Im in the process of setting up an 18 gallon fuge on my system so I thought id share the adventure!
Heres the fuge filled with 3"+ .5-1.0mm aragonite, water, salt mix, and a power head to mix it all up! Had to rinse it twice. Got a lot of foam for some reason...
Really dark picture of the filter I took off the main tank to clean up the water a bit (while adding bacteria at the same time)
Here's the main tank it will be hooked up to. Pretty empty looking compared to most... oh well. Patience is a virtue.
I'll be posting more tomorrow including the plumbing and an interesting idea I had about how to drain water into the sump from the display. We'll see if it works, or if the floor gets soaked.
