Hello all. Just joined the community this morning and was really happy to find this community. I have recently restarted my fascination with the aquarium hobby after a ten year hiatus trying to afford children. Lol. I now have the excuse of a 12 year old son who loves fish, spent countless hours and local zoo checking out there aquariums to get back in. I have messed with all types of aquariums but finally decided to go the african cichlid way. Through some discussions with LFS and a whole heck of a lot of reading I have decided to get away from the carbon and go different route. Explain my setup. 56 gallon column with 3 mbuna and 11 peacocks. Adding two to three more in next month. Got a great deal on the setup so all my fish are juves (no bigger than 2 inches) and getting the pieces together to move them to 75 gallon shortly. Running sponges in the back corners powered with power heads and a c-360 marineland canister filter. There has been some recent growing pains with a problem with high nitrates and found out there was too much food going in. Got this under control. Just wanted the opinion of u all between the two listed above. I really like the fact chemi-pure has been around long time. Used in reef tank in the past. Appreciate any comments.
