has just about finished cycling - nitrite is at "0" according to my testkit (seachem one) - 0 is apparently very light pink. And, the colour of the test is lighter than the lightest colour on the test strip.
But, I know that TRUE 0 is totally white (as is my main tank).
Ammonia is at 0 and has been for a week or so.
It's been at this stage for ages (about 2 weeks) after both ammonia and nitrite peaking and falling.
What should I do - would you do a 25% waterchange and call it a day?
