Setup looks killer though. Love the dimensions.  |
It looks low because the tank is so frakking shallow LOL.
That return outlet is only an 3/4 to 1 inch below the water line. I measured :-). So not that much water is going to siphon back. The sump is only half full (possibly even less) during normal operations so ya there is lots of room for water in the sump. I always design my systems this way. Pretty much the exact same deal as my 150g. I actually use this to my advantage when doing water changes. I turn off the return and let all the water drain and siphon into the sump that can and will. This fills up the sump tank. I then just pump out all the water from
the sump tank and refill to the previous line with NSW. Turn pump back on. Done :-)
