A bit early starting the build thread and this will be a slow build, but I'll document the whole process beginning to end this way.
I just picked up a 125 gallon marineland display that's now (after having to lift it in with my wife scary process) in my living room. Directly below it is a room that my wife has graciously allowed me to take as a fish room.
My plans are a 125 mixed reef with alot of alot of softies and LPS only a few acros up top. I'm still debating lighting likely the NICEREW gen 2 lights 3x 150 watt.
Below it is why this will be a slow build. I'm using 4 55 gallon HDPE barrels for a sump I'm planning on using uniseals to run them in unison at about 16" water height. Above them will be a 8'x4' (8 inch tall) ebb and flow table with LED grow lights above it. I will be trying out different tropical Halophytes to see what species grow well at reef salinity. The plan is a slow rise in water on an independent low wattage pump that pulls from the barrels. Then slowly drains using a bell valve and standpipes. I'm new to plumbing so this will be interesting to say the least, a steep learning curb.
The basement fish room to the display water level will be about 14' so I'm planning on a large AC pump plumbed from one of the barrels.
The fish room is 9'x8' so a tight squeeze but it'll work. I'm wrapping the walls in white poly and putting in a bathroom fan. This will take a lot of tweaking to get right so it'll be awhile but thanks to anyone who read all this!
