i have some green button polyops or zoos not 100% sure they have long tenticals.. Anyways some have green in the center surround by red and the other have a whitish center with red around them. They are about the same distance down form light fixture (t-5 vho 108 watts). I no i need more light

but i have a pompom zenia that is growing very well under the light and it is below the green buttons.

some seem like they are losing color but just in the center of them??? Should i place them down futher?

 

[mr_x]

you could try that. how far are they from the bulbs?

 

[tdog7879]

they are about 8 inches from bulbs

i would move them around till you find the right spot for them. don't go by how the xenia reacts. xenia is funny...it can do well under low light and very high light.

i move a small frag down..how long do you think it will take to get color back? Does the zoos need high water flow?

zoos like flow just not killer flow. as for how long until they color back up, it could be a day it could be month, it just depends on how pissed they are.

i say a month.
