Tank Crash?

[hwcheong]

Hi,

I saw ppl saying their tank crash. Can anyone advise wht they mean by their Tank Crash?

Thanks

[blueheaven]

a tank crash means that a poison is released in the tank, killing the inhabitants or when there is a drastic change in water parameters and cause massive dieoff. the culprits for these crashes are usually sea apples, anemones, box fish, etc.

Does that mean we should not keep anemone in a reef tank then?

[roidan]

can..but at your own risk just like many stuff out there...

i have 2...

Try ALt-Del-Ctrl...just joking,

When u see the anemone not opening already.. must take precaution already.. try massage it and see if it rot,

If (

open = 0, then

{If (rot = 1), then take out and throw before too late}

Else (leave it)

return(LFs)

)

Obviously u r in computing line.....

[alanseah]

wrong leh.. what lang u using never see if statement use ( rather then {

[chrislwp]

No chitchat ok.. else topic will be close by mod.

Already forgotten the coding, confused with C and Pascal now.

Back to the topic - tank crash. It happened to me once.

Tank after 1 mth later,

1) Added many big fish

2) Added more sand

3) Put marincure for whitespot (overdose)

4) Stop pump, rescape LR

After that, some fish immediately die. Expensive lesson

So it's important to plan probably.

As for anemone, the moment i see it not open for days, before it rot, i will take out the LR and remove the anemone away already.

[alanseah]

well tank will only crash mostly due to poor planning or adding time bomb animal into the tank..

other then that I also know it will be gd that after 2-4 yrs it's best to get starter kit to restart your tank... to prove it from crash.

[chrislwp]

Something to learn. What to do to restart? U mention about starter kit, what to do with it?

The only real problem with a sand bed is the reduction in diversity as the bed ages. This is caused by extinction and replacement problems because the volume of our beds is simply too small for some species to generate self-sustaining populations. This is remedied, by purchasing a detritivore or recharge kit or two every year or so to give a boost to the fauna.

Alan, where does this occur, main tank or sump or both of the same time? Also is there a difference if using a 4 inch dsb and a 6 inch dsb? Would a deeper dsb last longer than a 4 inch dsb?

Newbie alert!

[alanseah]

well from what I know.. a dbs of 4" is enough as 6" is known to crash over time... how true no one know... u may ask those who have encounter be4...

You see a sump DSB is not that very impt play compare to your main tank..

why because of surface area cover and the LS living in your main and of coz the cycling and converting of gas...

Also what type of grade sand u use affect alot as you see.. given the same vol a grade 0 sand have more surface area then grade 1 sand.

FYI, detrivore kits are not available in Singapore. Deeper sand bed would have more anaerobic areas and thus meaning there'll be more denitrification. A deeper sand bed would not last longer that a shallower one.=)

[alanseah]

yup that's the problem u cant get detrivore kits in SG

that's why it's advisable never to buy any sand shifting animal...

but without those sand shifting animal u will have problem of sandbed looking dirty.. sighz..

So those who has DSB in their tank are having a time-bomb?

[alanseah]

well sort of yes for those having 6" DBS but then it's been mention be4 as a time bomb but true or not.. like I say noone know...

[alanseah]

my old 4ft tank been with me for 3 yrs with a 4"++ sandbed never fail on me and working hard and well...

so I never encounter any crash be4....

[strat]

Hmm...I think only time will tell....

So anyone have 6" DSB in their tank?

Mine's abt 4-5" with 6" in my sump.

I am having a time-bomb in my house!!!

Please call the bomb disposal unit ASAP!!!

[alanseah]

lolz...

well I know a few have 6" DBS in their main...

for e.g. rodian 6ft tank..

[ervine]

mine 5-6" approx... should be no problem, there has been word that some have kept a DSB for >5yrs without any problems... so no worries

[alanseah]

well as mention everyone have diff envirnoment for their own tank.. so one gatta dont not apply to others...

just do your way so long not those off the scale think wont be much of a problem...
