Running hypo in the display tank

[kkelloww]

I have a 155 gal bowfront about 5 months old. I added these fish over that time period without quarantining:
1 powder blue
1 powder brown
2 royal grammas
1 firefish
1 purple firefish
1 true perc clown
1 black and white clown
1 carpenters flasher wrasse
1 mandarin
1 foxface
1 coral beauty
1 flame angel

The 2 tangs are showing signs of ich. At the end of each day, it seems that they are ridding themselves of it, but each morning it returns in full force The blue has it the worst. They are still strong, active, and eating, but I fear it will gradually get worse and spread to the other fish. I do not have a QT/hospital tank. I do not think I could catch all of these fish without totally disassembling the tank. Then, I would have to buy a fairly large tank to use as a QT tank and I don't have the filtration for it.

Would it be possible to remove the coral (all LPS) and as many inverts as I can find and do hypo in the display tank. I have somewhere that I can keep the coral/inverts? Do it for 8 weeks. Would that destroy the biological filter in the rocks and sand?

OR you could remove corals, inverts and use Crypto Pro (Quinine Sulfate)...figure two 5 day treatments for Marine Ich.

Worked for me very well in my DT:

It will not get the biological filter if you are careful, if the tank is mature, and if you maintain good water quality throughout. You'll get some dieoff that will test the system re ammonia, but have an ammonia badge, test, watch it, don't overfeed, and use all your skills and you should get through it.

Are any of the inverts rsistant to hypo? I have many snails, hermits, 2 urchins, a brittle star, a peppermint shrimp, and an emerald crab. Some of them I don't think I'll be able to find and I don't want to kill them. What about the quinine in the DT. I read that you can't keep therapeutic levels when dosed in the presense of live rock/sand.

Read my post above w/link....I used Quinine Sulfate in my DT...no affect on nitrifying bacteria. It will kill algae, some inverts, and corals must be removed.
