Acropora growth suggestions - Feeding/Additives

[Salt Creeper]

I have a 135 gallon SPS focused tank that I set up about a month and a half ago. I've got some acropora in there that are doing pretty well but I'm seeing little growth in the three or so weeks I've had them. I've got a mille, a slimer and a aucleus at the moment. They are holding color so far and have excellent pe just looking for more growth. I've got all my water parameters spot on with nitrates at 0 phosphate at 0.02 ca at 420 and alk at 8. Now that I've got the water where I want it with reasonable stability I'd like to work on feeding schedule. Right now I'm feeding reef chili and Red Sea reef energy mixed when hydrating the chili. I feed both at 3/4 recommended dosage every other day. My questions are how/what are you feeding your SPS and if nutrient management is not an issue should I be feeding more/more frequently/both?

Here's a picture of my A. Aucleus that I'm trying to get better growth and color out of. If been feeding reef chili and reef energy for about 1 week.

SPS take months to grow, not days.. go slow and keep things stable

If you want mor color, raise your nitrates. IMO, 0 nitrates does nothing any good. I shoot for 5-10 in my tank.

And +1 on patience. You're tank is at 6 weeks or so. I'm just now seeing decent growth and color at 14 months. Nothing good happens fast. Take your time and learn the tank and what it's needs are. I wouldn't dose anything right now personally.

What lights? how many fish do u have. u should have good growth with out feeding. Also it takes time before they start growing take it slow don't rush it. Feed is not going to help much if your prams are not stable witch your tank Wont be stable at a 1 month and a half. I would not buy any more coral until they are growing goods and color

I run Zeovit so have ultra low nutrients, I also do weekly 10% water changes. A few weeks ago I couldn't get my usual water delivery to my house so went 2 weeks without a water change and definitely noticed improved colouration of my corals. I agree that running a small amount of nitrates and phosphates can benefit acro growth and colour.

Interesting on the nitrates.. I would have a hard time getting my nitrates above zero but maybe I'll just feed my fish a little more. Of course I don't expect my corals to grow inches in a day I was just hoping to see something noticeable from comparison pictures from a month. I would say things are pretty stable - having put a bunch of expensive acros in a new system I check my parameters daily. Ca is always 400-420 alk is 7.6-8.0 mg is 1300-1360 ph 8.1 nitrates 2-0 phosphate 0-0.02. I am running a rsm500 system which has a 10 bulb t5 fixture with all acros being about 10" from the bulbs.
