"The Lab" - Josh and Tiffany's IM Nuvo EXT 200

Update 1-24-24
Tank has continued to chug along. No more random coral deaths, and everything's continued to color up and look better. We're putting a hiatus on adding any more coral to the tank for the next 3-ish months, though, just to be safe.

Food and feeding
Costco was doing a sale on an upright garage freezer last month, so we picked one up. As a compromise with my wife to avoid frozen food proliferating throughout our fridge, I took two drawers in said freezer, and stocked up on frozen food. After asking around, I ended up doing a bulk order from Brine Shrimp Direct given their pretty solid pricing: 77 flat packs (mix of mysis, spirulina mysis/brine, krill, ay caribe, and arctic copepods), 1.2 and 2.4 mm pellets, flake food, and the omnivore gel diet.

For a data point for those wondering how much others feed their tanks: I've been feeding a total of ~15 cubes of food per day, split among three feedings, with one feeding enriched with five drops of Garlic Power and three or four drops of Selcon. I'll also feed a pinch of flake and pellet during the day, since I'm going to be buying an Avast Plank from @Srt4eric soon and am trying to get them used to pellet/flake food for automated feedings to replace one frozen feeding). I'll also give them a sheet of nori every couple days. Given how fat some of my fish are I'm guessing this is leaning towards the heavier side of feeding, but they seem to all be doing well. The coral also gets 40 mL/day of Red Sea AB+ .

Nutrient management
I'm pretty sure adding the bella goby to the tank caused a nutrient spike due to a combination of a prior lack of thorough sand sifting and lots of food on the sand bed. Phosphates got pretty high (0.57 at one point, and 50 ppm nitrate), so I spent the better part of a week slowly dosing lanthanum chloride to bring it down, and continued dosing ~25 mL of homemade NoPox* daily. Phosphates are now around 0.20 and dropping slowly.

I also got a great deal from a friend up here so I swapped out my previous IceCap K2-200 skimmer for a brand new Reef Octopus Regal INT200 protein skimmer. Love it so far: quiet, will be easier to clean, and has a float switch to avoid overflow. I'll be hooking up a recirculating CO2 scrubber at some point to help raise pH, too.

Next steps
Continuing my theme of 'trying to automate as much as possible', my next projects are going to be:
  • Setting up an automatic dry food feeder to replace one feeding per day, and to be able to leave the tank completely alone for several days in emergency situations
  • Setting up two dosing pumps: one four-head doser for Red Sea ABCD dosing, and another two- or three-head doser to automate NoPox dosing and AB+ dosing.

Hi Josh, how many cubes per tray? Are all the tray of different frozen foods same size ie. same number of cubes? Thanks

Feeding 15 cubes per day was great insight, thank you for sharing that. I do not believe there is much information out there on how much folks feed. Still, it was quite a shocker for me :). On another note, seems like you are doing a lot of Red Sea. ABCD/No Pox/AB+. Have you considered or already ried the Captiv8 products for traces or nutrients? I am using several of them, and the cost-benefit is massive. The need for several dosing heads is significantly reduced. Also, I have been using their Remedi8 and Inocul8 nutrient-reduction products (0.5 grams per week), which are super powerful.

Regarding Captiv8, I have not; I'll have to look into them. I was extremely happy with the results I've had with ABCD in the past, though, so it'll take some compelling info to get me to budge. :)

For nutrient-reduction, I'm using a slightly tweaked 'home-made' version from Randy Holmes Farley: 250 mL distilled vinegar, 150 mL vodka, 100 mL RODI. I can't beat the cost and ease of whipping more up in a pinch.

Been a few months since I last updated. Main changes are:

  • Added the BRS Universal CO2 scrubber to the tank to combat relatively low pH. I'm a big fan, and it was super easy to set up.
  • Added a fourth G6 XR30 blue to the tank for better coverage.
Aside from that, not much has changed aside from all the additional coral, so here's a photo dump before I spend the next couple months redoing the control board organization.

Also, dealt with dinos coming back every few days. Couldn't figure out why, then thought to check my UV sterilizer. Make sure you change your sleeves and bulbs.

Yikes!! good find.

Your torches look great! Digging the bare minimum rocks allowing fish swim room.
What's your fish list? Hope the shy ones have caves to hide.

Yeah; I've been running the UV for a year straight without checking, so it's my own fault, haha.

Fish list is:
  • Red Sea desjardini tang
  • Achilles hybrid tang (Achilles x white cheek)
  • Powder blue tang
  • Yellow eye kole tang
  • Bicolor foxface
  • Copper banded butterflyfish
  • Royal gramma
  • Bimaculatus anthias (x5)
  • Banggai cardinal
  • Mandarin pair
  • Watchman goby & pistol shrimp
  • Lawnmower blenny
  • Bella Goby
  • Bluestreak cleaner wrasse
  • Pearly wrasse
There's enough caves for them to hide in, but my wife and I are likely going to add another piece of rockwork to the tank to add additional line-of-sight breaks to minimize any aggression going forward as the fish get bigger.

Re: torches, thank you! Frustratingly, though, we moved the Todd's torch yesterday and it got an accidental haircut by some of the fish. Turns out I should've been more careful about putting it in a location where the long, flowing tentacles flowed right into a cave the fish like to zoom at high speed through...
 
Kinda agree with Eric maybe the PAR levels are a little low for more light heavy SPS? I think @jhuynh had like 10 Radions over his same sized tank lol.
I'm slowly going to raise up the PAR, since I'm currently running these lights at only about 65%. I just don't want to bake my torches just yet.

EDIT: IIRC, he had XR15s (not XR30s) and G5s vs G6. I'd argue that 10x XR15s outpeform 4x XR30s, but the light spread is noticeably better on the G6s so it's probably not *too* bad once I bump it up a bit more after getting more acros.
