Welcome!
South Shields here
Im pretty jelly of the separate fuge, mines in the sump. If it were me i might have a mangrove in there (always wanted one)
Not sure if im allowed to mention names but i use charterhouse aquatics and kraken corals for all my equipment needs (both uk) next day delivery. They also sell any fittings you may need and are able to suggest the right parts for the job.
Ohh yeah
The fuge will help with cycling, it will act as a food source for copepods and other beneficial organisms.
