So here's my next question about the WP25s ...
I have successfully kept nanoCubes over the years. I am now venturing into a big tank. I don't like the looks of cables hanging around - I go to serious lengths to hide all cables for Entertainment Centers, computers, etc. (I have rebuilt cabinets to include areas to hide cables - I HATE seeing cables!!)
How do you mount your WP25s? I was leaning towards mounting on the back wall of the tank - that way the cable in the tank would blend in with the black back wall ... but I don't think the back wall is an ideal location for these pumps. I haven't tried yet ... I just haven't seen many circ pumps mounted on back walls, they always tend to be mounted on the side walls.
