Live Rock Bacteria

[Reefaholic]

Hi,

Do live rock's bacteria die after afew years just like DSB? This will eventually result in live rock being dead as all bacteria in the live rock cannot sustain itself without being fed?

Do we need to feed live rocks after certain time?

[clownman]

not sure if i'm right. but think if there are fishes producing the waste, you don't have to feed the LRs.

Personally, I do not feed the rocks/bacteria. Just replace some pieces of the rocks(those that are not nice) with new rocks to re-introduce the bacteria, thereby increasing bio-diversity.

Those bacteria have very simple requirements. They won't die off as long as there is a healthy environment to live in. They will keep propagating, generations after generations for eternity.

DSB don't die, it's just that some of the animals don't reproduce very well in the tank enviroment or that the DSB gets choked up.

Well, live rock's bacteria also need additional food. As was in food cycle. I do believe that bacteria are sometimes like food chain. Just as in DSB, when the bacteria food chain breakdown as bigger animals cannot find smaller animals to feed in, they just die as a result of broken food chain. Sand get choked is because of lots of calcium or kalkwasser being introduced.

Do you know how easy it is to grow bacteria?

Anyway, there is no worries even if they do die off because these bacteria are easily available. They can enter your tank through spores in the air.

So in reality, these bacteria will never die off unless the tank is in a sterile room.

side track a little,

if lets say, 1 piece of LR was totally covered with Coralline algae.....where do the bacteria live....where the bacteria live in the LR through the small holes....

if so, how do you maintain a sandbed with high levels of calcium?

[bwilly]

wat talking u..?

sand bed where got need high calcium...

the residue gonna to harden your sandbed..

so why u only dose the clear liquid after the mixing..

[blueheaven]

oh let me rephrase,

"How do you maintain a sandbed when you have high calcium levels?"

maybe like tis..

how u maintain high calcium level with a (deep) sand bed..?

just dose the white crystal clear water..

good flow.

coralreef,

The bacteria can live on the coralline algae or in the rocks because coralline algae is not plastic wrap and water still gets through.

[magern2]

I think the bacteria will keep growing and multiplying as long as the conditions are good: enough food, not too much algae, enough O2 (for aerobic ones). THey live in tiny holes as well as on the uneven surface area of the live rock.

icic....hope my tank can grow faster coralline algae....

your avantar is rika???
