I'm a new member in this Forum. My tank size is around 60l with four goldfishes of 3-4 inches long, two Java Fern & one small Anubias barteri plants. But the problem is that the Java Fern & Anubias plants do not grow well, tank glass has green algae and the tank water look green. The Java fern plants look dark green and the leaves are not in good shade. When I buried solid iron fert in gravel, green leaves would appear. My light system is 48W and 5hours of light are provided to the tank daily. I don't have a CO2 system, and liguid fert with micro nutriet is added once a week according to instruction. My filter system rate is around 400lph, and my substrate is gravel only. 1/3 tank's water is replaced weekly, the PH is around 7.0 and nitrite level is around 0 ppm. And I don't have test kits for another parameter such as nitrate.
Is the light system too strong ? Should I add CO2 replacement such as Excel ? Should NPK macro nutrients be added together ? Which one should I try ?Pls advise the simple way on how to improve the plant growth and prevent the growth of algae.
