Hi Guys,
Thanks for the feedback!
The stuff I've got is Aquamaster Rapid White Spot Remedy. It contains Formaldehyde and Malachite Green. I've halved the dose as recommended for Neons and will repeat treatment after a water change in 3 days. The temp is currently sitting around 27c.
The BN's aren't displaying any white spot at the moment but about 5 or 6 of the neons have it. (lost 3 in 3 days in a tank that has been cycled and is heavily planted, so I'm guessing they were sick when I got them).
Have now setup a quarantine tank and will be using it for all future purchases! I've read that with Ich it's pointless separating fish once they've been added to the community due to the fazes of the life cycle.
Cheers,
Phil
