Just tested the tap water which hascome up at 50 or 110 even boyfirned has said it's difficult to match up, lol.
On the booklet of Nitrat it goes in levels of 5, 10, 20, 50, 110 so I guess it is bit high.
the nitrit level goes up 0.1, 0.3, 0.8, 1.6, 3.3 this level when tested earlier today was at 0.1
the amonia book shows levels at 0, 0.6, 1.2, 2.4, 4.9, 7.3 so is 0.6 quite dangerous??
sorry for all the questions.
Noticed tonight that the gills (inside) on my two sharks look a little on the red side and their tails look slight pink however just changed lights today so it could be that. Should I be worrying???
