A few ich questions...

First, answers about the tank...
1. Size of aquarium (# of gallons) 80
2. Is your aquarium setup freshwater or brackish water? freshwater
3. How long the aquarium has been set up? 1 month, but we've had some of the fish about 6 months, the 80 gallon tank is our second tank
4. What fish and how many are in the aquarium (species are important to know) 2 angelfish, 1 pleco (not sure on the specific species, just a common one, I think), 3 neon tetra, 3 red phantom tetra, 5 guppies, 2 zebra danios
5. Are there live plants in the aquarium? no
6. What temperature is the tank water currently? 78
7. What make/model filter are you using? Marineland Penguin Biowheel 350
8. Are you using a CO2 unit? no
9. Does your aquarium receive natural sunlight at any given part of the day? no sunlight directly on the tank
10. When did you perform your last water exchange, and how much water was changed? 20 gallon water change 4 days ago
11. How often do you perform water changes? weekly
12. How often and what foods do you feed your fish? Tetramin tropical flakes twice daily, freeze-dried brine shrimp once per week, 1 algae wafer daily for the pleco
13. What type of lighting are you using and how long is it kept on? hmm, not sure how much info to give, 48" flourescent aquarium reflector, 120 volt, 40 watt, 60 hz, on about 12 hours per day, no timer
14. What specific concerns bring you here at this time? likely ich problem
15. What are your water parameters? Test your pH, ammonia, nitrite and nitrate. ph 7.6+, our tap water is very alkaline, don't have a high range ph kit, ammonia 0ppm, nitrite 0ppm, nitrate 10ppm
16. What test kit are you using and is it liquid or test strips? liquid
17. When was the last time you bought a fish and how did they behave while in the pet store tank? 1 month ago, they acted fine when purchased (don't they all, lol?)

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.

You have chosen medication, so Please follow directions on the bottle. I have used the product you mentioned and in my view It should be used at half dose for Tetras. I have only changed out water if I used the product for more than Three days. Remove all carbon from filters. I would leave temp alone. I usually turn lights off except for feeding and to check on progress or lack thereof. Salt treatment would not be good for Pleco. Hope your fish come around. FYI product PRIME although not recommended can be used at five times the suggested dose.

I have a similar issue in my 20 gallon tank and am using "Nox Ich" which contains Malachite Green. I'm just following the directions on the bottle as I've done in the past. It does say on mine to lower the dose to half for Tetras, scaleless or bottom fish. Since I have a Clown Pleco in my tank with the other fish (guppies mostly), I'm using half dose. I have removed the carbon from the filter and am on my third day of the dosing. It does seem to be working and it has in the past too. After 3 days, I'll change some of the water and check the fish. If I need to after that, I'll repeat the process.

Hope this and 1077's post help! :)

The Ich-cure bottle didn't have very much information on it at all. It said not to raise the temp, and it said 1 drop per gallon.
I used a half dose because of the tetras. I did take the carbon filter out of the tank, and I'm keeping the lights off except to feed the fish.
The angelfish is still eating, he might be perkier today, or it could be my imagination, not sure. Should I dose the tank for a longer period of time because I am using half the recommended dosage for the tank size?
1077, the problem with the Prime was underdosage, not overdose. I saw on the bottle it could be used up to 5 times the amount for nitrite emergencies, but I would be afraid to try that, I think.
Thanks for the advice, I appreciate it very much.

For ich make sure you dose for 7-10 days even if you don' t see spots anymore to make sure you get any parasites still in the gravel or water. Also, make sure you have good aeration as the Malachite Green tends to deplete oxygen levels. Do a water change (with gravel vac) about every 3 days (before you re-dose the medication). Also, watch your ammonia and nitrite levels as the medication may harm your beneficial bacteria.

Good luck!
