D&D (Deltec) are sole UK improrters of what is basically a rebadged JBL Cube.
Ive swapped out the supplied pump with a maxijet 1200, stock into chamber 1 outlfow back into tank, also purigen and rowaphos and a filter floss particle filter in chamber 1. Temp and ph sensors in here as well.
Chamber 2 has live rock rubble and chaeto lit by white leds on a reverse cycle. Chamber 3 heater, MJ1200, float for autotop up
Ive put a tunze mini pump into main tank behind rockwork structure giving a total circulation of 33xhr (net capacity after diplacement 68 litres)
12.5 kg of matured live rock mix of Fiji and Indonesian (about 2kg in rear sump)
Std 72w of PC lighting, automated moonlights and I ve added a cold cathode tube purley aesthetic and have 3 stage dimming
