Very slow coral growth

[Triggerfish]

all parameters seem ok except mag is low like 880.
frags just dont seem to grow. green acro, caps, digis, only growth i noticed was red setosa is spreading a bit. all polyps extending and color seem decent. running a 175 15k(6 months old) about 8" from water. LPS slow growth as well.
im thinking of going to a 250w thinking that may be what is needed.
what do you folks think?

Get the mg up. Also make sure your Ca is good with Mg so low Ca might be low too.

And frags grow slow, the bigger they get the faster they grow IME.

I'm new at sps so take it for what its worth.

You might be new at it but I would say you have the concept down.

so just low mg alone is causing no growth?

I thought mine wasnt growing either until i looked at pics when i first got them...

quite possible! have you tested your calcium. If mag is low 99% of the time calcium is low too, which entitles slow growth as well as high alk.

Get Parameters stable then wait, patience is the key, lol

Maybe there is some detritus between the braches.
