Tank crashed

[Shinguuji]

my tank just crashed a few days ago, the day the website went down, i think i topped up water using untreated tap water and the chlorine killed all the bacteria in the filter, i moved by percula clown out already(that's my only fish) quite sad to see my tank crash a week after it has cycled...hiaz....nitrite is very high now...shkd cycle fin.(again) in a week or two

[jazzben81]

I DONT think tt chlorine will kill the bacteria.

i dont use RO/DI filter unit but just tap water treated with anti chlorine.

however,

how long did u actually cycle ur tank?

maybe u should give more on the parameters of ur tank.

[junyong84]

i think u shld restart everythin again..

cycled the water for a mth or so...

[Shinguuji]

nitrite and ammonia is over the readability scale, no point giving, prob. arnd 20+? whe i cycled, both of these were zero for a week till it crashed, maybe something dropped into the filter leh?

strange thing is that lots of algae growing in my tank liao, indication of lots of nitate, even after change water still got nitrate, but i didn't overstock leh, put one mandrin(late remove liao, given awy.) and a perc. shouldn't have been overstocking...very weird, i also dunno why like this....somemore got the barnacle thingy growing frm my life rock, plus crabs etc. my life rock seems very alive....all types of things growing on it....a lot of pink red and purple algae growing on it too, cover nearly the whole rock liao...weird...i also thought those crab will die bcos of the nitrite, but still alive, also dunno why...

crashed?? maybe more detail on wat u meant by it..?

corals all die by left one clown?

or clown the only survivor?

if your nitrite is veri high, then something is wrong with your water.

tap water won't affect nitrite. its your ammonia spike (maybe from

one dying stuff) that produces bypass pdt of nitrite later onz.

[dradttg]

Agreed with bwilly. I have been added untreated tap water to my tank without any problem.

[Shinguuji]

crashed as in the nitrites and ammonia blew out of proportions, suddenly acclerating from zero to 20 in two days, nothing died

[hongqixian]

Another ancient thread but:

the pesky crabs are hardy enough to survive being in the rock and out of water for a while, through crashes, high nitrates etc. they need to be picked off manually. real nuisances.

[tigershark]

i did'nt treat the tap water also, just pour in the pre mixed Kalk/tap water into my dripper.... for the pass 1 yr ++, no problem at all....

[hamannbmw]

my tank crash also today .........harlequin n mandarin dead.... , maybe becos the stupud mandarin is suck into the power head....releasing toxic...

Anyway does mandarin release toxic .....

[hoppinghippos]

shinguu: everyday I top up 3L of water straight from the tap, but everything ok. you sure its the tap water or maybe something died releasing toxins and hence also causing spike in ammonia and nitrite?

u shd leave ur water over night...

i top my water for 2 months.. nothing happened..

did u leave ur water over night ?

sometime i leave it for 2 days... before topping in.. everything is fine...

i also once top in water without leaving it over night.. same as urs.. tank crash.. all die... and i leave it running for 1 weeks before getting anyfish.. till now 3 months no fish die yet.. all running perfect...

I use water straight from the tap. Never used any anti-chlorine tap...10 plus years of fishkeeping and it has never given me problems. Last time freshwater can change up to 80% with tap water without dechlorinating nothing die also.

Think it depends on which part of SG you are in.....

Leaving water overnight makes a different of the chlorine contained in the water?

Pls advise.

[hoppinghippos]

leaving water overnite allows the chlorine in the water to escape. I used to do that too, when I was keeping planted FW tank, but wah lau very leh cheh, in the end just connect hose from tap in toilet to tank and top up this way, nothing die either.
