I love the look, its very clean and pure lookng , what ever you are doing its awsome! Have you lost any fish? again I love that its so clean! some tanks always look a bit hazy, yours sparkles !
I got one chunk of Lava rock in my 40, makes the tank look a wee bit diffrent. Is the sand white sand? also what are you doing to make it look so clean, Have you gone through your diatom phase? How long you run your lights? Are they the reg stock 10G tank lights? and last question what are you using for filtration??
previously i had one 150 gph and one 100 gph hob filters connected to a little home made overflow, along w/ a 120 gph powerhead. but last week i got a penguin 350 filter. in my opinion my old combination worked better but it was extremely noisy
