Newbie help with zoos and mushrooms

[r76davey]

I had a SW fish only tank for years and got into corals this past year after buying a nano cube for my wife with a few zoos. My new reef tank is a 120g with a 30g sump, 900 gph pump with four out put heads. Top of the line protien skimmer p.c./metal halide lights (can't think of wattage off hand but same as show tank that is THRIVING at my lfs). Water quality is exceptional, the only supplements I have been using is B-Ionics.
Plates, discs, brains, bubble and clams are all doing really well (growing, great color etc). Zoos, button polyps and mushrooms look great (good size, reactive and good colors), but I can't get them to spread. I had the tank up for about three months then had to take it down due to a crack and have had it back up and running for about three or four months. The only new growth has been three polyps that have jumped off the button.
Got any suggestions for future growth? :help:

just give them time and rock to grown onto really. shrooms dont really spread if they get too much current.

time and if you have particulate/meaty food you can offer to the palys (if you have them amongst your zoas) that helps them grow faster, shrooms tend to grow fastest in less than perfect conditions so if your water is too clean wghile they wil;l be perfectly healthy they may nt spread as fast due to the lack of consumable nutrients in the water.
Also it can take several months for ceartain things to hit their growth stride especially zoas, and some of the more colorfull morph just grow really slow, if you have a large colony you may not be able to tell that youve gained six to ten polyps on the outer edge of the colony, the easiest way to tell is find a couple pictures a month or two apart and count the polyps marking them off as you go. you may have gained more than you think, just a thought. I do polyp counts often if I feel something isnt growing, usually even the slowest growing zoa adds one polyp every 3 weeks.

Got the shrooms in a lower flow area...Got any suggestions on supplements that I should be using other than the B-Ionics? A guy that I was talking to at my LFS suggested Kent's Strontium&Molybdenum, But I have always been of the mind set that the less stuff I have to put in the better. If I'm wrong and there is something else I need than please let me know.
Thanks All, Rob

Yes the less the better, i mean theirs not a boat in the ocean pouring plankton in every other week

Give it time, i just bought some a month ago and damn things are jumping off the rock everytime i turn around.

oh and actually i would put them in a medium flow area if you want to start the process quicker, i mean if its to strong for them, theyll jump off and relocate right

what about potentially to much light from the MH? I have heard certain corals that prefer lower light than sps can have growth stunted so to speak.
Also watts/gallon isn't important its how intense the light is so it can penetrate deep enough to still be effective throughout the tank
