Question regarding tank crash

[Spidey]

Hi, I am ~1 month plus into this hobby.

I was just wondering when there is a impending tank crash, is there any way you can see it coming and do a water change to minimise the damage?

Eg, you see some livestocks start dying and quickly do a 50% water change, will it save the remaining inhabitants?

Also, usually the corals are the first to go or the fishes?

Thanks....

Regular monitor of water parameters will save. If few fishes die then you have to narrow down the cause. The first thing i will do is check for ammonia and nitrite.

Thanks.

So assuming some fishes die, and I tested positive for ammonia or nitrite, and perform a water change quickly.

This will ensure that it will not turn up to be a total disaster? ie, the remaining livestock can be saved?

[Vinoth]

Depends on how much ammonia is present. You can buy some additives which will consume ammonia and No2. I always have nutrafin cycle with me.

get some polyfilters on hand for shitty situations like that.

throw them in when you sense something is going to happen, or when something has happened.

by changing water too quickly will have worse side effects...

if lets say

anemone die - put lotsa carbon and polyfilter, change 50%

but if fish die, change only 20% and take out dead fish will do...there's lotsa reasons y fishes die, and sometime it has nothing to do with your water..perhaps its not feeding, stress due to shipping...if lets say your tank is already mature and most fishes are alright, but new fish dies, then most prob its just bad luck...

if ur fishes die, do a 10% change will do...if u are kiasu, do 10% everyday for 1 week, it should curb the ammonia spike...never do 50% change unless something drastic happens, like all SPS rtn or anemone or sea cuke get stuck in powerhead...

why nobody mention to dump a double dose of GAC when a tank crash?

activated carbon.

thanks for all the response.

I am especially attracted by the idea of polyfilters.

will go and get one soon.

[terryansimon]

get a few.

they remove NH4/NO2 and impurities, and will not leech them back to the water.

they will even indicate to you to let you know when the filter is exhausted! (=
