Outer dims and SKU (15661) from Coralife/Fish Tanks Direct. Coralife lists 16 gal nominal with no separate total-system volume (volumeTotalGal null). Stock return is the Coralife S-700 at 185 GPH (700 L/h). Chamber dims are NOT manufacturer-published; derived from the inTank media basket (chamber 2) fitment listed 4-1/8 W x 2-3/16 D x 12-3/4 H, so the ~2.19 in front-to-back depth is the constraining dimension.
