I have a 55 gallon tank. There is also a great deal of rockwork which reduces its water capacity. I use a Penquin 350 filter. To manage aggression i have overstocked my tank.
4- maingano johanni
3- melonchromis johanni
3- electric yellow labs
3- chilumbra zebra
3- chizumulu zebra
2- upsidedown catfish
I do weekly water changes of 50%. Lately i have noticed my sponge gets clogged more often than it used to. When the sponge is clogged, the bio-wheel(s) stops. The filter is recommended to be changed by the manufacturer once/month. I find it needs to be rinsed one week (in tank water) and changed the next, amounting to two weeks of service. I am going to add a second filter (for safety and to ease the load, perhaps extending the life of my media) and would like suggestions as to what would be the best filter for my situation??? I am a fan of the Penquin, it does a great job and the water is very clear. With the amount of fish i have it seems another Penquin of equivelt size would be more than adequate.
