coral growth

[cityreefer]

this is just what happens when i am up at 8:30am on a Saturday, i start over thinking
here we go
i have a red sea max 130, so 34gal altogether. i run the stock lighting 2 55wat compact t5's 50/50 i change them once every 10 months.
i do 10- 15% water changes once a week (instant ocean salt) and top up two times a week with a little fresh water about 1 gallon just to add some seachem reef builder. when i test it is all good kh,gh,ph,cal,mag, ammonia no3 and no2, phos
i feed my fish once a day and my frogspawn once a week.

i know my tank is not big but i would like to have my corals grow faster? is this a normal growth rate coral list below:
frogspawn
colt coral
finger leather
cabbage leather
pulsing Xenia
GPS
toadstool leather but this is just a frag so not worried about it yet.

any help would be great!!
