Nitrite Level.....how Big A Water Change Should I Do Now?

[hollyp0p]

My nitrite has gone up to 0.25 this week, my tank is being treated with myaxzin and pimafix at the moment so it might be due to the meds....my ammonia is 0 and my nitrate is 5ppm.

I'm due a water change tonight anyway, should I just do my normal 25% or should I do a 50%??

I would do a 10% water change every day untill levels drop to normal levels. I personally think adding chemicals can cause problems later.

...already done 25%, but I will monitor it and make smaller ones if/when necessary
