I have this tank and I'm waiting the arrival of my co2 kit to go high-tech and grow a HC carpet. I wish to upgrade the lighting and have been looking into the Boyu t5 lights you have pictured. Problem is the size you have is slightly too small to fit the tank and the size up is probably way too big (up to 60 cm?)
So the only option I seem to have is to position it the same way you have done on top of the lid. I wondered how this affected the light's ability to reach the bottom/substrate? Did the plastic prevent the "rays" penetrating through the tank all the way and evenly?
I think the 16W (white) or 24w (white + blue) should be enough for a high tech setup to grow an HC carpet?
Anyone experienced please help, cos I'm a noob
