Marine Ich help please

[dsaundry]

I am having a hell of a time with Marine Ich in my tank right now. I have had little bouts over the past 10 years but so long as the fish were eating and moving the always seemed to be fine in a few weeks. This latest bout has been going on for a number of weeks and the casualty list is growing. Other than copper treatments is there anything that you have found that will stop this thing cold. I havent seemed to find any sure fire things on the forums or the internet. Any suggestions. I don't have a qt tank anymore and according to a number of forums that isnt really an answer anyhow. Copper is out as the inverts and corals probably wouldnt make it. Water perameters are good. Any help or suggestions would be greatly appreciated.

Is this a FOWLR?

If it is a FOWLR you can do hyposalinity in it for 6 weeks. Keep Prime and a salicylate ammonia test kit on hand in case some of the nitrifying bacteria die (causing ammonia spike). Most of the nitrifying bacteria should survive hyposalinity, but some people do experience significant troubles.

EDIT: Nevermind I see corals in there now. How many corals? Can you remove them for 6 weeks to a temporary tank?

Hi Darryl,

A UV sterilizer will help keep it in check.

Make sure there are no temperature fluctuations either.

Cheers,
Tim

Not a folr system unfortunately, I have a uv sterilizer but its only a 36w, I think I may have to go to a 72w from what I have been reading. The temp fluctuates between 78 and 82 depending on time of day. I cant keep the fluctuation any closer even with fans right now, maybe I will invest in a chiller.

Bump your heater up to 81 or 82 then. No point in letting it fall to 78 at night.

How big is your tank? Which return pump are you using? How is your UV plumbed (to the return?)?

Tank is a 140g, uv is plumbed into sump. Pump is a mag12. eventually going to an eheim1262.
