In freshwater aquariums, can too much light produce algae?

    Freshwater enthusiasts are frequently concerned that adding a strong light to their aquarium would result in an overwhelming algal outbreak. Algae are a common sight in aquariums. Excessive algae development is produced by extra nutrients in the aquarium water, not by intense light alone.

    Of course yes, too much sunlight in long duration will always cause a lot algae to start growing in your aquarium especially if if nitrates and phosphate are found in good quantities in your pond. Depending on how intense it is, the water might turn green.

    Yes, any long period of light when it comes to anything that has water in will always cause a lot of algae. Think if a pool in summer, if it gets a lot of sunlight on it, eventually after a little while you will start to notice algae forming in the water resulting in you having to change the water out. The same happens with tanks if you have them in sunlight for too long. This doesn't mean don't let them have any sunlight but try and limit how much sunlight they get to prevent a lot of algae build up.
