Originally had a medium chocolate Tang, medium sailfin, two green chromis, two clowns, neon dottyback, coral beauty, small hippo tang

Your nitrates are especially low for this stock? Is it a 150 gallon plus? Anything to munch up nitrates with heavy feed? Has to be?

They’ve been consistently low. Around what I’ve listed. Nitrate had been around 2 at its highest.

That's likley the issue. As the tank matures the fight will get easier!

It’s a 180. They get half a sheet of nori for breakfast and A chunk of reef frenzy a little larger than a quarter.

There is also general brown algae I think growing. I’m assuming algae as it does not have air bubbles and is not stringy like Dino. Plus snails like eating it but not tangs

You are underfeeding IMO

Things that kill quickly would be toxins (dino die off possible or sensitivity to added medications), oxygen deprivation (from added medication or die off) and certain diseases like velvet can kill rapidly (but if quarantined properly, less likely). So one question to what I think most likely happened, how much aeration does protein skimming really provide? We are keeping the aeration bubbles in a chamber flowing upwards with minimum microbubbles leaving the chamber. Most skimmers are in a sump not directly attached to the display and still minimum turn over of water and microbubbles. I would venture to guess that more oxygen exchange occurs in the display with powerheads breaking the surface than a skimmer could ever hope to achieve. Anybody measure dissolved oxygen in a tank DISPLAY with the skimmer turned on or off for comparison? So sorry for your loss, it really sucks, but just some thoughts on what may have happened.

No this is what I needed. I’m a hard thinker and yes. I agree. A lot
I do have to WAVs aimed at the surface but they shift to night time mode at 2300. Then the skimmer shut off at 0000. Maybe it was a combination of everything all at once. Either way I don’t think I’m going to dose it again but for a last resort.

I was wondering that as well. I always bounce back and forth between I’m over feeding them or not enough. I mean now that half of them are dead it makes the amount easier to increase..

I would be hard pressed to dose anything in my display. I use about 1 to 2 cups of carbon in a reactor, but only change it out sporadically if I remember, that is the only thing I've dosed other than alkalinity/Calcium supplement. I have some hair algae growing really well in the display now (tank is about 7 months old now), so instead of panicking and adding vibrant, fluconazole, etc. I threw 4 small urchins along with the 10 large trochus snails already in the tank. I skim a little more wet now, and feed a little less. If the algae gets too close for comfort on any corals, well I just scrubbed it away from them like today actually. Nothing good happens fast. So just waiting for things to stabilize. Plus I expect the copepod and phytoplankton populations to take off. Just be careful trying to correct things quickly using chemicals. Work on biodiversity when possible (using clean sources and quarantine) and give time. Drive your tank slowly and enjoy the ride, dont yank on the steering wheel, it'll cause wrecks.

post a current tank pic pls so we can track progression here and spot any unstated details
