Really need advice. Don't know whats been causing problem to my tanks.
I have a 300 gallon tank which has been cycling for more than 2 monthsn until now there's ammonia and nitrite :(
a week ago . after power outtage of 10 hours. all my tanks are now recycling ammonia level high.

Here's a sample tank, This is what happens after a water change

The pre fiter sponge is also clogged

this tank only has an arowana its 4x2x2


my water change procedure is add sodium thio sulfate into my tank, then top up with tap water.
what could be causing this?
will using a 2 stage tap water filter help?
badly need advice.
 
Over dosage of sodium thiosulphate will make water cloudy. It probably wont hurt the fish though.... I cant understand your english about ammonia. If your still cycling then you will have ammonia. There are numerous threads about trying to speed up nitrifying bacteria.Adding another established filter or media or substrate is a good start.

thanks. what i meant was all my tanks now have ammonia. everytime i try to seed my filter. my tanks ph crashes.
Also my tank now stinks :(
 
Your bb can start to die off at 10 hours. When that is pumped into the tank it is toxic. I would do a large water change and add some bio-spira.

Its not rocket science so if you are still unsure what to do then your not searching very well. Look up "new tank syndrome" if your really stuck. I would stop feeding the fish for next 6 weeks and add a temporary large established filter to your tank. If your unable to borrow another established filter then beg-buy-borrow some established (dirty is good) gravel from your aquarium store or friends and temporarily add this as filter media into your existing filter.

If I were you, I would throw out your pH meter and put up with any temporary smell. Do some serious reading if you honestly have no idea what is happening. Understanding the nitrogen cycle (and bio-filtration) is one of the basic building blocks of fish keeping.
 
thanks for the help everybody. really appreciate it, I sold all my arowanas. :( guess i'm too tired after years of keeping fish. this is the first time i experienced this kind of problem,
 
I think the ammonia is still high because with a reasonably large tank such as yours it will take longer to cycle then lets say a 50-100g

good luck! also a power outage could have killed all the beneficial bacteria if your filter wasn't running , but i bet it didn't kill all of it off

good luck :)
 
thanks everybody:) btw my 300 gal tank has completed cycling,
but my other tanks are still cycling, I'm waiting for bacteria to be stable in my sump before getting some media to seed my other tanks :D

IMO: Going 10 hours without power and/or circulation I would consider that water as stagnet and polluted. The filtration will have to go through another cycle and I would highly recommend a 100% water change.

agreed, do a 100% change add ph buffer and bio-spira. this will maintain ph levels while you re-cycle
