The general rule of thumb when stocking a 'Marine' tank, is to allow about 20 litres per 2.54 cm of fish. In use, your 80 litre tank will only contain at the most 65 to 70 litres (not its maximum capacity of 80 litres). So the maximum amount of fish you can safely keep in it would be no more than about 7 or 8 cm of fish. I would say that your 80 litre tank is not really large enough to be successfully used as a "Marine" Tank.
In a marine REEF aquarium nitrates should be kept as close to 0 ppm as possible. In a fish only marine aquarium you should strive to keep your nitrates below 20 ppm.
The simple answer is yes. A balanced aquarium should contain water plants and these need light in order to live and grow. If your aquarium is a tropical one then the lights should be on for around 12 hours daily.
Green aquarium lights can be purchased at any pet equipment store, or at specialized fish stores. Aquarium lights are used mainly to allow the more exotic fish types to survive in an aquarium life style, and therefore should not just use a simple green light, but one that can provide the fishes their needs.
It depends on what kind of aquarium you have. For a tropical aquarium, to start out you should get guppies, or something else hardy that you can find out from someone else. For a Coldwater aquarium, you should start out with regular goldfish. I know it's tempting to get the fancy ones, but for a while, just stick with the common ones. For a Marine aquarium, start out with damselfish. Some other good fish for a tropical aquarium, get most kinds of tetras, Rosy barbs (unless you don't want them to breed), or Cherry Barbs. Other good Coldwater species, weather loach, Shubunkins, and some other kinds of fancy goldfish. For other Marine fish, there's Damsels, and common clownfish.
To effectively implement LED lighting in your saltwater aquarium for optimal growth and health of your marine life, you should consider the specific lighting needs of your marine species, such as intensity and spectrum. Choose high-quality LED lights designed for saltwater aquariums and adjust the lighting duration and intensity based on the requirements of your marine life. Regularly monitor and adjust the lighting to ensure proper growth and health of your marine species.
In a typical water change, you should replace 1/3 of the water but always use tapsafe which you can get from your nearest aquatics store and if its marine remember to add salt too!:D
"Fish" has one syllable. "Fishes" has two syllables.
I would not advise messing with the pH in a salt water (marine) aquarium. If you follow the directions on the particular testing kit that you have you should be OK but messing around with pH is a very dangerous thing to do and may quickly and easily result in dead fish.
A constant, appropriate water temperature is vital to keeping your aquarium's inhabitants healthy. A sudden temperature change can place undue stress on your aquatic life, increasing their susceptibility to infection and disease. A saltwater marine aquarium should be heated to around 72-82oF which equates to 22-28oC. The most sought after Marine fish such as clownfish, angels, damsels, goby's, dartfish etc as well as invertebrates such as crab's, starfish and shrimp are to be kept in water with the temperature between 72-78oF (22-25.5oC) which is worth bearing in mind when selecting the desired temperature for your tank.
Aquarium salt, not sea salt. Make sure it is freshwater salt, not marine salt or iodized. Salt in fresh water tanks can reduce stress and help in healing. Many types of fish including the live bearers and gold fish greatly benefit from it , helping to promote reproducing.

The location of a marine biologist is either in a aquarium, near the ocean, outdoors, or in a area that a marine biologist should be working in if they want to study oceanography. Oceanography should be studied near the ocean, not by a lake, river, nor pond an ocean.
