I did end up building this tank, but took it down several months later to go to college.
As of 1 month ago (August, 2024) I pulled the tank out of storage, plopped a heater in the back, poured in some water, and fired up the pump. Worked great!
I had my old RODI unit and some filter replacements (how convenient!).
I also had a few pieces of dry aquarium rock.
Just had to buy some sand and salt...
On 9/6/2024, the salinity was at the right level and I dropped half of a raw cocktail shrimp into the tank to kick of the cycling process.
Ammonia peaked after about 3-4 days and fell to zero after a total of 1 week.
Nitrite started to rise early on and persisted at high levels for about 10 days (it's just now under 0.05 ppm).
Nitrate is climbing, as expected.
I'll probably do a 100% water change soon.
What should my next steps be? I want to get some biodiversity (live sand/rock from the fish store?). I also want to get some snails and crabs in there.
