    IMO a 10 000K 250W MH will be to strong for most softies and some lps. Rather go for a higher kelvin MH as they have less lighting "power". The higher kelvin globes don't produce as much par as a 10000K and they make the tank look a lot better.

    I would recommend 14 000K lights then. 10 000K is yellow and 14 000K is a crisp white. It does depend on what brand of globe you use as well.

    It depends on the sand you are going to use. For playsand and sugar fine aragonite it is recommended to go for a depth of 150mm. The bigger the sand particles the deeper it needs to be...

    I wouldn't go deeper. It might cause some problems. Rather stick to the tried and proven 1500mm for play sand...

    Charl - for that size tank, one times 150 watt metal halide, 14000K with 2 x 39 watt actinic/blue T5's would be perfect. You don't need any more...... I agree - 250 watt would be FAR too much overkill - you would have heating issues, and issues with coral bleaching if you would go 250 watt over such a small size tank....

    It's the W (The power) and not the kelvin (Kelvin is the colour of light that the globe emits: 6500K (Yellow), 20 000K (Blue)....
