40 gal high flow tank

Love seeing your tank photos! Do you take out any of the algae or it just grows perfectly on the driftwood?
 
I do 5 gallon water changes every 2-3 days. I manually remove some with the siphon, but yes, the algae just grows like that on the driftwood
 
Very creative the way the decor just flows from left to right, and I like your interesing stocking.
What filter do you use?
 
That's ok, I had to ask, it sounds very cool & I'd still love it if you can ever get 1. Are the fish still active with the low lighting? I think of them being mostly diurnal but, what do I know without the neat lights? Could be even more interesting!
