I have a
150 liter aquarium
75 liter sump
2 wave makers
heat at 25c
nitrate close to 0
My tank has been set up and running for 6 months now
I keep gettin upto .25ppm Nitrite after about 5 days.
I do a 20% water change when I get this reading. The Nitrite drops back down to 0ppm for a few days then spikes again? has anyone any idea what this could be? because My nitrate never rises?
I only have 2 kg of live rock
I lost a very happy and eating well long nose butterfly today. It seemed perfectly happy last night. But I introduced a blue trigger yesterday not sure if the trigger stressed it to death?? I was told at my LFS
that it wouldnt bother my fish but may peck at corals now and again.
I woke up to find my butterfly laying on its side... I thought it was dead so tapped on the glass and it woke up. I though because of their strange behaviour (like swimming upside down)I thought that it was just resting on its side. But I got home from work this evening and it's well and truely dead!
I have done a 20% water change and removed the body. I know that butterflys are hardish to keep. I'd like to know if it was the water that killed it or was the water permaters changed because of its death?
because I have tested the water this evening and I have a high reading of nitrate and nitrite now
thankyou for taking the time to read
