A little back story first, that hopefully won't be too confusing. If you don't want to read it, skip down to the space and I'll have my questions! We had an overcrowded 30 gallon tank, bought an 80 gallon tank, put the old tank filter in the 80 gallon, and started moving fish down. We had 5 guppies we moved down first, and I noticed one the guppies had a definite case of ich, the "salt looking specks."
Normally I dose the water with Prime when doing water changes. This time hubby did it and put .8 ml of Prime instead of 8 ml, and while we were out for a few hours, we lost all of our guppies. :( Obviously, I was very upset over this, especially that it was an easily preventable problem. But, because of the guppies' demise, we didn't treat for ich at the time because none of the other fish seemed affected. We did have a few days of poor quality water due to a small cycle, so I had been watching the fish very closely. I lost a neon tetra (old fish), a guppie, and a danio (new fish) during those few days.
One of our angelfish seems to have ich, he some salt looking specks on his fins, he is lethargic, breathing heavily as well. He was still eating as of this morning, however. I went to our little fish store today, to get a treatment for it. They gave me Ich-cure, (malachite green hydrocholoride). I have spent the last couple hours looking at info on the internet, and my brain is so overloaded with info, and no one seems to agree on what works best, what works at all. There is a lot of conflicting info on temperature, salt, water changes, etc. The medication that I got says not to increase temperature. My questions
Do you need to change 20-25% of the water daily when treating with malachite green for ich, to keep the medication from building up in the tank?
Do you need to turn the light off in the aquarium to keep the malachite green from oxidizing? (read that on one site, don't remember which one)
Do you need to use a half dose of malachite green when using it in a tank with tetra species?
I apologize for the novel, I wasn't sure how much information to give, so I guess everyone just gets all of it! Thanks so much for any input.
