Hi. I purchased a 72 gallon bowfront aquarium that was previously used for saltwater. I am going to be using it for Malawi mbuna cichlids most likely P. saulosi and maybe one other species. It came with a wet/dry filter with bio balls. I have never used this type of filtration. I have only used Eheim canister filters or HOB filters in the past. The tank is drilled for the wet/dry so I guess I am going to have to use that. Is it okay to use this type of filtration for cichlids? Should I use any additional type of filtration or will the wet/dry alone be fine? If for some reason I decide not to use the wet/dry how do I seal the tank? I am currently giving the tank a good cleaning as it was not cleaned before I purchased it and has some dried salt. Any input is welcome. Thanks.
