just checked both my tanks and its good news, ammonia 0, nitrite 0, ph about 7.3, im ready to go.
my 30 gal has been set up for about two weeks and my 90 gal has been going for 4 days!
when i got my 90 gal going the 30 was just starting to show nitrite, i had been doing alot of reading on the subject and went and got a friends used filter.
i cut it in half and put a piece in each tanks filter system.
the next day i had a nitrite spike in the 30, that lasted two days. i did 25% pwc on it those days.
the 90 never did spike, ammonia or nitrite, it raised slightly but nothing i would call a spike.
now for the hard part, adding fish slowly. i want them both full now!
i know i want some neon tetras in the 90, what are some small colorfull tankmates that would do well?
