SPS Dying

[Howieumd]

I was just wondering if anybody might know what could be causing these particular pieces to die? My parameters and lighting are just as stable as they've been for months.

Over the past few days, these particular pieces seems to he dying one or two branches at a time per day. Every morning I wake up and an additional branch on each colony dies.

I thought maybe red bugs, can't seem to see anything though, but did dips in Bayer 2 days ago and it still is happening. It fully happened to 2 additional colonies a few days prior to when theses 2 started. The rest of my 60+ pieces don't seem to be effected yet, so trying to figure out the problem and remedies before it gets worse. Thanks!

I would guess its flow. Acros need big flow. If they had the correct flow there would be no sand on the bottom. So being where they are now they have slowly asphyxiated so to speak..

Thanks. There's a little flow down there, but I'll have to move them up. Think they'll rebound if that's all it is?

Yes they should come back. The flow acros like would make your hair blow back. in a swimming pool it would knock you down.
If you can get some good polyp extension, you'll be able to see the polyps move.

Are these freshly added to your system? Most of the time people purchase these acronyms colonies and don't account for the flow that they need and so you get all this loss

These ones have been there for about 2 months. I had one of my MP40's blowing lower but raised it a few inches a few weeks ago to stop the sand dunes.

they have to be off of the sand

Thanks for all the replies. Quick question, is there a good profile to use for SPS tanks for the poweheads? My Vortechs dial down to 10% between Midnight and 7am, so I'm guessing that might also be an issue? Here's a pic of one of the profiles, the others are all set the same.

Also, on 1 side I have an MP60 and the other side has 2 MP40s, on an 8' tank. I was considering changing to 4 WAV's (2 on each end) and moving the 2 MP40s to the back wall and selling the MP60. Just wondering any thoughts on that before I do it? Thanks again.

What size is your tank? I'm having similar problems and would be happy to compare on flow.

I'm running a standard 120gal.

It's 390 gallons in the display. 8' long.

Yeah man, you need your tank rip roaring with current! They are asphixiating in the low O2 environment at night. I'd up your flow substantially during the night.

I personally don't subscribe to that low flow at night theory. The ocean doesn't slow down especially on barrier reefs, where staghorns and acros are, just because it's night. Your tank's oxygen is at it's lowest at night so it becomes increasingly important that your thin skinned SPS get adequate water movement to facilitate transfer of CO2/O2.
