    bright light

    i would like to keep a acro in my tank the parameters are all fine but in not sure if the light is strong enough i have a 24w compact t5 in blue and white 7200k and a 24w compact t5 both bulbs white 10000k. the lights are 7cm from the surface of the water and altogether 20cm from the highest rock shelf where i am puting the acro. and if the acto survives will it turn brown in the end.
    advise would be helpful

    Hi Ethan

    How long have you been running the tank? I think the key is stability and feeding acros especially hardy species (which are mostly brown).

    I have suspended an acro frag approx 10inches down under three LED lights and I am getting growth out of it. I think this species of acro is rather bullet proof compared to others. It is brown but it is getting lighter and it has white growth tips

    bright light

    iv been runing the tank for 3 months now. I suplement the reef with trace elements includng aragamilk. the PH is 8 and nitrite ammonia nill i also have phosphate removing granules in the sump. About 3 weeks ago i was given a 2in brown acro frag im not sure what coulor it was or is meant to be but the person i got it from has had all his bleach since then. the frag has now turned on the tips of the acro a light lime green the polyps only come out when i put phytoplankton wich also are green. It is about 20cm from the light. BUT i have seen a pink with yellow tip acro for sale in my local shop and i realy like it. The shop owners said that the tank will need a good calciun suplement and low nutrients if it is to survive. with the light they said the acro could bleach but this would probably be more to the lack of calcium or it minght turn brown......

    Powercompact don't really put out a lot of light, I wouldn't be comfortable putting an acro twig under them.

    Have you got good reflectors fitted?<^EDIT^>

    I had an acro under power compacts and it was growing fine - I have the same frag under Aqua ray LEDs and it i sgrwoing well. I am experimenting with suspending the frag upside down to try and get more growth for fragging.

    I am planning an experiment with LED's - comparing growth rates at different depths.

    However sayin that it the tank may be too young as I have a feeling that acros I tried before in my RSM bleached and died - however at the end of its run before break down I have ultra low nutrients and a good amount of age. I suspect this maturity helps......

    Lower light means you need to have excellent parameters and feeding would be key
