What are harmful effects on algae to aquatic ecosystem?

Answer 1

The detrimental qualities of algae to the environment is that it produces toxic substances which are released to the ecosystem. However, algae is also beneficial in various ways in the environment.

Answer 2

Marine and fresh waters teem with life, much of it microscopic, and most of it harmless; in fact, it is this microscopic life on which all aquatic life ultimately depends for food. While most of these species of phytoplankton and cyanobacteria are harmless, there are a few dozen that create potent toxins given the right conditions. Harmful algal blooms may cause harm through the production of toxins or by their accumulated biomass, which can affect co-occurring organisms and alter food-web dynamics. Impacts include human illness and mortality following consumption of or indirect exposure to HAB toxins, substantial economic losses to coastal communities and commercial fisheries, and HAB-associated fish, bird and mammal mortalities. To the human eye, blooms can appear greenish, brown, and even reddish- orange depending upon the algal species, the aquatic ecosystem, and the concentration of the organisms.

These outbreaks are commonly called red tides, but scientists prefer the term "harmful algal blooms" (or HABs). The term red tide erroneously includes many blooms that discolor the water but cause no harm, and also excludes blooms of highly toxic cells that cause problems at low (and essentially invisible) cell concentrations. Therefore, harmful algal bloom is a more appropriate descriptor.

Answer 3

There are only disadvantages if you have too much of it in your tank. When the amount of algae becomes overwhelming, it will start covering up your plants (if you have plants) which will give them a harder time to absorb any nutrients or light. A lot of algae can also be an eye sore. You can have a minimum amount of algae to give your tank a natural look, but maintain it so it doesn't become too much. It is natural to have algae, and there is no way from avoiding it. I personally love having algae stuck on my decorations because it gives it a more natural and time elapsing look. I suggest you scrub off algae using some scrubber or sponge every time you do a water change. It will come back, but you are maintaining it.
