how can i get my zoos to color better

[TeresaQ]

I have several colonies and most are faded and reaching for light. I have a 150gal tank with 750 wtts mh. I am going to add 2- 36 inch T5 for actinic. will this help. most colonies are midway or top of my live rock. I am really considering switching center mh for 4 to 6 - 36 wtt T5 to see if i can improve color and keep them from reaching so much. sorry can seem to post pictures on this site, I cant get them to post in the gallery

so let me get this straight you have a six foot tank with one metal halide over it?

actinic will def help color up zoa but i am still not sure about your
MH can you post a pic, try using photobucket there is an explination on the new to the hobby page.

So you have a 3 bulb MH set up right? 250watts each ?

Surprised that with 750 watts of light that zoo's still reaching up...

I am running a tek 8bulb 54watt/432 watt total and their ok.. not really reaching up

 

[TeresaQ]

yes, three 250 wtt bulbs on a 6 ft tank. Ill snap some pictures tomorrow, my lights areoff for the night

Try some actinics.

how old are the bulbs, SE or DE, what ballast and what brand of bulb? Some bulb/ballast combinations are no better than PC as far as par goes. good luck

Yeah I heard somewhere that Atinics help them color up more...

do you feed them? phyto,zooplex,reefchili??

 

[650-IS350]

I feed mine home grown Phytoplankton..... and some invert target food as well.

 

[akrimmel]

i had the best result using kent's phyto and zoo plex alternating every other day and mixing the reef chili in with it.

I have def noticed more color in mine since i added an extra 50/50 bulb to my tank, my pink zoa's are more dull around the edge of the colony but bright pink in the center, as the edges grow out i notice they begin to color up as the colony expands, its really amazing to watch the growth patterns
