I have set up a African tank. I have added pictures for your viewing critique as well as suggestions. Having a feeling that nitrates are going to be the main maintenance issue with this setup. I strategically placed the pebble sliders...to create more hiding spots for some of my less aggressive mbunas. The large Holy rock looking decoration is a faux rock. It can be removed fairly easy for vacuuming the substrate. However,,,the REAL rock is going to be an absolute pain. Other than re-decorate the tank...let me share an idea. I have a Fluval 406 canister and a sponge filter already operating. The 406 filters at 383 gph. I was going to add a Fluval 306 and extend the output hose down to within 3 inches of the bottom of the tank and use a directional nozzle directly aimed behind the rock at the right of the tank to hopefully blow out any poop and uneaten food towards the front of the tank so that it can be vacuumed up or directed to the two intakes at the left side of the tank. Am I thinking straight? Is there any problem with putting the output hose that low and close to the bottom? It is a crushed coral substrate..so I wont get a lot of soil being kicked up. I am going after the nitrate causing debris. Thanks in advance!
