Purple Bonzai does not seem happy

[reed_5point0]

Sooo I moved a large decorative coral skeleton out of the tank for the sake of more frag space..and it chaged my flow up. Since then my Acros don't seem happy (over three weeks).


I have had it in the upper 1/3rd of the tank with it a little offset and below a wav pump but not in direct flow. I hardly ever see Polyps fully out. And suspect those are not feeders at the bottom but maybe something inside it...

Tonight I manned up and moved the whole piece of rock to the sandbed, as I see most people keep their GARF Purples low anyways.

Lighting: AI Hydra 26" LED

Parameters:

Alk: 10.4
Calcium: 420
Iodine: .06
Mag: 1500
Potassium: 332

low trace of phosphates and nitrates..running half the recommended GFO in the mini BRS reactor for the tank size.

I almost have too much flow..rating at 5.4 - 7.5 throughout the day in a Reefer 170 (34g) I ramp each wave to about 10% power in the late afternoon. I would love to go higher but I worry about my Bubble / Hammer / Alveopora taking a beating

Here are some pics as I am unable to add any more to my user album it seems to give an unknown error...

I imagine that it's the photo but man that seems like dim lighting...

I've slowly lowered my alk from 11 to 7.8 and my SPS seem much much happier. Perhaps that would help?

If you have low traces of po4/no3, I'd definitely but slowly lower your alkalinity to around 7.5-8. Seems Acropora like lower Alk with lower Nutrients.
