Fish Crazy
Ok, i will try and explain this again. I have had my tank (108ltr) set up for 4 weeks. After 1 week i put in five hardy fish (i didnt know about fishless cycling at thispoint), 2 zebra danios and 3 platys. After 2 days, the female platy had fry. Then, after 4 days one of the zebra danios died, then the female platy died and then the other zebra danio died. So, i feared the cycle may stall so i got another 3 platys. The water parameters at this point were ammonia 0.25 - 0.50, nitrite 0.25, nitrate 10 - 20 and ph 7.8 - 8. So i was back up to five fish again, and started doing daily water changes of 25-30%. I got some donored matured filter media and gravel 2 days ago andput them straight in. One of the new platys has also died now( she did have ragged fins when we got her though). The ammonia level is 1.0 and has been for 3 days now, nitrite is reading 0 and nitrate is reading 10. I have tested my tap water for ammonia and its negative. The four remaining fish seem to be happy, they are being fed once a day and when i carry out a water change i vac the gravel. Is this how it should be going or is there something not right. I have used another nitrite test as i had a spare one and that also reads negative. Surely i should have some reading for nitrite now. Advice please!!!!GRJ
