18 hours is fine. I would stock if I were you.Mine's still doing that tooAmmonia disappears in 12 hours but nitrIte takes 18 ish
And same as you it has been like this for 10 days - I have timed it everyday and there is no change.
My potential stock option included 12 danios so I think I will get them this weekend - but I'm not going to add anything else until I'm sure its ok
Its odd that mine and yours are doing this - no-one else seems to have had this problem. Wonder if its anything to do with our water quality? Are you UK?
ETA - just read your profile - your only about 60 miles from me - wonder if that is a coincidence???
Im looking at 6 danio's and 1 RTBS and 2 Pear Gourami's a few Khuli Loaches and 2 Pleco (Smaller ones)
I guess the 6 danio's and RTBS and maybe 2 Gourami's should be a good start. let it settle and get the rest.....
PS.... Sarahp Yeah it is a bit of a freak similarity. water is harder our way. more chalk. Who provides your water???
