Hey guys....going to be upgrading tank in 5 or 6 months, so am gonna hit the planning now, well before setup and transition time.
In the new setup, I will be running the main display with nothing but drilled external pump streamlike jets, similar to a spa pool.
These holes will be about 4 inches under the overflow level and two each end. They will also have swivel heads or the likes. This will give me my current flow. each one will be around 4000LPH.
I will be running a hospital tank for new intakes that will run with the main system continuously, with 1 piece of large live rock and a cheap skimmer, (Queen, probably). Upon a new entrant into the hospital tank, I will turn the skimmer on and shut of the pumps and shut of the main valve to the display/main sump. Instant Hospital tank whenever I need it for 3 to 4 weeks.
I am actually building a room for an inwall display tank with 1.5 metres operating room behind. this room will be dedicated "THE TANK ROOM!".
The display tank will be around 1.8 metres by 700 by 700.
