will be following up yr thread, bro. Some 2 cents worth advice, the algae problem which some bros have pointed out. Low cabinet height, please ensure you have clearance space for your equipment maintenance, especially your SM250....., your return pump seems strong and you need to plan your pipe size and sump to support it. going for 2 ft height and low cabinet height, top viewing is good and front viewing may be abit off(personal preference) and for controller, not a must but given a choice, dont just look at purchase price but maintenance support.....some items can buy low but support is expensive. Hope to meet up with you one day to share pointers. All the best.
