can u have to much light

[ginnboy]

can you have to much light for zoas, to make them close up and die.my ric are also real small,smaller then when I got them. I have the nova extreme pro 72" on my 180

 

[robertmathern]

water perams please. I dont think it is you light.

 

[sickboy]

That light has 468 watts right? On a 180 that would only be around 2.6 watts/gallon. So, I don't think too much light would be your problem, maybe not enough light. How high in the tank were the corals?

 

[ginnboy]

ph 8.0, nitrate 20, nitrite 0,cal 420,alk 300ppm

I have tried high,med,and low placement all the same resorts

 

[nycbob]

its not the light. r u using tap or ro water? i suspect its got to be the water.

 

[sickboy]

What else is in the tank?

 

[ginnboy]

I use ro water .I have mushrooms and some candy cane and some yellow polyps all not speading like they should.I was think it might be water too ,I was adding iodine for a while ,but stopped when the problem started . could my iodine level be to hi and cause this

 

[nycbob]

u dont need to dose anything if u do weekly water change. ur corals r fairly easy to keep, so dosing will do more harm than good.

 

[ginnboy]

Im going to test for iodine and take a water sample to lfs and see if we get the some thing

 

[sickboy]

No fish?

 

[ginnboy]

oh yea I have a yellow tang ,potters angel ,singapore angel, pj carnial, mandrine,sandsifing gobie,copperband butterfly,and 3 small gobies

 

[aquaguy24]

have u been keepin an eye on ur angels or your butterfly fish..those are known to eat corals..

 

[ginnboy]

they are not even nipping at anything,they eat flakes and frozen food

 

[osubeast]

Didn't someone mention something about flatworms or other worms maybe irrating things. Have you checked any of these?

 

[ginnboy]

yes I did have flatworms awhile back but not lately,Im thinking it's more of a water thing now. Im going to the lfs tomorrow to let them check my tap water ,ro water, and my tank water to see what they can find.

 

[mr_x]

it's not flatworms. do the closed polyps have any white spots on them?
how long ago did you add the nova fixture?

 

[ginnboy]

no spots and the lights are 8 months old

 

[mr_x]

so you are saying that nothing has changed at all in the last 8 months?
change salt?
change lighting schedule?
change waterchange frequency?
temp change due to warmer climates?
new, or different flow components/powerheads, or lack thereof?
anything i might have missed?

 

[ginnboy]

I upgraded to a 180gal 8 months ago from a 55gal,Im doing everything the same now as I was then .
