Dodgy Guy Posted July 30, 2005 Report Share Posted July 30, 2005 ok sorry for the corny subject line! there is no camera or action! just wondering about lights. i would like to bring the colors out in our fish more. a UV light would be reall cool BUT are there any side effects to the fish? also would a blue light (non uv) bring colors out any better or worse? we dont wanna give our fish cancer or anything! cheers Dodge Quote Link to comment Share on other sites More sharing options...
caserole Posted July 30, 2005 Report Share Posted July 30, 2005 I hope I have read your post wrong because uv lights are very dangerous for your health let alone the fish. Quote Link to comment Share on other sites More sharing options...
Snowman Posted July 30, 2005 Report Share Posted July 30, 2005 A uv light would work great but you will have to batter them first LOL Seriously a uv light will kill your fish pretty quickly, imagine your self being under a tanning light for 12 hrs, uv lights kill germs which are living organisms so will do the same for your fish, a red or maybe a blue bulb would compliment a white light bringing out the colours.

Dodgy Guy Posted July 30, 2005 Author Report Share Posted July 30, 2005 oops :oops: well i thoguht if they have them in night clubs..... so a blue light would be better? Quote Link to comment Share on other sites More sharing options...
DiverJohn Posted July 30, 2005 Report Share Posted July 30, 2005 To start with Just add some MORE lights. Cool whites will be fine if yuo just want to see a bit more colour. But what colour gravel have you got?? IMO dark gravels bring out the colours more. At the very least it stops light being refelcted into your eyes and you get to see more of the fishes colours.

fishy family Posted August 10, 2005 Report Share Posted August 10, 2005 this post got me thinking... I have light gravel in my planted tank but would like dark. Not wanting to uproot everything just wondering if it would work to do a layer of dark over the light? Would that make a difference, I was thinking of putting it in a handful (scoop) at a time. Did that make sence or am I up too late. :oops: Quote Link to comment Share on other sites More sharing options...
Snowman Posted August 10, 2005 Report Share Posted August 10, 2005 Can't see a problem with that, it's how i would do it anyway LOL Quote Link to comment Share on other sites More sharing options...
discus haven Posted August 11, 2005 Report Share Posted August 11, 2005 Try an '840' cool white bulb. I get mine from Cory's Electrical. Brings the colour out great. Quote Link to comment Share on other sites More sharing options...
Dimsum Posted August 13, 2005 Report Share Posted August 13, 2005 oops :oops: well i thoguht if they have them in night clubs..... so a blue light would be better? I think you are refering to black lights, they look purple but don't really emit light. But when they shine on certain colours they glow. Like the lights used to find invisible security inks.

Faran Posted August 13, 2005 Report Share Posted August 13, 2005 True, has anyone fitted these on a freshwater tank? I know they use them on saltwater tanks (or something that does the same effect). I'd be keen to try a UV blacklight on my tank, just need some opinions on whether it's safe or not... Quote Link to comment Share on other sites More sharing options...
Caper Posted August 13, 2005 Report Share Posted August 13, 2005 Wish I could add aother light to my 29 gallon tank. The one thing I like about the incadescent in my 10 gallon is that the entire tank is bright so no matter when my fishie are I can see them just fine, not so in the 29 g. My 29 gallon has the 1 florescent light, which took a little getting used to after the incadescents in the other tank. But, the only thing I don't like about it is if my fish are near the front (or not directly under the light) you don't see their colors like you do when they are right under the light Quote Link to comment Share on other sites More sharing options...
klaymann Posted August 18, 2005 Report Share Posted August 18, 2005 simple .. move the light unit to the front of the tank so that it shines back into the tank... plus add an actinic marine tube ( blue) ... late at night just have this on ( at the front too) your cardinals/neons glow like nothing before Quote Link to comment Share on other sites More sharing options...
