Ned,
Got a quick question for you (somewhat of an amateur question). I've currently got a 20G long with 7 n. multifasciatus, 7 orange chela danios, 2 nerite snails and some mts snails. I'm fighting what I would deem a 'slight' ammonia problem with the tank up and running for about 4 months now. I'm running a Penn Plax 500 filter (rated for up to 30G). Weekly 25% water changes, used some of your dirty water to cycle the tank when I originally got the danios, very, very careful about overfeeding etc.
I've been kicking around the idea that perhaps the Penn Plax 500 isn't providing enough filtration and considering upgrading to the 700. Do you think this would help with the problem or am I missing something else obvious?
Thanks,
Steve
