    I have

    Tank
    Rena Aqualife 200 x 50
    Dimensions: 201cm W x 51cm x D 70,5 cm H
    Volume in litres: 717
    Volume in imperial gallons: 157

    And its going to be planted etc.

    By default it comes with 4 x 58W (232w)

    I’m looking at least 2wpg so need a minimum of 314w

    So im looking at Metal Halide either a Aquavital or Arcadia range

    Now putting aside the types of tubes etc none are large enough for the tank, so if I got a 100cm one and mounted it so its in the middle im going to have some 50cms on either side not covered
    Are these areas going to be dead spots or am I going completely the wrong way ?

    Thank in advance

    With good reflectors, good CO2 and other nutrients, your current light will likely be fine for all but the most demanding of plants.

    Growth may not be super quick, but algae won't be pouncing on you at any opportunity.

    1.5wpg is plenty in a big tank.

    Hi,
    In addition to Georges comment, halides are not necessarily a must. If the tank comes with a canopy you can modify it by removing the stock ballasts and installing T5. Check this thread: http://www.ukaps.org/forum/viewtopic.php?t=1075

    In a tank that size, you would be well advised to review your filter flow rate requirement and CO2 injection methods first and worry about lighting last.

    Cheers,

    Thanks for the feed back so far for filters im planning two Tetratec EX 1200 External Filter giving me approc 2400 lph

    I have posted elsewere about CO2 and will be addressing that

    Im nearly ready to place an order so want to get the lighting right, im investing a lot of money so dont want to skimp on the lighting.

    Lighting

    Hi Johnb, as George has already said the new t5 lighting with reflectors fitted is just as good as anything on the market, my tank is 5x2x2 with a arcadia luminaire and four 54w t5 plant pros and i have been able to grow more or less any plants i have tried, good luck with your setup regards john

    on the filtration side mate i have a 500l tank and it was suggested that i should have 2 fluval fx5 units on it eg a turn over of approx 4600lph . so if this is true god knows what yours should be.
