Hi everyone, I'm new to the forum so sorry if I have posted in the wrong place.
I (like a few others) bought a 40l aquarium and went back 7 days later to purchase 2 male platy. I was told at the store I could go back in a month and buy some more fish if my parameters were OK. I had my water tested in store and bought 3 more platy.
I THEN learnt about the nitrogen cycle. I rushed to get all my kit to keep monitoring the situation. I did have cloudiness in the first month with my 2 platy and my parameters were all 0 at the LFS
when I bought the other 3.
I have recently after a further month of monitoring upgraded to a larger aquarium (75 litres) for my 5 fish. Prior to this stats were good, sometime elevated ammonia (0.25ppm), 0 nitrite and 0 nitrate. I used my old filter to run alongside my new filter in my new tank and after putting in new substrate (sand) i used old tank water and topped up with treated tap.
MY problem is that since the move (Tuesday) I have been monitoring twice aday with API master kit and had constantly received ammonia (0.25ppm-1.0), 0.25ppm nitrite and 0-10ppm nitrate despite constantly PWC
varying from 25%-50% depending on my parameters.
I am terrified of doing any damage to the fish and because of my parameters prior to the upgrade (they were fine for a few week) I thought my cycle had finished as my filter had been running 2 month.
Why is my water quality like this?!
I am doing the PWC
, using tetra water treatment and did use some nutrafin safe cycle but I am uncertain whether to use this at all after a lot of googling today.
What can I do to keep them down? (other than what I am doing?)
There is around 4 low maitenence plants, sand substate, Stringray 10 (old filter) and EHEIM 2010 (new) running. Any help would be greatly appreciated.
