You've been more than enough help already, and no-one else seems to have been affected so far *crosses fingers* thanks! :D
Here's the results from my test kit then :
Nitrate between 25 - 50 mg/l
NItrite 0mg/l
GH About 10 DH (possibly 6, quite hard to tell)
KH 6 DH
pH somewhere between 7.6...
Well I lost that tetra too and from reading up on his symptoms it seems more likely that he had neon tetra disease. From the poor water I assume? I took him out and hospitalised him because I read that it's down to parasites. The eSHa 2000 says it treats the disease but it hasn't impressed me so...
Right, well, I lost everyone in the hospital tank but have still got eight guppies and all nine tetras. The fish all appear to be healthy (except for one tetra who has just developed a patch of fungus on his top fin) but are suffering a fair bit from stress I think, one male in particular. They...
I have a small box filter for the smaller tank.
I really can't believe I've killed 30 fish, I can guarantee I won't be going without test kits again.
Thanks again for all your help
Thank you very much
Could I just trouble you and ask what you think I should do to the water (new or from the tank) to put in the 2 gallon sick fish tank?
Also, it's ten to twelve here and I won't be able to get hold of anything until tomorrow
I'm in the UK and I could not find anything called Maracyn.
I vacuum the gravel once a week and it's only been for one week that I left the water change/vacuum.
What should I use into the new water into the main tank?
The neons all appear to be fine.. a bit concerned by the mass death around them, but fine.
The fish that look healthy, any suggestions what I should do I don't want to leave them to die.
Thank you so much for replying by the way, I'm really in a state here.
Since this I have done two 30% water changes, run a carbon filter to clear the medicine, added a strong dosage of salt, the eSHa 2000 and some melafix. I also checked the ammonia levels and got a reading between 0.25 and 1.5 mg/l, so I've added KIng British Safe Water ammonia neutraliser.
I...
Two more deaths. I don't really want to leave them with just salt in the water all night. Would you recommend giving the carbon a couple of hours and then redosing with the anti-fungus and finrot or waiting until tomorrow and buying something that I can mix with something to treat the other...
Thank you very much for your help.
I've just done a 30% change again, added a carbon filter and half a salt dose. I've had one more death and one on the way. They seem to stop moving their mouths (like they're stuck open) and stick at the surface of the tank, then they just spiral round turn...
Do you think it would be a good idea to put a treatment of aquarium salt into the tank? I want to catch this fungus before it gets really bad and some of the fish aren't looking good.
I don't have any test kits, but I promise you will buy some tomorrow!
The medications are both the same...
Tank size: 20 gallons
Occupants: 30 guppies (most not fully grown, approximately 10 adults), 9 tetras
I have had the tank running for 8 or 9 months and have never had a problem with the fish before. There has been nothing added to the tank for at least three weeks and I have performed a 20%...
