A few lighting Questions?

[Helen Louise]

Sorry to bombard you all with a load of questions

How often should you change the tubes? the tank will be a Mbuna tank so no plants!

Which type of lighting would bring out the colours of the fish? the substrate is sand & Tuffa rock as a background,

How many tubes should I have to bring out the best? tank is 36L x 17H x 15W

Can you leave a Blue Moon light on all night?

you should generally change tubes every 12months.
if you have no plants, then you will probably get away with a bit longer than that, but if you start to get algal blooms, it's probably time to change.

i personally like the very white lights, rather than the yellow ones.

you shouldn't need more than 1 or 2 tubes.

I wouldn't leave a light on all night.
