    i have seen some par reading on tanks where t5s were still strong to 25 inchs, i havent seen any readings beyond that for t5. but i have to tell you if your to have a hope of pulling off lps on the floor you need ultra high quality equipment.


    the safe setup would be two 250 halides, even then i would recommend very high quality.

    No. I don't want a canopy. And probably won't have much on the floor. But better safe than sorry.

    I think its 18 in width. I don't have alo of floor space with my rock so almosr all my corals will be up on the rocks.

    8 t5 will put out a good bit of heat too scenario is having to buy a chiller even though he went with 6 t5s he has a 90

    The two fans or so that would be in a fixture for active cooling will help dissipate the heat. If you were to go with a Powermodule or an Aquactinic fixture heat shouldn't be an issue, esp on a 100 tall.

    As far as what you can use... If a fixture is up your alley go with a 7 bulb Constelllation or build an 8 bulb retro, I know you don't want a canopy but a retro will save you big time $$. A Constellation can easily go for close to a grand and that doesn't include bulbs.
    Wait your tank is 4 feet correct?

    As a reference 23" or so to my sand bed dead center I have 270 uMol/m2/sec, easily enough to grow SPS.....
    But on the sides where the bulbs end(5' lamps) I have 193 and 119 which could still grow SPS but slower and not as colorful.

    T5 is capable of lighting your tank you just need to plan ahead. Leave the bottom for mushies or blastos or other LPS that don't really need much light!

    Happy reefing!

    Depends on your ambient temp in your house, I keep my house at 70 year round and have 8x54w T5's in a tek light over my 90g and my heater is on alot to keep the tank at 78 degrees

    i agree with you. my house should be around 80 this summer so even if i had to put alittle external fan blowing accross the top of the tank i shouldnt have to battle heat issues..that was also a good point about retro kits being cheaper than fixtures i hadnt considered that. one thing definatly not an option is led...they sure are cool though.
