White spot

[Kate]

A couple of weeks ago I introduced 6 male guppies into my communal tropical tank. 3 died in 24 hours so I got my money back but the other 3 looked fine. About a week later I noticed that 2 of my 4 clown loaches had bad white spot. I treated them straight away with some Interpet no. 6 but apparently that goes off so I went out and bought some WS3, which was recommended. They have now been treated twice with this, 24 hours apart, and are due another treatment tomorrow.

I have lost: clown loaches, cherry barbs, a silver shark, guppies, penguin fish and my last black neon. Still surviving are a shark (with lost of spots), 3 danios and 2 Corydorus (I think). I think the shark will die, but I want to keep the other 5 alive.

I've raised the water temperature to 26 degrees C, and will do a 50% water change tomorrow before treating them. Is there anything else I can do?

Apart from having a quarantine tank for new fish is there anything I can do to prevent this? I've been keeping tropical fish for 5 years and although I have had white spot once before it went very quickly and none of the fish died. I think it had gone too far before I noticed it this time which is why it has got so bad.

Thanks,

Kate

I was talking to someone today about my white spot. He said turn it up to 30c and that will kill the white spot. I've done this now, only been about 5 hours, so will find out over the next couple of days.
He said dont bother with the treatment for white spot, you dont need it. So i will find out soon

Do they look like they have been sprinkled in salt, if so it is whitespot, you can treat whitespot with just salt and turning temp up, but you have some scaless fish so I wouldn't recommend that.
Also what are your test results in ammonia,nitrite,nitrate,and ph, what size is the tank.
