Our pool was painted a darker color. The theory is the the darker colour will absorb more heat keeping the pool warmer.

I don't think so. The material that is black would be warm.
Black things absorb all light frequencies - that's why the are black, black is the absence of light and since the material absorbs all colours, thus doesn't reflect any, you see black. We see what colours objects reflect.
A white pool liner would reflect all colours (by colours and light frequencies I also mean energy) back into the water. So I'm pretty sure that a white liner keeps water the warmest, as it would reflect the most energy back into the water

Yes black bottom pools do help keep the water warmer but only for about 10-15 more minutes than a regular white pool. The weather has more to do with it if your pools in direct sunlight it will be warmer. But people pick out white bottoms so they can easily see if their pool is turning green, getting dirty, etc.

In theory the answer is yes.
I did an experiment in high school where I had soup cans with thermometers in them. I painted one black, one white and one bare. The black can won.
But there are other considerations such as how much of a heat sink the concrete on the bottom of the pool is and if the water is replaced with a cooler water at a higher rate. I suggest you ask around and see how your pool compares with others.

Yes. The walls of the pool will be warmer, and the water will pull the heat away from the walls, thus warming the water. There will not be a significant difference, especially on a larger pool, but there would be a difference.

I personally love the way sand looks in aquariums. I'm twelve too, and I love fish. I tried sand a while ago in my aquarium, but my filter kept sucking it up and getting clogged. Well, now I have a smaller filter, but I decided to use gravel this time. The things to watch out for when using sand are: - Fish and Invertebrates that will kick up sand (Your filter will get clogged) - Using too strong a filter (Your filter will suck the sand up) and - Using the wrong sand. (Most people think that they can just get sand off the beach. Sand on the beach is very bad for your fish tank. If you are unsure of where to get your sand, then buy play sand at your local hardware shop. It is really just the same thing as aquarium sand, but much cheaper. All you have to do is rinse it really well, and you are ready to go! If you have any other questions, feel free to email me. Good Luck!

Yes. It sure does. Do a simple test. Put a black shirt on and go out into the sun for a few minutes. Go back inside and put a white shirt on. Go back outside and feel a world of difference.

Black ink in the water will be more effective.
