Infected water in main tank what todo?

[Pazzoman]

Hey everybody,

My cousin called me and told me some fish that his gf brought him had ick. And she put it on the tank despite that thier was a little hole in the bag...so basically some water from the bag got into the main tank. He is very worried now about his corals and fish. What should be taken?

I told him do a water change as well as purchase kick ick which i heard was safe...also told him to raise temp a bit

Ick is always in the water. Its when your fish get stressed that they become succeptable to it. How big is the tank that the fish are in? I would just turn the heat up a degree or two. Not too much though, you dont want to cause unneeded stress. Do NOT add any chemicals

Raise temp. in tank to 88*. Ich or rather the parasite is not always in the water column. Leave the temp. up for 3 wks. By the way raise temp. Slowly.

will the high temp endanger the corals or other inhabitants of the tank? I am dealing with ick right now and have shrimps and snails in the tank as well. thanks in advance.

DO NOT TURN YOUR WATER TEMP TO 88, IT WILL KILL ALL OF YOUR CORALS! Sorry for the all caps but reef tanks not the same as fish tanks. Above 84 corals will definitely bleach, any higher and they are dead for sure. If he is super concerned get a uv sterilzer and run it constantly. Ich parasite has a free swimming stage where it will be vulnerable to uv or micromechanical filtration like a diatom filter. This will take it out of the water. Some people will say it is always in the water, not true, but it is likely that any time he brings in a new fish, coral, piece of live rock, etc he could bring it in. Only way to totally prevent is to quarantine fish in hyposaline environment for 4 weeks, and to buy all corals from fish free systems. Not really possible for most people, but it is the only way.

+1 the only way the temp increase works is with fresh water tanks... because the high temp kills ich while in it's free swimming stage.

In freshwater ich has 3 stages in sw it has 4 - it is not the same parasite. Higher temps speed up the life cycle of the adult ich thus shortening it's life span. Anything that changes stability in reefs is bad news including temps. Adding salt to FW fluxuates the salinity killing off the free swimming babies the same is done in sw using hypo salinity but your lowering it not raising it. Changing salinity in SW kills of B+B and inverts so we do this in a quarantine tank. The "extra" stage of marine ich is the hard part. Ich larva rests protected in the sandbed and deep within the rocks for 4 to 6 weeks waiting for a host Freshwater ich does not thus we remove the fish from the system for 8-9 weeks the entire lifespan of several generations of ich to insure against reinfection. The only reef safe treatment I know of is herbtana a natural non med treatment but it isn't with out issues as the treatment requires removal of chemical apps and skimming which raises nitrates and po4.

You sure must be a kind and gentle soul! Fist time ever, in my whole life, i hear about the ich parasite as 'the babies '.....
