BAD NEWS.
Somehow my 100L is now infected, too! Only explanation I can think of is I got a fighting fish from the same store at the same day and the fish probably all share the water and parasites! (Never going to Pets at Home again!) I've altered the heating settings up so the temperature rises and is at 80f (as it was a bit below) and now I have to do a water change and use the same medicine to treat my smaller tank! SIGH. Gone midnight but I don't want to leave it to the morning.
Somebody worked it out for me the last time because I'm awful at maths and what not, even if it's realtively simple, but it says that 1ML treats 9 litres of water. 100 divided by 9 is 11.11, but because I have to half the dose because I also have a loach in there (that I was planning to move to the bigger tank before the outbreak and now he's infected too!) I have to half it, so that makes it 5 and a half ML's of the medicine, right?
Any help or advice would be greatly appreciated!
