Hmm.. tigersax,
I take it you are talking about a different Colleen? Please for the fifteenhundreth time don't share your opinion and then give me credit for it. If you have something to say, say it, yourself.
I THINK..
Garlic is great. Its delicious in pasta. As a treatment? Can't hurt. Garlic has been used for hundreds of years in livestock as a treatment for parasites. Problem is, one guy will swear by it, and the next guy will swear it doesn't work.
Cleaner shrimps have a job to do in the ocean. Ich isn't really first choice on the menu for them either, they can't Cure your system, only manage it. Same with just really really good care. If your tank is in perfect health you may never see an ich outbreak until you stress your fish. You are managing the problem, but not solving it. As Jen said, they can help, but I really think these guys need to be left where they are needed.
Those white spots? Those are the little guys that cause Ich. They appear and disappear as they live, die, and reproduce. On the fish you only see part of the life cycle. They are doing other fun things in your substrate and water too.
To get rid of ick:
Take every fish out of your display tank. I would have to look up how long to leave it empty, but without fish, the parasite will eventually die out. We are talking weeks here. It's a hassle, but it's not like you can treat a whole reef system with hypo or copper, so there are really not other options to CURE - most people decide just to manage and hope they don't have outbreaks in the future.
If you run all fish through QT it will never be in your tanks at all. Can a coral that's in a tank with ICK introduce it to your system? YEP! Look at where you are buying from and if you have a doubt, run those through QT too. ( Side note, never had a problem with ANYTHING from Rob's store =). The parasite can't host/reproduce in the coral, but it can catch a ride from one tank to the next.
I like treating with hypo. I run about 1.009 specific gravity for a week plus. Take a few hours to drop to this level. Be sure to syphon out the bottom of your tank while doing this to help speed along the process. Don't use substate/live rock. It's a good place for parasites to live. This is fish only - it will kill inverts. Hypo messes with the reproductive cycle of the parasites. Some people specualte that hypo may actually make it easier for the fish to osmoregulate. My fish have spent longer than a week in hypo just because I get busy and don't want to adjust the s.g. back up until I have time to observe the fish. They manage.
Copper works. Follow instructions on bottle. Use a test kit to accurately measure copper levels. Use only in a QT tank (Bare bottom, no live rock, etc.. ) Any substrate will absorb the copper, as J-Hook pointed out, and can leach it back out into the system later ( bye bye inverts). Don't run carbon in your filters with copper. It removes the copper. Copper is harsher beacuse it supresses the immune system of the fish. You are killing the parasite, but leave the fish with almost no ability to fight it off itself.
When I'm about to go out of town and need the problem cleared up quickly, I've used copper. When I'm going to be around for a bit and can watch I use hypo. When I've gotten confused during a water change I've used both (at the same time).
For Ick I wouldn't bother with taking out and dipping in little buckets. There are also treamets with moving fish between tanks etc, but I really don't like to stress sick fish any more than necessary.
If you don't want to buy one, please borrow a QT tank from someone - it can save you a lot of time, money, and heatache later on.
If you see dots in the morning and fewer in the evening, it probably is Ich. If your fish just have a white spot now and then it could just be crud from the water, and spot of sand, whatever. I hope Bottles just likes to play in the dirt!
I lost a total of six fish last time I moved. I was in a hurry and added a tang to my tank that had not gone though QT. She/he/it was fine until the move and then the stress caused everything to explode. I ended up with crazy water chemistry (doubly so with the skimmerless, and no mechanical filter), ich, brook, and just stress from being moved. Everything tank related was still packed with the exception of the main tank, but I think two of the fish would have pulled through it they hadn't decided to try to fly... Live and learn right? With the excepetion of the great move die-off I've never lost a fish. Quarantining and treating new fish before they go into the display tank really works.
Again this is just what has worked for me. There are other effective treatments, and a whole lot of ones that aren't.
