Fry tank algae

[Angelphish]

As I asked before, can anyone identify the brown hoppy things on the surface?

Those are small insects that show up when there is an excess of food. If the fish is small or hungry enough they will eat them, or at least try to.

They're called Springtails.

Wouldn't rapid algae growth indicate high nitrate levels, though? The nitrate should be low enough for this to happen, especially in a fry tank!

The tank was intended for fry, but none of the last clutch survived. The tank in now occupied by a flowerhorn. My tap also contains about .25 ppm ammonia, giving the algae more food.

Ah I see.

I was just wondering because my tank has no plants, light comes in from all sides, lights are left on all day and I don't have any algae growth at all, do you think that's down to the frequent water changes?

Natural sunlight from a nearby window is what makes the difference in my tank.

In this case, yes. The more water changes I do, the more phosphate, silicate, and ammonia I put in to my tanks. Like I said, algae is a constant problem for me. San Diego tap water is awful.

I couldn't get algae to grow here no matter how hard I try.

I dont get much algae either, but i scrub it off the tank walls, always.

From what I understand, water in Georgia is very soft. Is that correct?

Extremely. Alkalinity is like zero. I have to add chemicals to it every water change, which increases the pH to 7.6+.
