Thanks sketch! It has been a very long journey. I have everything hooked up now, however since I mounted my project box, it is now in close proximity to the capacitance sensor, and I am getting the ghost readings again
So now I will have to move the sensor board again... Oh well. In better news, the tank is being put back together. Since I intend to have such a pronounced slope, I am going to use egg crate under the substrate to help with erosion. Work has begun on that part, and I intend to flood the tank sometime this week
Underneath the tank. Still a little messy, but I'll do some cable management down there soon.
Closeup of the chemical injection port. I drilled a 3/16" hole in a PVC cap and pulled some air line tubing through. There is a check valve just outside of it. I have two lines running into the top cap, as I didn't really have room for another PVC "T" fitting. I will run micros into the single port, and macros into the T fitting to keep them from mixing and precipitating. I also was able to calibrate the pumps today.
