Yeah, I was kinda surprised when I learned it; but it makes sense. According to Dr. Tim, for those interested: nitrifying bacteria are able to replicate and grow faster in hyposalinity because they don't have to spend so much energy keeping all the salt out. Also recommends keeping the bacteria at slightly elevated temperatures (~80 F) because it helps speed their metabolism/grow faster, too.Learn something new everyday
A lot of it learned by trial and error, but I really appreciate it!This thread is a good example of how to research, plan, and be patient that all new hobbyists need to see! Might have to start directing new members here Josh.
Everything Dr. Tim said is definitely correct, only thing to monitor is that your oxygen saturation goes down at higher temperatures and with increased metabolic activity, so likely want to make sure you have good water flow/gas exchange if you're running skimmerless right now.
Curious to see how your pH and alkalinity change during this if you have monitoring going now. Might indicate when you hit your bacterial carrying capacity or if CO2 is building up.
I feel like I read somewhere that you should not use nitrifying bacteria with live sand when starting your tank. Following your build thanks for sharing. Very thoroughGot busy on Saturday, so got it filled some of the way...

And now it's alive (with ammonia + bottle bacteria added, and tank salinity at 1.019*).

While the height of the tank is very slightly awkward for side-viewing, it's perfect for viewing from sitting on the couch, and nice to be able to do top-down viewing without a step stool.

Monitoring the cycle now and, if all goes well, we'll be adding a (small) one spot foxface, a red firefish, a purple firefish, a royal gramma, and a banggai cardinal in a few weeks, as well as a copper banded butterfly when Kenny gets one in.
My goal for the next week is to do cable management and get everything looking tidy under the tank.
*: Was going to do 1.015. However, I added 3 bags of salt, checked the salinity, and went, "Eh, good enough."
EDIT: Also, forgot to put this information earlier, but - in spite of ordering 160 lbs of special grade CaribSea Arag-Alive sand - we only used 120 lbs.
You're welcome! And my assumption re: live and and bacteria was the possibility of more organics/ammonia from dead stuff added to the recommended amount of ammonia added during fishless cycles. I tested the existing ammonia prior to adding the bottled ammonia, and calibrated based on that.I feel like I read somewhere that you should not use nitrifying bacteria with live sand when starting your tank.

I may have to try that... Though I'm laughing imagining the thought of putting a pair of favia on there and giving it compound eyes.Torch for the hair small frags for eyes
You're very welcome. I spent a decade or so as a research scientist; one of my biggest pet peeves was reading another group's research and going, "Okay, I need THIS THING they used, but they didn't give an exact item/part #, so now I have to follow a daisy chain of publications (that, in one case, stretched back into the 1950's)."Looks great! I appreciate that you added the links to the items you purchased and are using for your tank.
Also, quick update: tank has been chugging along for the last few days. Had a couple more pinhole leaks at a few elbows so I shut it down, removed the affected section,, reapplied cement around the joint, and turned the pumps back on 3 hours later. So far so good, and it's been 48 hours without any leaks.
I will, in fact, be drilling the hole once I've got a few more things figured out.Drill the hole!!!!
I like the aquascape and tank. please keep all the updates coming. Im literally taking notes.Tank is still chugging along; it's been about 3 weeks now since I added ammonia + bacteria, tank's been cycled for over a week now (confirmed with 24 hours of processing of ammonia > nitrate), but I have yet to see any diatoms...which is really weird. I'm sure they're coming, but nothing yet.
Excited about this coming Saturday, though! First round of fish are going to be added to the tank courtesy of Kenny @under_water_ninja , and will consist of:
Watchman goby + shrimp
