I do water changes before the test tube fluid goes red.

Ammonia turns to nitrite. If either one gets too high it's time for water changes.

Hello Ang...

If your tank is established and has been running for a few months, you simply need to remove and replace most of the tank water every few days to maintain good water conditions. Tanks up to 30 gallons need a couple of large water changes a week. Larger tanks will do best with at least 50 percent changed weekly. More is always better. If you can commit to this level of water keeping, you won't need to test the water, you'll know the chemistry is always clean and steady for whatever you have living in the tank.

The thing is to find your balance. If you get ammonia/nitrite readings on monday but not on sunday, do water changes on sundays before they go up. If you're lightly stocked you can usually go longer between changes, but every tank is different. It all depends on your stock, filtration, whether it's planted or not and even your water source.

If your tank is established you should never have ammonia or nitrites. And I've never heard of changing most of the water in a tank a couple of times a week

A 50% weekly water change is an appropriate water change schedule for an appropriately stocked tank barring certain fish species such as discus.

Yes, you can get away with not testing your water if you change it frequently. But you are risking an unseen problem in the aquarium. It's best practice to test frequently, but people tend to get lazy at times.
