Most fish only require enough light so they can tell night from day.

It might be possible that a little more light and longer days along with warmer water might encourage breeding.

But for growing out fish to eat, they don't need sun tans, keeping things dim or dark is just fine.

they seem less stressed without light. I currently have 3 - 55 gallon tanks in my basement, and I leave the lights off most of the time. they just seem happier and they eat more/better.

I just read all 51 pages on this comment wall - yep the eyes are a little red right now. Thanks to everyone who shared I have learned a lot  

I did not see anything talking about sensitivity to light. I have 19 tilapia in a 55 Gal drum it's black, and there isn't much light getting in there - will this have a negative or positivie affect on the fish? They seem happy but then again I'm new to the whole fish thing so might be misreading the signs

Randall, you are going to be just fine. I just had me a litter of tilapia and actually you want them to be out of the mothers mouth and her put away. Now all you have to do is grind up some flake fish food as small as you can get and then put a little into the tank, they will see it and eat it all up. You dont have to get them any special food unless you want to. I use the TetraMin tropical flakes for the little babies. As they get bigger you wont have to grind the flakes up as much. Rob is correct about the tilapia being tough as nails. Heck I had one mother that I took out of the tank and her babies that still have the egg sac on them was out of the bag and I had no choice but to put them in a small 10 gal tank and they did just fine. Some breeders do what is called stripping of the eggs from the females and put them in a bubbler so the eggs get a constant movement as to not build up fungus and they hatch out in the thousands without the mother at all. The little bubbler setup does what she does with the babies in her mouth.

dont fret the build up.. they will get to it. you can turn off the filter and just aerate the heck out of it for now. or just keep a sponge or screen on the filter intake and clean it often, they will do fine. thats the beauty of tilapia... tough as nails.

Randall, they should be fine. they only need her to protect them from other fish. Now you will need to feed the little guys... i have given them the slug from the bottom of a grow bed, smashed feed, algae, etc. but all three would be a more complete diet.

How can I test my system for fluoride in the water? If I have high levels what can be added that will remove it? Like ascorbic acid remove chlorine.

I just picked up 5 females and 1 male to put them in a aquarium for breeding. When I was sexing them and then putting them in the aquarium (they are normally in a pond), one of the females let some eggs fall. 

But they then dissappeared. Before that, she just left them there. SO i'm not sure if they were eaten or not. But if this happen again and she doesn't pick them up, should I collect them and put them in a small aquarium? Or leave them there?

Also a use point she told me that it only takes a very small amount to clean up allot of water so dont waste it by using too much, using more than you need dosent make the water any more pure.

Believe it or not Sodium Thiosulfate is just a chemical that the old professionals use to develop film; you see it in the old
movies where they drop the photo in the water to watch it develop under the red lights. I only know this because I had a friend a long time back and I was asking what to use to get the chemicals out of my water for the fish and she gave me a pint jar of the stuff for free. I used it then on tropical fish and plants in a system I was setting up for raising tropical fish and everything thrived, but I have never used it under the guise of going to eat the plants and fish. It seemed to be safe for use but some research would need to be done before I would ever use it in an aquaponics system.
