    VHO lighting question


    Hi,

    I was just wondering if someone could explain what impact having 4 VHO bulbs over my tank would have instead of just 2 (aside from more lighting and higher wattage)... Would I be able to keep more coral species ? would some species be healthier ? etc...

    Also, does anybody have a link about the different spectrums ? I'd like to read up on this a bit but haven't found much info....

    thanks,
    Nick.

    4 VHO's would give you double the lighting, you would notice a difference in coraline algea growth. I have kept some acro's successfully under 4 VHO bulbs

    I use 4 VHO. 2XACTINIC and 2xdaylights. I keep a clam and some SPS with out a problem. I love the color. Just 2 bulbs wouldn't be much light.

    Re: VHO lighting question

    I kept pretty well every coral with just 4 -VHOs except SPSs and clams. Ive heard there are some clams and SPSs that can be kept under this light but the colors are not the best. My new setup will have 6 VHOs and will be trying some of these Corals and Clams.

    Re: VHO lighting question

    Im redoing my 90 gal AGA tank, will be running 660 watts of VHOs . IJO if you remember I tore my last setup down because of the heart attack I suffered in December. Now that Im better redoing it with bigger sump, refrugium, closed loop instead of a bunch of Powerheads, better heaters, 6 inch sand bed(Southdown). And the list goes on and on.

    Re: VHO lighting question

    Yes I do remember... glad to hear your doing better.  660 watts should do your setup fine.  You going to drive to the US for the southdown?  

    I to will be doing things a bit different with the next setup(90 or 120 aga)  I can't wait to try this southdown everyone is talking about.  I think the closed loop is an awesome Idea... will you be going with a 2 inch drain through the bottom and 2 one inch half returns half way up the back?  
    I'm thinking a 400 watt iwasaki 65k with 2 or 3 VHO actinics will give great color and aweosme growth.

    Actually Vickie from the rag got 300 lbs and I picked it up when a bunch of us got to gether in Toronto. Actually the closed loop is all pvc pipe with strainers in both corners and 2 spray bars across the back. By the way whats prices can you get on SALIFERT kits.
