REDUNDANCIES
Hey All"¦ at this point, while I continue to quarantine and add fish (which I will post some pics of as soon as I can get a decent picture of each) to build up the bio-load in the tank, I'm really just fine tuning some stuff so that this can be as "œset-it-and-forget-it", or, more like "œset-it-and-stop-messing-with-it", as I can get it before I turn the lights on the real fun (and work) begins. The first thing on my list is making sure I have as many redundancies/back-ups as I can, so that when I'm not near the tank, my fish (and eventually corals) will still live on when something fails"¦ so here are the steps I've taken so far (and would be interested to hear what you guys have done):
2 Return Pumps: As I've discussed before, I wanted to have two Return Pumps (one handling the manifold and the other going directly to the DT) so that if one ever goes out, I at least have something pumping water through the sump and into the DT.
Electrical Redundancies:

Battery Backups:
2 X MP40: I have two Ecotech Battery Backups, one each dedicated to each of the two MP40's located at the top of the tank so that gas exchange can still occur for up to 36 hours when the electricity goes out.
1 X Vectra M2: I wanted to add another redundancy to my return pumps and have at least the Vectra pumping water to the DT in times of an electrical outage.
Two Tank-Dedicated 20 AMP Electrical Circuits (and a third non-dedicated 15 AMP circuit): the last thing I want to have happen is that one of the circuits trip, and the whole tank shuts down. So, not only is the tank running on multiple circuits, I've also strategically placed key pieces of equipment on separate circuits.
> 20 AMP Circuit A:
Return Pump 1
Heater 1
Fan
> 20 AMP Circuit B:
Return Pump 2
Heater 2
Chiller
> 15 AMP Shared Circuit C:
Lights
Powerheads
Temperature Redundancies:
> 2 Heaters/Controllers with APEX as Backup Controller: I'm still undecided on how to approach this. I started with the approach of relying on the BRS Heater Controller to control the heat, and only have the APEX Controller act as a back-up (turning the heaters off if the tank goes over a certain temp), but I'm thinking of switching this so that the heaters thermostat is always on if the APEX tells it to be on. Positives/negatives you guys have found with each approach?
> 2 Cooling Elements- Fan and Chiller: I actually have not even had to plumb my Chiller into the system yet despite some really warm days in August and September (although it is just sitting there ready to be plumbed), but I do plan to run both fans and the chiller so that if one fails (or if the heaters fail on), the redundancy will at least buy me time to fix/correct things.
Multiple Sources for Dosing Ca/Alk: I think I've decided on using at least two sources for my Alk/Ca. One, mostly for the pH benefits and added redundancy, will be kalkwasser (dosed separately from my ATO so as to avoid fluctuations). The other will be the Balling Method (using BRS two-part paired with Tropic Marin Part C). I realize this could also increase the risk of overdosing, but I'll be using two elements that increase pH (Kalkwasser and Soda Ash), so my thought is that I'll be notified by my APEX if my pH is higher than normal before a lethal overdose occurs. I'm still figuring this one out, but I have some time before I place all of the supplementation on line.
Multiple Tunable Filtration Components: As I had mentioned before, one of my goals with this build was to make things tunable. Aside from my auto fleece filter roller, everything else that helps remove excess nutrients is tunable (the skimmer, the refugium light, and my auto-WC system). This not only, in theory, will help me better tune my filtration to fit the bio-load of my tank at any given time, but also creates redundancies so that if one piece of equipment fails, the other pieces of equipment can be tuned to pick up the slack.
Sorry for the "œwordy" and "œpicture-less" post, but I hope some of you find this information useful"¦ or at least I can refer back to this for my own use later (if I'm the only one reading this post
).
