I'm looking into the new Waterbox DX 100.3 Reef tank but am having a hard time swallowing the $1100 increase in price over the regular reef 100.3 tank . I see the sump is upgraded to now include an ATO reservoir but still no option for a filter roller. I am new to this hobby and looking to purchase my first tank ever and want to do it right. Any advice appreciated on whether this purchase is worth the premium.
