I am building a new 10,000 gallon tank to replace my 5K. This tank/pond will be 8 ft deep. Made with concrete and have 3 large windows. What are the best lights to get to try to get light all the way to the bottom?

A lot will depend on your expectations (naturally). I have a 2m deep indoor concrete tank with the front long side made of glass.

I installed clear skylight windows through the tiled roof above the tank spaced very 3m with a secondary 20mm polystyrene sheet inside to diffuse the light and retain heat (tropical fish). This gives the fish tank subdued natural light without algae issues during the daytime.

To artificially light the tank, I have 50 watt waterproof LED floodlights every 2.5m. I dont like seeing the shadow side of fish so I have a row of floodlights along the very front glass wall, tilted towards the middle. And a secondary row of floodlights down the center of tank but my tank is 4m wide. You wont be able to install power points inside the tank legally so your lights will need long power cords. I have 2 light switches per row of floodlight so I can turn on half a row or the full row depending on how bright I want. This was cheaper and more reliable than getting dimmable floodlights (for me). I don't have any plants in the tank but I do run a plant filter outdoors.

I choose cool white (4200 Kelvin temperature) floodlights that create a surface shimmer because I like the dappled ripple shadow effect accross the tank bottom when I turn on water currents

I have a large back wall (concrete) thats blank so during the day when the LED floodlights are off, I can cast from 3 projectors to create a virtual background scene - whatever I choose.

You should design your filtration carefully with a deep tank. The filtration aspects are more difficult than building the tank.

Good to see more large tanks being made.

Thanks for the info. I was planning on having the pumps pull from 3 levels in the tank(7',4',1' deep). As well as a bottom drain. I plan on having them pull from one side of the tank and then return on the other side of the same wall to get a good circular motion. I also plane on having a large bubbler on the far wall to help push the water. I will also have one return as a waterfall into the tank. I have a similar set up now. Do you have any suggestions or different ideas. I basically have a pool filter with a large UV filter. Any thoughts?
