Why? All up lorry!

[flying carpet]

Dear all yesterday night after coming back from work I found out that my skimmer is spoilt due to the valve control, so I decide to fix it in the morning. So I off my pump and head to bed.

Then this morning after my bath went to tank to look at my fishes and to my horor my powder brown,yellow tang, sohal tang and coral beauty are up the lorry. 3 of my clown fish are deterioating.

So what I did was fix the skimmer then took out my dead fishes and wait for my clown fish to recover as well as my yellow goby. But seriously how does turning off the skimmer affect the fishes? It is because of the bubbles it produce within the skimmer itself and the water that came out of it contains air?

By the way my survivors recover after 30 mins as for my corals nothing happen yet but still crossing my fingers.

You mention you off the pump. IS it you just off the skimmer pump or completely off all pump for water circulation? If there is no movement, means oxygen is not generating, still water, of course fish can't survive.

Oops sorry forget to mention. Its the skimmer pump.

[kareen]

what is your setup like? Do you have a sump? If not, it is possible for certain setup without sufficient water circulation.......

hmm just all slience for a min for the 3 dead fishes ............

No sump using canister filter. Mix of both fish and coral setup. 3ft tank using seio wavemaker for circulation. I only off the skimmer pump last night never disturb the filter, chiller and wavemaker switch.

And me once again apologise my other survivors are 3 starfish and 1 fireshirmp.

And my 2 cleaner shrimp also up lorry.

Aiyah everytime I think of it I sigh.

Why Why tell me Why?!

[blueheaven]

Probably due to sudden drop in oxygen levels

[Reefbum]

I have run my tank skimmerless for three months without any problems.The only thing I did was increased my water changes to weekly.Now my skimmer is back on.

[acidjazz]

my beckett is off for 2 days already due to some rescaping and stuff, no problem leh. . i think its other reasons.

i mean u look at lfs, which tank got skimmer? yet their fishes still swimming happily. .

[mantis]

IMHO, unlikely that switching off the skimmer can result in death of the fishes overnite. Did u dose anything before the incident? Overdosing can cause pretty fast mortality rate cos the water chemistry changes too quickly. Or did u add anything else into the tank which may hv contaminated the water and poisoned the fishes.

Anyway, my sympathy for your loses.

[eques]

how old your tank have been?

[flying carpet]

6 mths old. I did a water change a few days before the incident happen. Have bought a new skimmer yesterday. Hope that history won't repeat itself.

I believe your oxygen exchange in your setup is insufficent thats why when you off your skimmer (which is the primary oxygen exchange equipment), your LS up the lorry. The canister filteration may not be enough for oxygen exchange.

Most of us uses a overflow system, so water is well oxygenated during the overflow process.

With less oxygen in water, can it be tested through pH testing?

maybe u would like to check thru a ORP meter

My fishes have paid dearly for my lack of knowledge . Thanx guys for all the info provided. For this mistake I will not repeat again.

[clownman]

Just to add on ...

I used to run a 1.5ft tank with a canister filter ... no sump, no skimmer

I would see the fishes going to the surface for air.

What I did eventually was I drop in an air stone and the fishes went back to normal.

Sorry for your losses ... but we gotta learn from our mistakes

[hammy]

does dropping an airstone increase the oxygen level? of the agitation of water surface increase oxygen level ? or the circulation of water ?

or is it the three but which is the main one ? can someone help to verify ?

[angmoh]

sharing my experience ...

i have a 2ft tank , only with a mini-powerhead for water circulation ... in my tank only have one ocellaris and bicolor blenny ... everything seems alright .. but my ocellaris always swimming on the surface ..

i thought this could be the clown's habit .. hehe but after reading this .. it could be lack of oxygen ..

will adding a skimmer increase the oxygen intake ? if do, i might as well adding one air-driven skimmer ...

[Kelmen]

I believe the air-stone and surface agitation only working the aeration at that part\area, and you do need circulation to "distribute" those "airy" water to other parts\areas.
