Ok so I do a seriies of water changes to improve the water quality and then I get a bout if ich. Someone tell me why. I have been in the hobby and understand ich. In the past I have let nature take it's course and the fish were fine.
 
Something you're doing with the water changes may have stressed out your fish and caused an outbreak. Are you sure the salinity/pH/temperature/etc are comparable between the new water and tank water?
 
Replaced 60 gallons on 700 gallon tank. So like 10 percent. Butbyes did stress out the fish. That was 5 days ago
 
Many fish may have ick that is never seen untill he gets stressed. 10% not very much but i think u said multiple changes. How many and how far apart ?
 
10 percent changes for about six weeks.. did like 4 over 6 weeks. on the last one i removed some of the tanks sand bed. i think that did it. other water changes there was no big deal. i am removing the sand and replacing it.. checking my parameters now.. ph usually hangs at around 8.03 and tem around 79 to 80 ..
 
Yea i would say the SB change would do it.

Why are you changing it. Nothing better then older more mature SB. The LR and SB are your best bio filters and tank health indicators. If you have a problem it can be fixed rather then removeing.
 
Woke up to my tangs of over 15 years having it!!!have not had this fit years .. Any new safe products? Do not want to use copper

Tank transfer, copper, or hypo are the only cures I really know of. A couple of the quinine drugs may work, but I've never used them. There are no "reef-safe" cures that work and treatment of all fish must be done in a HT/QT and the DT left fishless for 10 weeks or so.
 
Yep old sand bed. Have large sump in basement that basically handles the filtration. Sand bed in DT is
Or was two inches took out half to replace with tropic Eden.
Question is will the fish survive. They are already scarred.
 
Unless ich was recently introduced, you may hold the record for ich living and multiplying in a tank without being noticed. Have you lost any fish yet? Sure its ich and not velvet? Did the new sand happen to come from an established tank? When the stars are aligned, giving ich a foothold, it can wipe out a tank. if you don't get the fish into a HT soon; you may very well lose them all. Not much info; but based on what you've told us, I don't think ich can be "managed" in the DT any longer. It has to be wiped out.
 
yes.. a fish was introduced about two weeks ago.. so yes I may have messed up.. argg.. my own fault.. ... some fish look like specs of salt .. one has white like hairs.. but my bet is ick...

going to reduce salinity to 1.020 slowly from 1.025. also introducing glaric food and some food soaked in selcon..

will keep you all advised. really dont see getting 15 plus fish into a holding tank..
 
i understand.. but will that not help immunity.. healthy fish to fight off the ick.. can i reduce the DT to 1.009 .. what i will that do to the sand bed, shrimp and micro fauna..

if copper is out, and treatment in a hospital tank is out. then just keep the fish fed and stress free as best as possible and hope for the best.

All the other treatments are snake oil.

They CAN survive the outbreak of ich is healthy. But then again, they can also die.


IME, when I was finished with my stocking, I had an ich outbreak despite qt'ing (without treatment for up to 6 weeks) my fish. Everyone was healthy and eating and they got over the initial episode of ich. So far so good at 8+ months. Would I be happier if I didn't have it in my system? Of course, yes. But really, it doesn't bother me now that my system is stable and few changes are going on. No new fish.

It does remind me that significant stress can cause the ich to resurface and threaten the balance established.

good luck!

I suggest you read the ich sticky. The most commonly observed stage is the trophont, or "feeding" stage and this is an embedded stage either under the skin or in the gills. The fish's immune system is irrelevant since the trophont must drop from the fish in 3-7 days in order to reproduce. So fish do not "fight off" ich. The life cycle of ich has some variance but it goes on and on unless eradicated from the tank. A healthy fish will die more slowly than a weak fish, but unless the fish can develop immunity (empirically observed at about 10%), which protects for about 6 months, many fish simply die. Even those fish with immunity lose that immunity eventually but in the interim are carriers of the parasite.
 
You said you had ich before but you just "let nature run its course". That's where this ich came from. You never got rid of it in the first place. Ich never just goes away on its own. The fish can develop some immunity or resistance but it's still there.

Until you remove those fish to treat them and let your DT go fallow, you will NEVER kill off all the ich.

Hypo in your DT will kill all your inverts and coral.
