Cucumbers do not dig they just sift the top layer so there no problems. the SS star should only be in larger systems. I have had one for about 2.5 years in my 125 and he is still doing fine. It was another LFS
buy, there fine you can have 2 or 3 in a 125 8O 8O Now I know better..
I like the look of a shallow SB over the DSB
, I have around 3" in my reef and 4" in my fowlr
and all is fine. I do not like the look of the DSB
when it starts getting the denitrification areas going, black dark green IMO
looks like crap. JMO
