New here, tank is 4 years old. Remodeled my basement 10 months ago and burnt out one of the hydra 32s. After that I just turned the remaining light off and the only thing I did with the tank was add to the ATO every 3rd day. 3 weeks ago I decided I really want to make this tank the way I had thought 4 years ago. I removed and cleaned all of the sand, changed the aquascape with the existing rock work, did a 20 gallon water change, and turned the single light back on. 2 weeks ago I cleaned the sump, 20 gallon water change, bought 2 clowns and a bullet goby. Today I received the new hydra 32 and put black window tint on the back glass. Haha now you are all caught up on the last 4 years of this build.
