Browning Acros?? help?

[Jorgens]

First off I'm new at this so forgive me.
Tank background:
180g with a 55g sump refigium. cheato/caluprea
3x250w 10k MH 9hrs 4x96w PC actinic 13hrs
top off with kalk trace elements (about 1 ml per 5 gal of top off)


Ok, I got 9 in last Tuesday 3-6. A couple of them are starting to turn brown. I have 3x250w 10k . There in pretty high flow on the sand bed for now for light aclimation. I was going to start moving them up this coming week.

What are the major contributors in acro DIS-coloration?

trAtes are a bit high at 20 but working on getting them down. everything else is 0 Alk 11 Calcium 440 ph 8.4 .025 salinity

thoughts?

I feed a mush that has phyto and zoo in it as well as clam juice. Its got mysis/oyster and shrimp for the vish and the whole lot is soaked in garlic/viatimins.

skimmer?

what do you have for flow?

it is not uncommon for sps to brown out after shipment and take a few weeks+ to color back up

Skimmer is an ASM G-3 a lil on the wet side. Flow is approx 800gph thru main with an additional 800 from powerheads. Closed loop WAS to be installed this weekend boosting another 2500gph but got a bad pump and have to return. Hopefully by next weekend that should be going.

I wasn't sure if they brown After shimpent or how quickly it happens or what-not. so they may still brown even tho everything is ok? What is the best way to get color back?

i'm not sure you can have a 1600 gph in a 180 and have high flow anywhere but directly in front of the ouputs.

you need to up your flow dramatically, and while 2500 gph is a decent increase you need much more than that.

really that much force is needed eh?

Pardon my ignorance but how long has your tank been running? It has that sterile look to it. I would say you have to have a real well established tank to try SPS....But I am just a rookie with SPS.
