These add A TON of surface area for bacteria / pods. Super beneficial imo.I currently have 2 Brightwell ceramic plates in mine but not sure they really add much. Sponges love to grow on them but I don't care for sponges in my tanks. They become a nuisance and choke out corals.
I don't think adding rubble is worth it unless you specifically want an area for detritus to collect for pods.
It’s been awhile and my info may be dated: Fluidized sand beds will convert ammonia to nitrates effectively but to convert nitrate to nitrogen you need a dark anaerobic (no light, low O2, and low flow) area with high surface area.This is something I'm strongly considering, can you elaborate on ? Sand used, and the reactors?
I guess I should have been more specific, as I understand the theory of the fluidized sandbed, many are in solid colored (dark) containers.It’s been awhile and my info may be dated: Fluidized sand beds will convert ammonia to nitrates effectively but to convert nitrate to nitrogen you need a dark anaerobic (no light, low O2, and low flow) area with high surface area.
That's what they say but real world results haven't shown me any benefits. They are much more a place for detrirtus to become trapped and then flow through them is restricted or blocked. I could pull mine and likely not see a single issue from it.These add A TON of surface area for bacteria / pods. Super beneficial imo.
Collects more detritus too though, but the fluidized sandbed would counter that issue.Sand is way more surface area and 2 inches deep is plenty oxygenated. One volume of sand is thousands to hundreds of thousands times more surface area than one volume of rock.
it's just a pump and a pipe into a container of sand, no detritus here...This is something I'm strongly considering, can you elaborate on ? Sand used, and the reactors?
