I am in the process of re-setting up my system. The tank is 2mx1mx1m (480UK galls) 250-300 kilo of LR-minimum stock at the moment.
The sump is a 'marine pond' set into the floor, size is 1.5mx1mx600mm deep (120UK galls), it is stocked with red manroves, has a 6" DSB and about 40k of LR, when finished it will hold a cryptic zone.

The mangroves have been pruned to bush them out.
