> I live in indonesia, and we have abundant sunlight here. I've been trying to culture microalgae for a while, sometimes it succeed but sometimes they just crash, i used a 15 x 15 x 20 cm jar (approx 1 gal/5 liter),  i used dechlorinated water, and plant fertilizer (consisting 15% N, 15% P, and some micronutrien), i usually use the fertilizer at N-concentration 40 mg/Liter, then i aerated them under direct sunlight, them water temp sometimes reach 32 C.

Hard to tell at a distance. Most of us find that culturing "green water"
goes better with some small fish in the container. I suspect they eat the
microscopic filter feeders that are busy eating the algae/Uglena/???

At 32C that had better be a really tough fish! Try a bigger flatter
container with some evaporative cooling. Add Bettas or Gourami babys.

     It was all for naught. Taxation with representation sucks too!
