Earlier this week I gave Concept the go-ahead to build my final upgrade / dream tank. It will be 225gal 5'x3'x2'H euro braced, with external Herbie overflow, Starphire front and sides. I have been really resisting the urge to make it larger and more complicated which is something that I didn't expect.
Once complete I'll build a wood stand and it will go into the wall here. The old 120gal display will then become the new sump.
For now I will continue to use all of the same equipment as before which consists of:
Two 250W LumenMax 3's with 14k Phoenix (until my stash runs out) over the display and one over the sump/frag tank.
Precision Marine Bullet 3 skimmer with Iwaki 70 pump
Reeflo Dart return
Precision Marine 622 Calcium Reactor with effluent chamber
DIY Kalkwasser Reactor
Neptune Apex
Two Tunze 6105 for sump/frag tank flow.
BRS dual media reactor
75gpd Airwaterice RO/DI.
The one exception is I'm adding a Reeflo Hammerhead closed loop with an Oceans Motions 4Way (with 1-1/2" outputs). Currently I use the 4 Way with the Dart as the return and wave maker.
Apart from simply wanting a larger tank this upgrade is to increase the swimming space for the fish, eliminate the centre brace, silence and hide the overflow and increase the sand bed area.
