[fatskater]

1. Water parameters. (ammonia, nitrate, nitrite, PH, temp', Hardness etc)
amonia 4 ph 6.6 nitrate and nitrite 0

2. A full description of the fishes symptoms.
my small peppered corys are dying the one todays head has gone a sort of blood red in colour.

3. How often you do water changes and how much.
been changing every evening about 15 tank including syphoning

4. Any chemicals and treatments you add to the water.
i added amlock and the stuff to get your bacterial filter workin quicker

5. What tank mates are in the tank.
2 small discuss
large pleck
4 red neons
did have three peppered corys (2 week old same as discuss but died)
did have 5 cardinal tetra same time as corys no dead also

6. Tank size.
100l

it seems like my filter(fluval 2) isnt getting rid of ammonia is it knackered or do the foams need replacing etc.

any help im losin my fish

Sounds overstocked to me.

The ammonia levels is way to high, do an immediate water change to bring it down as low as you possibly can.

P.T.

 

[fatskater]

i have been changing the water every night for about 4 nights the the ammonia level isnt going down how long should it take and shouldnt the filter destroy the ammonia. Am i cleaning the foam pads too much.(i rinse them under a tap)

 

[nutter]

yeah, its just overstocked, take the ones you dont want to your fish store, or put them in a diffrent cycled tank

First how long has this tank been set up?

Now do a fifty percent water cahnge, dont forget to add the declorinator to the water you add to the tank. The redness in the cory is likely ammonia poisoning and you need to do the water change to help lower this level. After the first water change then do daily 25% water changes until the tank is stable, Zero Ammonia, Zero Nitrite and a small nitrate reading.

i think that your tank is new and you are going through a cycle with fish in the tank. Either that or you have killed off the bacteria in your tank. the water changes are what will help your fish now, get the ammonia level down below 1 ppm as soon as possible using water changes. keep us posted.

 

[nutter]

OMG NOOOO!!!!

never rinse a fliter spunge under a tap!!! thats your probelm! the chlorine in the tap water will kill all the bacteria which break down the ammonia, thats why its so high! your gunna have to recycle it again

 

[fatskater]

ive had the tank for about 4 yrs ive been water changing 1/5 everynight i do use the chlorine treatment (how would i have killed off the bacteria) also i added amolock which was said to stop the ammonia being dangerous.

 

[Phantom Thief]

You can only wash the filter in tank water. Take the water in a bucket, and rinse the filter media in it. Do not use tap water because the chlorine in it kills the bacteria, as Nutter mentioned.

P.T.

 

[fatskater]

how often normally would you expect to do a water change (how much) oand how often clean the filter etc. As i say ive had a tank for 4 yrs no real probs (the 4" plec is about 3yrs old same tank etc)

 

[nutter]

oops, forgot to tell him what to do instead why am i always doing that lately )

thanks PT for filling that bit in for me B)

 

[nutter]

I do a %25 - %30 water change every week and i wash my filters out in old tank water every 1 or 2 months, depending or the state of them

 

[tstenback]

The most common cause of destroyed bacteria is chlorine. Either forgetting to dechlorinate the tap water before adding to the tank or by rinsing aquarium equipment and filter media under tap water containing chlorine.

Ammo lock also scews your readings when you test for ammonia when using some test kits so be careful of this. Good Luck and keep up with the water changes cause it really does look like your tank will be cycling. Some of your fish are not going to make it as they are very delicate. you should try to relocate them while this is going on especially the discus. HTH

I change 25% water weekly and clean the filter media whenever it gets clogged.

But with your ammonia levels so high, you should change the water everyday.

Errmmm... hate to say this but the fluval 2 is not really meant for a 100l tank. its too big. It will cope if you have a few fish but as you stock it will get gradually worse. Who told you that a fluval 2 would do a 100l tank?!!!! The tit.

The Fluval 2 is meant for up to 90l. You really should have the fluval 3.


I know you have had the tank for quite some time, but you really should get a filter that can manage that amount of water.

^ agrees


Especially with that plec. Plecs produce looooaaaads of waste, you need some strong filtration to cope with it.
