The window looks out nowhere right now. Its a window well (below grade). Next summer (or the summer after if I'm busy) I'm planning on pulling the ugly metal "well" structure out, digging the back of the well out at a 45 degree angle, and putting in some type of sure or tite lock stones so the well terraces down to the window. That way I can see out and I can add some nice flowers.
Btw I garden in the summer. And no I'm not a pansy... I'm 6'2" 225
As far as the 3 tanks stacked. This is how it works.
# Top tank is the refugium
# Middle tank is the fragment tank
# Bottom tank is a dedicated quarantine tank.
On the side coming off the output of the top tank is a manifold with 3 exits all controllable by ball valves. I can drop water directly back into the sump, into the middle, or into the lower or any combination there of.
The middle tank has an output directly to the sump.
The reason I might want to bypass the middle tank directly to the sump is if when the middle frag tank goes into quarantine and I want to remove it to the main system.
The reason I can dump water to the lower tank is just for ease of fill up when I start a quarantine in it.
The bottom tank has no exit back into the system since there never is an instance when that water should be mixed.
The middle and bottom tanks both have dedicated pumps that pump directly out to the drain. They also have dedicated heaters for when they are removed from the system to keep the water warm. They also have (or will have, the floats just came in) dedicated top offs.
Also the salt mixing tank has a manifold so I can dump fresh saltwater directly into the middle and bottom tanks when they are being quarantined, and of course into the sump for normal operation.
Hope this helps.
