hello everyone, my tank as shown in the picture is about 4 months old and has just kind of stabilized. I am now thinking making it look more "professional" by adding, removing, changing out plants, hardscape etc. Any suggestions will be most welcome. Its 2 feet long x 1 x 1 and has chihiros A600 series for lighting and pressurized co2 maintained at lime green color on the drop checker. The filter is a very simple waterfall type, hangon filter. There is a wave maker and surface skimmer that start running when the lights go on for 8 hours. The substrate is all ADA and right now I am using the step 2 of ADA, brighty K, and seachem excel on daily basis, and weekly Fe supplement, local made. 25% water changes on weekly basis. There is also a sterilizer on auto mode.
