I've read a little bit about people using various methods to created simulated nighttime lighting in their tanks, or perhaps more accurately, using certain effects to allow their fish to be seen without having the big white fluorescents turned on. I've heard of some people using black lights, some people using actinic (blue) lights, and one guy even using those little lighting effects kits that have suction cup lights you put all over the inside of the aquarium. Seeing as how I'm a night owl and oftentimes am up past my fishes' bedtime, it'd be nice to be able to see them without disturbing them too much.

I have been kicking around the idea of getting a 13 watt AH Supply kit with a blue bulb for night time viewing of my fish.

That is a great link ridns... thx

It would be great to be able to watch the shrimp's in that type of light.

Even at just normal room light (without the tank lights on) they get more active but after the lights all go out they just go marching around the tank like they own the place. They also molt only in the dark it seems... only seen it once !

Please dont tell anyone but I have been known to watch the tank with a penlight at 2 AM ! ops:

I'm using a 13w PC kit with an Actinic bulb. Works great.

Uh...in what size tank? If it's a 5 gallon, that seems like quite a bit of light for nightime viewing. If it's a 175 gallon, does that really do enough good?

Did you check out my thread in the DIY forum here?

http://www.plantedtank.net/forum/viewtopic.php?t=1148

I think I was fairly complete with the setup, I can walk you through it if you want. Also consider the cold cathod tube option since you have a bigger tank than I.

Yeah, I read it a while back and just re-read it (even visited the PC Mods site). What exactly are cold cathode tubes usually used for? Just making your computer case light up or something? Do their $15 deluxe kits include everything I'd need to put one of these things in my aquarium and dim it at will?

Yeah, cold cathod tubes are used inside computer cases, for computer nerds such as me. They also have sound sensitive ones that beat to sound, though their application for aquariums are limited.

If you click on the more... next to the deluxe kit, it describes that it includes. I'll copy it here to save you time(this is for the blue tube):

PCI Switch Plate (see picture). No Cutting Required Jam Nut Switch Still Available Separately, see below.
Boxed Inverter The boxed inverter improves safety and provides for a nice finished OEM look.
Endcubes Top Quality Finish is a number one priority here at PcMods. The endcubes that we utilize provide an excellent mounting surface. It looks great and is functional too.
Velcro fasteners Don't use double face tape to hold on your cathode - use velcro to make it easier to remove it when needed.

To dim, you would need to get a variable AC/DC adapter where you could adjust voltage, and you would need to cut the wires to the molex connector and attach them to the adpater. That should be it.

Just keep in mind, a one color spectrum is hard to view your fish. You might want to get another red cathod tube. The advantage is that these can be dimmed, but LEDs are cheaper if you get them online(ask them to just stick them into an envelope, instead of UPS or Fedexing it)and consume less power.

This is on a 250 gal.

The idea is to simulate moon light. I'm not trying to do any "good". Just trying to make it look nice at night and provide an artificial moon for the fish.

Doomer,

I think we all understand exactly what you're trying to do (hence my title of the topic). I was just trying to get a Watt/gallon ratio in my mind.

Sorry, got no idea about the watt/ gal. ratio. I just eyeballed it and it looked ok to me. It doesn't light the entire tank, just the area directly below it which is what I wanted. Don't think I'd want anything brighter than 13 watt as it would ruin the moon effect.

Looks cool with the fish swiming in and out of the moon light.
