And don't rush the process or you will be back to square one.
From experience, I will testify what Beth is saying, you have to do the process exactly with no shortcuts or you will not only spend work, time, money and energy for possibly nothing to only have the ich come back.
Hearing on the various threads on this forum that fish only can live in hypo mode for quite a while, I chose to take the most common opinion of how long the fish must be in hypo AFTER the very last spot of ich is gone, thats when you start the clock. The clock does not count while you are working on lowering salt levels and it does not count when you are raising salt level. Clock starts only after you have the fish at the hypo salinity level AND the very last visible spot is gone. Then you begin the count.
I went for 6 weeks in that mode - fish were fine. I had one issue though, I used Maracyne once while in hypo mode and it made my fish very very ill one night, almost lost him. I do not recomend medications at full stregnth in hypo, if any at all. At least that was my experience. The only reason why I tried some Maracyn while in hypo is because I read that secondary infections are fairly common from ich condition. I thought he had a cloudy eye or a little cloudy and thought I was doing a good thing, it was just all too much for his system.
Keep the water temp and salinity stable, lights on a scheduled timer, let them eat when they are hungry to rebuild their energy, nutrition and imune system and don't make any other changes during that time of hypo. No meds, no new fish, no decoration changes. Keep it simple.
I found that I think my fish did very well with very small baby steps to brint his salt level back up. People are right on the money that raising the salt back up is more stressfull for the fish that lowering the salt. I saw the difference. For that reason, I never raised his salt level more than SG number at a time, (ie.., like 1.015 to 1.016). Wait a day or two, then raise it again. Sometimes because life is busy with other things or sometimes I think the fish didn't have a particularly good day, I even skipped 2 full days before I made any changes.
Good luck to you and don't listen to pet stores when they tell you that you can eliminate ich with 2 weeks of hypo. Wrong. Ich has a 28 days lfe cycle. If you do the match for retail business of a pet store, the hyposalinity lowers over a week, and by the second week the cycsts fall off. For the lfs, that is the magic time when they can start pushing the fish back out the door to new homes. For the loving owners that own the fish, that is only the beginning. The cycsts fall off the fish to the substrate. People think the ich is gone. However, the cysts that fell (and I know I am not using the correct word or names for the ich at the varous stages
), that is when ich re-occurs. The free floating cysts look again for a host of a fish passing by, jumps on the fish and viola, ich again. People think they got ich again, when in reality, they never fully eliminated the cycle.
It is clear to me, hypo takes time and patience, lots of tiny changes done carefully. And I will never introduce anything in my main display tank again without 3 weeks of QT. Maybe even longer. I don't ever want to go through that again, if I can avoid it.
But I learned from the best - saltwaterfish.com. Beth was a huge help with hypo - thanks Beth. My puffer is alive today, because of your help.
