At pH 7, are nitrates and nitrites equal to each other in regards to fish safety? Or does one still override the other at that ph?

I think that nitrites are alot more lethal then nitrates at any level!

True

Nitrite levels must always be kept as close to zero as possible!

 

[Fishman]

If your tank is cycled properly than your nitrites will always be at zero but you will always have nitrates to deal with!

Yes: nitrates are the final product of the tank's cycle (and therefore will always be present in your tank in increasing amounts). They are removed by doing water changes.

water changes.

KEY, as long as you keep up with the minimum schelduled changes you should be fine

i thought nitrates were not dangerous to fish?

 

[piranha45]

25% water changes a week is Ideal right?

 

[Judazzz]

25% per week is fine! Opinions on what is ideal will differ fromperson to person, though...

And nitrates are not nearly as harmful as ammonia or nitrites, but high quantities are still very dangerous to fish.
