coral growth

[fishguyxd]

I have always wondered why when I look at other tanks and hear everyone's corals are growing like mad you know can keep up with them (xenia or others) even after 6 months they say it just started out as a frag and now it's the size of a grapefruit or bigger So what is my problem I try to keep my water within the scope ph 8.2 ,salitity 1.023 or a bit higher Calcium say 400ish and low nitrates etc. Alk or dkh is the one i have not followed closely.
heck my zoo's take forever to sprout newheads and no I do not have my fish nipping alot. I have had the lights on alot example 12hrs on ( pc light currently). I have had some growth on corals but nothing close to others.
Should I be adding something??
So can anyone throw some idea out???

Lights. That's my guess. Things grow like snot in my nano (MH) but almost don't grow at all in my 55 with PC lighting.

The difference is really quite something.

Thats' my 2 cents.

lighting man. gotta have light, and lots of it. metal halides work wonders.

I second the light being your main problem... Just a little tip to get zoos to grow a little faster its IMO that zoos prefer a little dirtyer water than most coarls... I now only do water changes every second week and the zoos seem to be growing leaps and bounds now .... there are a few threads about zoo growth on RC

I would guess lighting, possibly a new bulb, and flow.

How about a full tank shot?

Have you tried taking photos of your growth, say one ever 3 weeks? Sometimes you don't see th growth because its happening right in front of your face.

What kind of corals? Just softies like you've mentioned?
