Because most of the microfauna (i.e. your biofilter) cannot thrive/survive at these levels. In a QT, this is not a factor.

I've done that in the past in FOWLR and brood stock tanks. It had the positive side effect that my clownfish larva were so big that they could eat freshly hatched brine shrimp from day 1.
Absolute nonsense! Fish can handle a raise in salinity from 1.016 to 1.025 without any issues.
The thing they can't handle is an abrupt raise from therapeutic hyposaline levels (below 1.010) and even that only if they have been there for a couple of weeks.
Most micro fauna is more adaptable than you may think. Bacteria anyway. And especially the small crustacean critters are quite capable of living and thriving in lower salinities. Many of them come from tidal areas (that's where most of our live rock is collected during low tides) where they encounter at times extreme salinity and temperature swings. In my low salinity tanks I had definitely no shortage of all kind of critters, including Mysis and Amphipods.
The things that don't do well under prolonged low salinity are most corals and coralline algae.

When you originally suggested hyposalinity in combo with TTM I believe you intended for the OP to use a therapeutic 1.009 to help clear the ich.
I maintain that when done properly, TTM stands alone and there is no need to use hypo-salinity SG 1.009 to cure a fish of ich, and is not without some added risk. IMHO for someone as inexperienced as the OP states he is, the added complexity of hyposalinity just is not needed when TTM will work just fine.
Then we agree, raising SG from a therapeutic 1.009 can stress or kill some marine fish.

I agree that TTM on its own should be fine against ich in most cases if executed correctly.
But there are some factors that can cause failure:
1. Though it's rare, Cryptocaryon has demonstrated the ability to encyst on living fish tissue (Burgess 1992). This can in most cases be prevented with full hyposalinity.
2. if using only 2 sets of equipment, sterilization lapses can happen easily (especially when using pumps), especially with inexperienced aquarists. To ensure success one should use 4 sets of equipment. Again hyposalinity would minimize the risk.
Impressive, Most Impressive. Would simplify rearing them a great deal. I would love to see some videos of that.
Unfortunately, when I was breeding clownfish in the 80s and 90s there were no cheap digital cameras like today. I had to use film and got it developed only to find that the pictures didn't come out well. So at some point I gave up on even trying. In the early 2000s I finally got a digital camera but it couldn't take videos.
I had the clownfish breeding so standardized than my mom could do it when I was gone. But the main issue was the grow-out. I simply didn't have large enough tanks. Also it was tough to get money for the fish as most stores wouldn't want to pay more than they paid for wild, but didn't count in the losses or shipping cost involved with those :deadhorse1:
So I shut down in 2002. Had I kept it going another year things may have gone differently as the interest in clownfish exploded after Finding Nemo came out :headwalls:

Not in the traditional sense, no. I don't keep a QT up and running at all times. I use Bio-spira to seed the QT when needed.

Fair enough. However, the animals we keep have evolved to thrive in a fairly narrow salinity range. Because of this, I feel it is in the animals' best interest to replicate their natural environment as closely as possible.
Fish are all transferred to the hospital tank. Day 1 started. Had to remove each and every rock to get every fish. One positive... I've seen our Blenny for the first time of fully seeing him. 6 line wrasse was the hardest to catch, fast booger.
The rock scaping looks a lot better. Fish ate about an hour after being in the hospital tank.

Woke up this am to all fish living. Found the six line wrasse in the middle of what looked like a web that made a complete circle around him. He was laying on his side on the bottom of the 'web'. The web was about the size of a tennis ball. I immediately grabbed my net to scoop him out thinking he was dead.... As soon as the 'web' broke, he swam away like normal..... I had the web in my net and put it down the drain. When it went down the drain it was super thick and jelly like. Odd.
Some species of wrasse go into the sand for protection; others such as a sixline will form a cocoon to protect them from potential predators.
Yea. Bad mom here. I had no idea, I ruined his protection. On a more positive note, he isn't threatened by his tank mates, I think more so by the move of tanks. Tank mates are very calm.
I feel bad for ruining it for him, he doesn't look stressed today though.
Really!! Learn something new each day. Good, well then I didn't destroy his hard work if he does this often. Lol

They do. It also protects them to some degree from parasites.
This "sleeping bag" is typical for wrasses. I'm not sure but wouldn't be surprised if even the ones that dive into the sand build one.

I had a vermiculated leopard wrasse in QT I suppled with a small bowel of sand. One night the sand blew around a bit and I was able to see it did indeed have one of these bubbles.
