I am new to this forum but have been reading posts for a while. I had an outbreak of algae, and have stopped any ferts for about two weeks and have tested my phosphates and those are zero and my nitrates are about 15 ppm.

The algae i have is thread algae i believe. Its as long as 5-6 cm and is a grayish green color. I have been doing regular water changes trying to get the nitrates down even lower.

My question is, once the nitrates are down, should the algae go away by itself or will i have to manually remove it. It's everywhere, so manually removing it would be a real pain. I also was wondering if any of those algae remedies in a bottle are harmful to plants.

Welcome to the board MD2B!

Just by your description of the color of the algae, I am thinking it may be staghorn algae. Nothing will eat staghorn algae, and there is no real safe algaecide. The only ways to remove staghorn algae, if it is staghorn algae, is either manually or through patience.

One of the problems you are having is the fact that your phosphates are at 0! We plant keepers like to maintain a phosphate level of around 1ppm. We like nitrates too! Your nitrates are not too high at 15ppm. A ratio of 10:1 (nitrates:phosphates) are what many planted hobbyists try to maintain.

Planted aquariums are about balance. Once you hit it in your aquarium, things will be fine!

Do I need to try to raise the phosphates? If so, how? I guess my question is, will the algae die off with the water conditions being right?
