Riddle me this

I'm sorry to say that 3 weeks is not enough time in quarantine to get rid if ich. 6 weeks is more like it. If you have any other fish in your main tank then ich will stay there. Also, if you decide to do hyposalinity as an ich treatment, 1.018 is not low enough. Aim for 1.011-1.012 next time. Both copper and hypo are not necessary, only one will do IMO.

Copper works amazingly well. I think one week of copper would do it. The problem is you'll still have copper in the main tank. So when the fish goes back it happens again.
The problem we all face.

True that what Billy said. I would just do the hypo and make sure you have a refractometer to get it spot on as the hydrometer isn't good enough. From what I have read, the ich can lay eggs in the rock and be waiting to hatch and jump all over fish. Ive read that a solid three months with no fish could be necessary if the ich gets really bad in order to kill it off in the tank. Even them your only 99% sure it will be gone. Again, these are things I have read.

Different garlic

While I realize your frustrations- I am LMAO.

sometimes I look at my tank and think "why can't you just tell me what your problem is!" then I realize it doesn't matter it's just here to mock me anyways.

Aloha Faith,
While I'm grateful for the humorous references above, there really is an answer to this perplexing situation. Sometimes it's not easy to find, but it's there.
If you don't mind I'd like to ask some questions and to see a pic of the tank.
Let's start with the pic and a description of the tank, along with a brief description of the maintenance routine.
Mahalo,

Okay, that's a good start. I can address three items right here:
I'm sorry if you didn't know this, but vacuuming is not so good for a reef aquarium. This is especially harmful if it's being done every two weeks. I suggest not vacuuming anymore and cut water changes back to 10% monthly. Okay, that's 2 parts of the total solution. We can talk later about a better way to keep the cleanliness you want.
The third item is Garlic. I've counseled people a lot on the use of Garlic Oil. When they follow my advice, it works every time, but not the same way for every tank. What specific Garlic Products have you tried in this refreezing manner?

Please email the pics to me at [email protected]. If its okay with you, I'll post them here.

What are the Alk and Ca of this tank?
Also, can you test for pH at 5-6AM and give us the number?

Hang in there. I'm very confident that we can resolve this situation.

Then Ich started so I pulled her into the qt tank for 3 weeks treating with warmer water, copper and hypo salinity.If that's not the right word let me tell you that I dropped the salinity level down to 1.018 I left her in there for 3 weeks and the ich went away. During that time my bicolor blenny jumped out of the tank and is no longer waiting for her to return to the tank. Now the gramma has been put back in the tank(now all alone) and she has got the ich back. She's scratching on the sandbed and rocks all over again. What do I do?

It is really important that you do your research before you start treating fish.  If you just randomly start doing things it will not work, and you can kill fish.  First of all, 1.018 is not nearly low enough to kill ich (it may kill some, and be less stressful for the fish, and that is why it appeared to go away).  Secondly you 3 weeks is not long enough.  Third, don't do hyposalinity and copper treatment together.

here is how to do hyposalinity treatment correctly (if you choose to go that route).
