whats on my leos?

  • We are currently upgrading MFK. thanks! -neo
Personally I think a 60% water change is too much, especially followed buy another.

I fill my tank through carbon but I always add dechlorinator at the same time, just in case.

I would like to see the water parameters before the 60% water change to ascertain why it needs to be so large.

If a 25% change would do the job then I would work with that.
 
The kh, gh, and ph in the tank -are almost at the exact same levels as in the tap water, at the time i do water changes (ph may rise about 0,2 some times). The only real fluctuant factor in water chemistry (that i measure), is the nitrate level.
(But about the chlorine... hm)

The reason i do 60% water changes is mainly because the nitrate level will rise to 25-50 mg/l in 3-4 days.
-So yes, the tank is slightly overstocked... and maby i culd/should change my wc routine (-smaller changes more often)...
At least, i have decided to move out the 5 tank mates, first thing tomorrow.

Of course it is not bound to have anything to do whith the water chemistry... Culd it have something to do with the physiological stress, while changing water...? -Well then, why haven't this happened before.........?

Anyway, this is what happened today; One hour after i did the 60% water change, the number of spots dubbled(!) Then, 5-6 hour after that, she suddently had lesser spots than before that water change...

:WTF:
 
Good to see you know your stuff about water.

I wonder if it could be Chlorine, Cloramine or Phosphate in the water? Or is the temperature swinging a lot with the changes?

I Nitragon will remove Nitrate from the water and it also removes phosphate.

I would try a phospahte test and keep an eye on the water temps and make sure you use a dechlorinator that also removes chloramine.. Also maybe try 2 smaller changes.
 
The temperature can some times drop one or two degrees after a water change (keep them in 27 celsius)...
I am almost constantly guarding the temp while filling up the aquarium. So at least i know that they haven`t been exposed to any larger temperature swings lately...

----
I will try to get hold of a Phosphate test kit. And i am considering changing the wc routine... -like you say, maby do 2 smaller changes in stead of those bigger ones...

Anyway, my plan right now is to try one thing at the time... eliminate possible causes one by one, and see what happens... Think that is the best way to do it.

Thanks you for advise.
 
its deff not phosphates, we have very high phosphates here in detroit.
 
I did a 40-50% water change earlier today. And same story as yesterday - it got worse right away, then got better again...
... right now, about 4 hours later, it is actually almost gone. Seems like it is going to disappear...

No3 level is now down to about 5 mg/l...
 
If we can rule out phosphates and the temp is not moving much and it does happen after water changes then I would have to suspect the Chlorine or Chloramine????

What else could it be?

Could there be a lot of copper in the pipework supplying the water perhaps but then that would stay in the water unless you have something removing it.

I think you are going to have to test just about everything in the tap as well as the tank.
 
Its all gone now. I talked to the breeder, and he have also experienced this, but never lost any rays....
 
test the hell out of the tank now and write it down, then if it comes back compare every parameter.

I read an article in pfk talking about voltage leak in to a tank and to test for it you had to run a multimeter with black lead in the earth and red in the tank (if you plan to do this pm me and I will scan you the article) before, just to be safe!
