The Daily Telegraph, UK July 2010 stated that some lakes and ponds in the West Midlands contain blue/green algae caused by the heatwave. This is poisonous. They advised all dog-owners not to let their pets swim in still water. According to the article, the dogs have 5 hours between ingestion and death. One 5 year old Collie had to be injected with adrenalin and was given two and a half litres of fluid by the vet to rehydrate him. So certainly some forms of algae are dangerous.
It could be the most toxic substance in the known universe and still not be harmful unless you're in the habit of licking the fish tank, so I'm going to go with "no".
However, if you are the sort of person who licks the inside of your fish tank periodically, who knows?
Yes, it is possible that algae could kill humans.
Because of a bunch of algae that turned red and make oysters poisonous to eat.
Some of the types of algae are staghorn algae, black brush or beard algae, green spot algae, and green thread hair algae. Other types of algae are green water algae, and black green algae.

Blue green algae or cynobacteria are photosynthetic.They produce their food themselves.
No. There could be a lot of poisonous sea anemones and bacteria inside the algae ocean. You can also get tangled in sea plants when you are swimming.
Algae eating fish are not poisonous to people. However, even the largest varieties do not get very big, so they are not really commonly eaten by humans.
Because of a bunch of algae that turned red and make oysters poisonous to eat.
Cloudy, possibly poisonous water blocking filtration equipment, reduced effectiveness of sanitation chemicals.
Mainly by photosythesis that converted the CO2 in the poisonous early atmosphere, into oxygen.
People and studies have shown that the blue-green algae can be poisonous, cause nausea, headaches, and in severe cases, even death.
Small amount of Copper sulphate (CuSO4) is used in water treatment plant to kill algae and bacteria. In small amounts, it is not poisonous. But it can be fatal in large amounts.

Several factors contribute to the overpopulation of algae which include variances in water temperature and sunlight, oxygen content in the water can speed up growth especially if levels are higher than normal and the abundance of nutrients such as phosphates, nitrates and ammonia can increase algae population.
