Looking good bud, wish we had a leke place to shop in Klerksdorp ;P
Not good to have a powder blue in a small tank.. That will need to go soon. Other wise your scaping looks nice.
The wavebox may be able to push the water enough for you to notice a wave, with the way the overflow is partially blocked(the comb), it may aid in the wave generation. The other cube i saw didn't have the comb and was working well, he didn't have as much rock as you do though, the amount of rock can be a big factor in how successful the wave is. You'd have to test it I think.
