Moonlight advice

I fitted some moon lights for my marine tank but they're a bit dark. I got two LED strips of actinic lights but I need some more white light. I was thinking of getting one or two LED spotlights in addition (something like this: www.miniinthebox.com/submersible-underwa...um-rgb_p4924422.html ) or I could just get one more LED strip, but white this time.

Anyone have any thoughts on spotlights versus strips? The lights are just for morning and night, when my main T5's are not on. The tank is a 180 L reef rank.

I find these: www.maplin.ie/p/replacement-cold-cathode-tube-blue-a91ak

to be very good for my south-american tank. It keeps the hatchets from de-tanking when lights go out, but also provides enough light to figure out where things are in the dark. The kit with one blue, one uv and the inverter is under €20. I leave it on 24/7.



P.s. A tube lasts about 3 years like this.

Hi Robert, they're not for night, they're for day, before the main lights come on at 4pm, and then after midnight for a while before I go to bed, so I need them low enough to prevent algae growth and give the fish a break, but bright enough to enjoy the tank! :)
