Main light is over the tub so is very diffused. The kids in the tank also love to play in the sand, kicking it up. The plants are in pots of clay pellets so no sediment but close lights do grow some algae.Thank you for the pic. I gotta ask, are you having trouble with sediment in the water? Looks brown but it could be the photo. I've seen aquaponics videos on youtube with clear water.
I'm late here but you are clever and funny. When will you reap the fruits ahem of your labor?
