Give us a timeframe..
Been growing SPS for ? months now Have had corals that haven't shown growth in ? months.. Often times SPS growth is slow.. Sometimes taking pictures and comparing after a few months is the only way.. If I had to get "picky" your alk is lower than I would suggest if SPS growth is your target.. You could be 8.5-9 (or more) with your nutrient levels easily.. Same for calcium.. And of course lighting.. Got a PAR meter? Some report great results with CBB lights.. others not so much.. Thought about T5 supplement?

I don’t know much about the lights you’re using but your alkalinity and calcium look a little low. I’d (slowly) raise the dkh and calcium - maybe try dosing. That being said acros are terrible slow growers so maybe you just don’t see it yet. One final note - I’ve never owned acros or similar to take my advice with a grain of salt, but that’s what I’d say based on the information I’ve gathered by experienced reefers.

Alk is low, I run a 65g with two Visparspectra 165w.
Your PH is likely a bit on the low side as well. Not the best lighting for Acros, but easily grow all else. T5’s seem to produce better growth and colour. I would increase Alk to 8.5 over a few days, |

So the alk on Red Sea is 8.2-8.5 yet your alk is only 7.3 - I would start to dose some alk to bring you tank level to your salt level. Dose calcium also. Bring nitrates up a bit maybe with some ME polyp extender (will add aminos). How is your flow?
Cheers! Mark

I always thought it mixed a bit higher - my bad!

I am thinking of adding (2) ATI T5's along with my 2 Vipars 165w. tank is 4' long.
what is a good length for the T5's? I was thinking 1 coral plus and 1 blue plus. |

Yup, I think that's a great idea, the 1+1 will diffuse your light, that's mostly the problem with individual LED lights like VIsparspectra, this configuration does not blend the light well. In addition, the intensity and colour mix is preset. |

I use T5HOs & love them for coral growth over LED any day, don't short yourself get the 4" fixtures & bulbs or else the tanks ends will suffer. They spread the light wonderfully but its reflectors spread the light in width for no shadowing, not length. If you go a foot short that will give shadows at the tanks ends.

I've been experiencing the same thing---slow growth
Hi, i've just returned to the reefing hobby and completely new to SPS corals. My parameters:
1.026 sal 450 calc 1370 mag 9.2 ALK hydra 26 for a 20g shallow nuvo My problem might be time---i've only been running this tank 2.5 months (but bought tank established so livestock started right away)--- I have noticed that keeping a close eye on them, corals will let you know if something else in the tank is affecting them. I recently treated my tank for red cyno bloom--and the algae bloom seemed to be affecting the oxygen intake for the corals (seeming to choke out the small polyps)---treated the tank, SPSs are showing stronger colors and the small polyps in some pieces are coming back out. I just figure it will take more time to see results. I acquired some larger SPSs from a 3 year old tank. |

Your prob is time.
Each coral must settle. Some take months Parameters must stay stable |

Be sure none of them are wobbling in the current. You might nudge your dkh up at least to 7.9. I prefer 8.3. And lighting. Lighting is major.

I think you will be very happy with the T5 lighting results in a month or so. Good tube choices for the T5s. Take a few pics now then do it again in a month.
