Was it biopellet?

Ouch.. Sorry to hear of your issues. I don't really know anything about brown jelly disease, but if you want to get rid of your bioPellets PM me. I'll take them off your hands.

Xenia need pretty good flow. I would suggest siphoning around the Xenia or turkey basting around the Xenia to dislodge any trapped detritus and revisit your flow now that your tank has filled in compared to 6 months ago.

Maybe this will help you:

I have a wp40 in my tank running at 18V so its plenty of flow. I have already disposed the xenia as soon as I saw the goos coming out. Still no clue what caused it

Yah I also started very slow. Maybe it wasn't the biopellets. But I am being very septical since I like my tank running with the least "external media" so I will stick to that. Less parameters to care about = less headache :P

I can't find a flow chart for that powerhead, and I've never actually seen one before, but using some simple math if the flow is 1130 gph at 12V and 3400 gph at 24V then I assume it must be around 1600 gph at 18V. There is probably a bell curve, but this is my closest guess. If indeed there is only 1600 gph and that is the only powerhead in the tank then there is about 24x turnover. That is reasonable, but certainly not high enough to assume you have enough flow. "Plenty of flow" is not necessarily a number value either - observation of inhabitants is your best bet. Brown Jelly would certainly make me take a look at flow first and foremost. Another thought would be chemical warfare.

A single powerhead also creates a lot of dead spots, and certainly lots of variable flow strength within the system. It's tough to run a reef tank with only one powerhead, personally I would want two in a tank that size to better get more consistent flow throughout.

Don't really know what the flow rate is at 18v but anything above that literally blows away the corals (and the sand at the far end of the tank; even at the back). And I read somewhere that at 18v, it runs at 70% intensity but like you have mentioned, an exponential relationship won't justify that. I will post a video so that you can see and suggest whether I need more flow; I can definitely add another powerhead but that might blow away the corals :P

Any heat spikes?

Nop.

Well I'm sure you of all people will recover from this episode.Even with all the technology and new gadgets It's still hit or miss in the best of tanks.Sometimes there is no answer or cure.Hit the reset button and go back to what worked for you.

Here's a video for you to judge the flow:

Hmm, looks like more than 1600 gph to me. It does look like it is doing quite a good job of creating flow throughout the tank since you have your rocks designed to work with the single powerhead well. Good planning.

My "official" guess then is Xenia Syndrome (my own term lol). Sometimes Xenia melts for no apparent reason, other than the tank has aged. It seems like Xenia prefers new tanks, although this is not always true. The rest of your corals should be ok with a couple waterchanges and some fresh carbon.

Thanks I planned to be less packed with LR and more open space. More fishes

Yah I guess it was just a course of nature where cure has to be deployed instead of pondering over what caused it. I did a 15 gallon wc and another 10 gallon today and have carbon in there. Things looking much better today with SPS having polyps out.
