Dt hypo treatment

[gregzz4]

Plan sounds good, but transfer your LR too or you'll lose a lot of life in it
Basically, everything except the fish, and you'll lose a lot of life in your sand, but I'd recommend leaving the sand, or replace it. Don't try to transfer it.
Leave the holding tank for the LR, corals et all fallow for 9-11 weeks
Take 3-4 days to drop the DT Sg, 4 weeks of 1.008-1.009 ( no higher ), up to one week to raise back to 1.025 ( or your preferred Sg ) with no more than .003 increases per day
From there, I like to watch the fish for another 3-4 weeks to ensure the MI is gone
Then everything can go back in the DT, given you've done the minimum 9 weeks fallow period for the MI to die off in the holding tank

Of course, you're going to need to feed the corals etc and a filter of some kind on the holding tank, with testing, is a good idea

Lots of testing for NH3, NO2 and NO3 is a good idea, in both tanks

Lastly, it can be difficult to keep Hypo pH close to 8.0. If it's close, leave it
If it drops below 7.8, buffer it with baking soda, and use lots of aeration to help keep it up

I thought the rock would be fine.

Dropping your Sg with the LR in the tank will slow down the nitrifying bacteria, so no big deal, but it will possibly kill a lot of worms, and all starfish, pods etc

[Mike-fish]

I don't have many starfish if any. And getting rid of some bristle worms would actually be a nice plus they've caught on to the trap it seems

[gregzz4]

Have at 'er if you want to Hypo your rock
I did a small piece in the QT and it killed aiptasia
Plus all the big worms came out for capture, and it killed ugly palys, tube worms, feather dusters and the like

Just keep in mind that all the die-off in it will add to any potential ammonia issues, and slow down your DT's recovery after you re-introduce the fishies

Up to you, but I wouldn't hypo my rock
It's like starting over, but without any bacterial filtration
