hello,
i need some help with lighting, i know watts per gallon is really not practical any more, but since i don't have a par meter, i need advice whether having a 150watt metal halide supplemented with 2x39 watt HOT5 is too much for a 90x45x45cm tank which is about 40 uk gallons or 48 us gallons not sure which i should use...
is this just sufficient for a tank of that size or too much?
thanks
