Thank you! I have spent a lot of time planning and saving for this tank so the neatness was the result. My 75 was more or less thrown together. I have the tank filled with fresh RO water now with the pumps running. The MP40's are still on the 75g and will be the last thing thats moved over once I sell that tank. So far, so good. Only 2 leaks, one at the return pump inlet and one on an elbow from the drain (Its right over the sump so no worrisome leaks around bulkhealds (thank god). Now I am trying to locate the "noise" and dampen it. The siphon break in my return outlets is one noise that I will try to eliminate as the water under pressure is shooting out of it making a splash effect in the overflow box. Another noise is the drain into the fuge, I believe if I add a "T" fitting in here with a downspout below the water level, that will reduce that and finally, the drain section in the sump; there is so much water falling that its crashing over the first baffle making another splashing noise. As for the skimmer and return pump, its relatively quiet. Just a small hum that is not noticeable when doors are closed. As for the update since the last one:
I installed the ATO reservoir, made a bracket held on by a magnet for a float switch (its the little black square in the photo, a little DIY to say the least. I took some acrylic that was in the garage, added some heat and bent it to a bracket shape. Drilled a hole, mounted the float switch, and drilled 2 additional holes that hold the ATO lines secure in the reservoir. This switch will alert me via email through the apex when the reservoir is low on water)
added an 800watt coralvue heater controlled by apex
mounted the aquamedic dosing pump for the kalk stirrer and a toms aqualifter for fresh water top off only
installed 2 more float switches in the sump with brackets (purchased these)
made another bracket for the ATO return, kalk return, and calc reactor return lines to keep them secure in the sump (same process, heated acrylic to shape and drilled holes)
added some plastic straps to hold the PVC pipe in place to prevent movement and sagging
soldered the float switches to extra wire then hooked up to breakout box (used heat shrink to insulate the spice connections and also to color code which chord went to which switch; red, white, blue
mounted the apex and ran wiring neatly in the sump / cabinets; used black flex conduit to hide the ugly wires and keep it neat while securing everything with outdoor electrical mounts (little white brackets attached to the stand: notice them fastened to wires and tubing)
Once I fix the leaks, I will then program the apex and switches, add the salt, mount the display controller (still deciding where to), throw in live sand and base rock with a little live rock from the 75 to start a cycle. I also plan to nuke alot of my old liverock as it has some unwanted hitchhikers and will add it to the tank over time as it cycles. While the tank is cycling, I will start building my DIY LED fixtures. Here is a few photos and a quick video I took earlier this morning to give you a general idea.
