How deep is the tank? How is the color on your corals? How is your water flow?

Depending on the answers you may need more light and/or more/less nutrients in the tank.

Sometimes, you just need a good run of stability to get growth going good. Other times you just need to stop staring at your tank everyday. :)

So long as you are running brand name bulbs that are replaced regularly then lighting is probably not the problem.

If the bulbs are very old, this will have an impact.

I would look at nutrient levels and getting some new/different test kits.
 
the tank dims are 48x15x17

using 2 koralia 750s and a vortech mp10

the colors are awesome!

come to think of it my blue digi grew a whole lot but the others didn't

Your tank looks nice and health, I would just be patient.

This is a long shot but maybe you should run some carbon. There isn't a whole lot of evidence but some people think that chemicals from soft corals could potentially cause problems for stonies.
 
Take pictures too. Sometimes I think some things haven't grown at all. Then I look at a pic from 6 weeks before and realize that it grew a lot. As said looking at my tank for 45 minutes a day makes it hard to notice a difference. But I do have some things like a teal acro that hasn't grown at all in 3 months. Maybe I moved it too often and now its taking longer to settle. As long as your coraline is growing you should be ok.
 
How's your flow? And I use coral frenzy daily and 7-9 alk 400-420 on cal - and have you tryed moving them to new homes? A little magical chairs can help
 
When I had a mixed tank, the SPS corals near my soft corals did not grow as fast. Using carbon will not hurt. You can get a Phosban 550 reactor or the smaller one. It does have a little lip you might be able to hang one back of your tank or something. You will also need a small pump to feed water through it. Don't know your tank specifics and have never used my reactors that way, but I think that could work. Hope this helps.

all I have is hob skimmer and weekly water changes
 
I would puit the carbon somewhere it will get good flow if you decide not to use a reactor

+1 gotta love mh's imo
 
I agree with the MHs but check out the Tank of the Month. It is only run on VHOs. Interesting to see it for yourself on how good that tank looks on just VHOs.
