tank looks great! are you planning on having just endlers in there? looks perfect for some discus.
ALGAE j/k it will come on its ownhowever I feel like something is missing. Any ideas
That much light, if it's all on for 10hrs/day or more, is gonna grow you some algae real soon! I have a 46G w/ about 2x92W, and I've had to only one run light at a time and break up the daily light cycle just to get my algae under control. I've still got a lot of algae though, and it's because I'm only running DIY CO2 right now, not a pressurized CO2 setup that could pump CO2 into my tank much faster than what I've got going right now.260 watts on a 75 gallon? I would get on the CO2 ASAP. Once algae starts to take hold, you're going to be fighting it for a looooong time. Speaking here from personal experience.
