zoas and paly's under t-5's?

[fishboarder]

i have a 6 bulb t-5 setup with icecap reflectors over my 75 and am having issues with my zoas and palys. the bulbs aren't overdriven. anyone else out there running just t-5's having any problems? my lights are about 8 inches off the water. sps and lps are good, but zoas and palys just close up for the most part except for when the lights first come on. should i raise my lights some? right now i have 2 actinic, 3 blue+ and 1 aquablue bulb. just tested the water and everything looks good. TIA.

It could be related to something else, but I ran all UVL bulbs (overdriven w/IceCap) and had this same problem. I switched to all geissman bulbs, which was better for the zoas, but the bulb color was awful after 2 months (no blue). Now I'm using ATI Blue +, and ATI ProColor with good results.

how many bulbs? how high off the water? size tank? sorry for all the questions, just trying to compare systems to see what i can try to fix mine. i had geissman's on my tank and just switched to ati's. i do like the color better.

Heres mine, 8x54watts ( 432watts ) 6 diffrent colors used for lighting ( 420s,460s,3500K reds, 6000Ks and a couple other colors? ) but plans to add Fiji Purples and coral day lights. Its lighting a 100 gallon tank. You can look at the gallery for more pics, pics were taken with a crap point and shoot. I wish I had a SLR to take these pics. Pics aren't as updated, as I gotten rid of a bunch of zoos and palys that I don't have planned going my 37cube.

thanks for the info guys. something else must be off then.

Just wondering if you acclimated them zoa's/palys' properly when they first got into the tank. Meaning, starting them all the way in the bottom then gradually moving the up as the get acclimated overtime.

 

[fishboarder]

yea, they all start at the bottom. some are even shaded.

how's flow? what PH's and overflows etc. are you using?

 

[fishboarder]

flow is good. i have a nanostream 6045, stream 6000 and maxijet mod 1200 along with the return and a closed loop. water is as follows:

alk - 11
Ca - 450
ph - 8.1-8.3
Mg - 1300

looks good there for parameters. Maybe they're just tempermental polyps , just need enough time to get happy in your tank. LOL
