So my recently added zoa frags are having issues, one has had two die and it has one that is always open with its outside turning gray and the middle has lost alot of color. The other frag has some that wont open and has some that the outside is looking horrible.

Is your light the Coralife lighting fixture? If so, I noticed a big difference with my zoas when I added some LED strips in addition to the fixture. Eventually I removed the fixture all together when I got 3 strips and everything is doing so much better. Unfortunately, my zoas had almost all died off, but 1 polyp eventually became a colony again (amazingly!). I thought something was eating them, turns out it was bad lighting.

I have mine under a zoomed fixture. It works great for my other corals, but my zoas kinda look crappy, well at least to me. What do you recommend for led strips? I would like to grow the coral i have now and keep the few fish i have and move it down to austin but next december i plan on upgrading the tank completely. I will keep the fish and coral and as much LR as possible. I want to get a tank with the same basic setup as the biocude.

I like those. Did you go with the pro strip or just the normal 4 led strip? I was thinking about getting two of the 4 led strips one 12k and one actinic. Any suggestions? I dont have much room since I bought a huge light fixture that cant hold but two bulbs doh.gif but i was thinking of attaching them inside the fixture i have?

Do you think they'd be ok here? And is that enough to make a difference, I dont know much about leds and how much is need

If you can see the boxes and arrows... I just mean inside the fixture

I went with pro strips - one of each flavor (actinic, 12k and a mix) be sure to only use 3 per power supply. They do come with mounts. Initially I was going to mount them to my hood, but just decided to use them solely. Made a huge difference - all corals thriving now!! :)

Moved one of the frags up and they seem much happier, the other not so much... I think it is more than lighting. My monti are all doing very well under the T5HOs. I may do a dip for the zoa frag. Any suggestions? I have heard of doing a peroxide dip or an iodine dip. Also how long and how much water vs. other stuff.

Thanks in advance.
