Calling all cold water marine enthusiasts!
Nitrates are a concern for every aquarist, however a cold marine tank has a few extra challenges: longer bacterial cultivation times, and NPS livestock with high nutrient demands.
Can the handful of you out there that share this passion give context to a sulfur denitrator in a cold marine tank? Autotrophs tend to be the workhorse according to the cold water lore.
Do you employ any other methods beyond large volume water changes for these hungry and nutrient-demanding biotopes?
Also here’s a couple poor pictures. Feel free to share your own and expand on cold water chemistry however you like!
