No but it can be problem sometimes. There are algaecides that can be added to the water when filling a bed that will prevent it from forming and growing.
No, pollution of the water is what causes the green algae. When extra nutrients such as pesticides, runoff, & human/animal waste are added to the water, it in a matter of speaking, makes the algae go nuts. The algae starts to grow in vast, huge amounts. The algae clouds the top of the water, blocking the sunlight that all the plants and animals need. When the algae dies it covers the grass beds and destroys the aquatic plants and animals' habitats. The only real way to stop the algae is to quit polluting the bays. oceans, rivers, etc.
Brown Algae
brown algae (A)
Although all algae have chlorophyll not all kinds of algae are green. Fire algae are unicellular algae that are red in color because of too little oxygen in the water
Algae is a water purifier and will not kill Guppies at all.
Algae absorb nutrients or chemicals from the water source, thereby keeping it clean by removing contaminants. ADDENDUMAs is not nice in the world of algae good works! If algae proliferate when nutrients are high they may die off when conditions change. The masses of rotting algae (algae blooms) rob oxygen from the water and kill fish and give an off taste to the water. The floating, rotting blooms are aesthetically unappealing. Secondly the algae may remove contaminants like heavy metals from the water, but they concentrate it in their bodies. The algae die and precipitate toxic levels of the heavy metals on fish spawning beds
There is some Blue green algae in nearly all water especially fresh water.
Algae draws all available CO2 out of water, causing its pH to increase.
There would be a larger population of algae on the earth.
Green pool water is caused by algae. To remove the algae, bring the pH level of the water to 7.8, scrub the sides and bottom of the pool, shock the water with chlorine, then vacuum up all the dead algae.
Red algae is the only algae that can survive in the deepest water
Algae are produers in water ecosystems
