Algae- Good or Bad?

Algae is good for the tank's ecosystem but it should be scrubbed off the glass surface. Fishes like to eat algae.

Everything depends on the kind of algae that's growing in your fish pond and in what size they are. Also, the kind of algae that's growing matters a lot. Just like Plankton algae is very good for the ponds ecosystem.

How often do you clean your tank? If you aren't cleaning your tank often enough and if your pump isn't strong enough, you'll get algae. You want that perfect balance in the tank and that could take some discipline and careful watching.

I think some is good but you have to make sure you have fish and other creatures that eat it in the tank.

Otherwise, you will want to remove as much as possible or you will end up with overgrowth which can be hard to get rid of.

Generally Algae helps in stabilizing the aquarium. Brown algae and green hair algae are very beneficial for additional filtration of nitrites and harmful toxins whereas staghorn algae is harmful to the fish tank.
