Food Coloring for that Deep Ocean effect?

Fish are stressed out by psychedelic gravel, so wouldn't psychedelically-coloured water have the same effect?
 
Yeah how would you like it if someone said ok no more seeing things clear you see everthing blue now. That would suck I think it would put to much stress on the fish also the carbon would filter it out so it would be pointless.
 
I think the difference between something not being fatal to a fish and something having a bad effect on the animals are two very different things.

For example in the non-fish realm: red food coloring used to be used in hummingbird food - it was later proven that red food coloring actually causes sterility in these animals.

So just because the fish can survive in a tank dyed with food coloring doesn't mean that it goes uneffected
 
Thats probably why hummingbird feeders come with the clear red plastic unlike before. Red has proven to be very affective in trying to attract HB. I always wanted to try those feeders but Ive heard (on TV) that you fill them with sugar water but wont that atract alot of ants??? Sorry went of topic dueing water just to make it look differant is a bad idea. I give it 2 thumbs down.
 
If you want the blue effect I would go with the Actinic bulb. Most reef keepers use them and they also seem to work with plants to. Atleast it did not effect my plant tank, when I had to use my actinic bulbs when my other lights went down for a short period of time.
I would rather use lights instead of food coloring. IT would be like having a pig farm next door, smelling and tasting it 24/7.

GER - yeah that's why HB feeders are made with red plastic now. itf you hang the feeder froma porch awning or something else ants shouldn't be a problem. you may attract the occasional bee or wasp but they don't drink to much.


To rest of the thread -

i think the blue dye that they use in ponds and such are used mostly to keep algae and aquatic plants from growing as it blocks out certain wavelengths of light.

Gross! Didn't see that before.

Sharyl C brings up a good point--are you keeping this tank planted?
