After the central overflow, the water runs down to my sump.
Key Objectives of my sump;
1. Mechanical Filter (Filter Sock, Live Rocks, Bio Homes, Carbon/PO4 remover)
1.1. Chiller Pump Area (!/5 HP chiller)
2. ATI BM 250 Skimmer (To maintain water level for constant skimming.)
3. Holding area / Aclimisation area for new Fishes or Frags
4. Refuge Area for growing Chaeto / Bamboos /pods, Further reducing nitrates and other nutrients (4xT5 2ft Hopar Lights for providing artifical sunlights)
5. Return Reservior, housed a Eheim 1262
6. Freshwater Reservior for Auto-TOPup to Return Resevior (Hence, keeping constant Return Reservior level)
Note:
Currently not planning to use FR or other equipments, as budget is damn low, and to opt for 2nd hand equipment to save the earth.
Heres the illustration..
