Ever since putting the fish in the new 250L they Elec Yellows have become VERY shy, they will only really come out when the light goes off and all the fish seem to hide from the light, its quite minimal at the moment as I'm still building the roof for the cabinet and light housing so just has my old light on there at the mo, however they seem to hate it, even when eating, have become really "scatty". I make note that it was the light they've always had on the previous tank
Also the tank takes about 48 hours to get rid of the murkiness now after a water change and the hosing on the intake pipe for the canister filter is quite "soiled" and has a brownish film inside it, I do make note again this tank has only been running for about a week. I understand I have to let this tank cycle but im worried it could be filthy in the canister already and wonder if its why the water stays filthy for so long, is it worth cleaning?
I have been testing the water every 12 hours, and
Nitrates have been steady at around 5ppm,
Nitrites between 0 and 0.25ppm
Ammonia between 0 and 0.25ppm, and the
pH steady at 8.
What the heck is goin on!
