3 The Equipment

3.1 Water movement

3.2 Heating

3.3 Lighting:

Time to spend more money!
Most lighting can be obtained in reasonably quality second hand at half the new price
Just stick to branded products. Always reckon with replacing tubes or bulbs.
HQI- The brightest and still the best for a reef. The small tubes should be changed annually.
The higher the colour temperature is not better. 10000K is ok. Not cheap.On 8-10 hours daily.
Use in conjunction with blue actinic tube(s) 12-14 hours.
Fluorescents- much talk about the new T5 tubes. The jury is still out on this.
