Hello,
I did a 40% water change yesterday because of nitrite levels, and the next readings a few hours later were down to 0. This morning ammonia was close to 0.50 ppm (colour card estimation, using an API test kit) so I did another water change (15% this time) and now it's 0.25 ppm. Should I do another water change or would it increase stress too much? What do you recommend?
I currently have three harlequin rasboras in a 50 litre tank, and nitrite levels have been 0 since yesterday's water change.
Thanks
