I'm treating with both maracyn and maracyn 2 and I'm on the second day. Their info booklets say that they shouldn't kill off the beneficial bacteria in the tank, but my ammonia was showing just below .25 ppm (my tank was previously cycled, though only for a few weeks), nitrites are still showing 0 (I actually never saw any nitrites through my whole cycle, but I did have plants from the beginning), and nitrates are 15ppm. Anyway, the directions for both of these meds say no water changes during the treatment, but it seems counterproductive to be treating fish w/meds while there is detectable ammonia in the tank. Also, I should mention that this is a tank w/corys (aka more sensitive to ammonia, etc). Soooo can I do a water changes and just add more meds back in? And how much would I put back in? I'm pretty sure I need to change the water, but when I was doing a search about this everyone was just saying "no water changes w/maracyn" so I'm feeling confused.:wall: Thanks for any help!
