I’ve had this tank for about 9 months now. While it’s been very beautiful, my background has been rough. First it was a simple foggy-glass film. Then I removed that to try to add a white one, which only looked worse.
But finally, I was able to afford a dream item - a lightscreen.
And damn, the difference is insane lol. It may show off the algae more, but it really makes the colors pop.
About $80-200. https://thelightground.eu/ https://ultumnaturesystems.com/atmos/

Not my thing, but seems like it would be good for the fishies, as well.
