Ammonia

[Ld123]

My ammonia is very slightly high. 0.25. Why could this be?

 

[jondamon]

Chlorine or chloramines can give an ammonia reading before the BB convert it.

Are you talking about in your tank?
Or from your tap?

When you perform PWC's it can take a few days for the BB to convert the chlorine/chloramine. So you could be getting a reading from that.

Other than that you could have a dead occupant somewhere or you could be over feeding or your filter may not be adequate for your tank.

Yes I am referring to my tank, sorry I didn't make that very clear.

I did a water change on Thurs of this week?

I have looked around for any dead occupants, however I can not find any and no fish seem to be missing?!

I feed every three days so I don't think this would be the issue, also I have a Fluval U2 and a Fluval Mini running in a 90L tank?

 

[jetajockey]

How long has the tank been running?

 

[Ld123]

4 weeks

4 weeks

Is it cycled?

 

[Ld123]

Yes, I used old filter alongside new filter and it cycled fairly quickly

 

[Zevyn]

Did you add any new fish recently?

 

[Ld123]

I have added a plec and 3 silver mollies around a week ago but that is all

 

[jondamon]

The extra bio-load is probably the culprit.

Keep an eye on it but it's more than likely the BB hasn't increased to fully handle the extra waste.


Jon

 

[Ld123]

will this sort itself out?

 

[jondamon]

Yes. The BB should increase to take the extra bio-load. As long as you aren't overstocked already.

I have a 90L with 8 endler livebearers, 3 mollies, 3 platies, 5 male guppies, 6 cardinal tetra, 5 lamp eyes, 3 corys and a clown plec?

I have a 90L with 8 endler livebearers, 3 mollies, 3 platies, 5 male guppies, 6 cardinal tetra, 5 lamp eyes, 3 corys and a clown plec?

And what filtration are you using?

That seems like quite a lot for a 90L.




Jon

 

[Ld123]

a Fluval U2 and a Fluval mini

 

[Ld123]

apart from mollies, platies and plec fish do not exceed 1.5" long

 

[jondamon]

How often do you perform PWC's?


It seems like a lot of fish to me for only 90 litres. This could be the reason your getting ammonia along with the filters.

Someone with more experience of your species should chime in soon.

It could be the bio-load is too great for the filters to handle.

But then it could just be the BB hasn't caught up with the extra bio-load yet.



Jon

 

[Ld123]

the Fluval U2 is supposed to handle a 110L and the mini 45L so hopefully the filters are enough.

 

[jondamon]

the Fluval U2 is supposed to handle a 110L and the mini 45L so hopefully the filters are enough.

The 2 combined should be fine as long as you're not overstocked.

I run a Fluval 206 canister and a U2 on my 200L tank.

But I have a minimal stocked tank.
