Hi all,
I’m new to the hobby and am looking for advice on keeping the ammonia down in my cichlid tank. I’ve got 15 fish in a 55 gallon tank. All mbuna with the exception of two orange splotched cichlids, a blood red parrot and a common placo. They all get along peacefully. I was going for the idea that they’re less aggressive when it’s stocked up. So far so good....except that ammonia level. I do weekly water changes (50%), use a marine land 375 penguin with the rotating bio wheels, stocked the media basket in the filter with ceramic media and stuffed the baskets of the filter with foam. The tank has been stocked with fish for at least 6-8 weeks. I do have Amazon swords in there. I used a piece of foam from another tank that was already colonized with good bacteria in the filter for a week before I added the fish.
I’m going to add a sponge filter. Between the moving bed filter and the sponge filter, which one does a better job of bringing the ammonia down?? How much longer should I wait before I expect the see a healthier, more cycled tank? Any advice would be valuable.
