Question: Fresh water clams, florite, and algae control
Hello everyone, I am seeking advise about planted tanks and freshwater clams. I have a 10 gallon planted tank that contains one Emperor Tetra and three other Tetras (can’t remember the names). I have only two plants in the aquarium, Petita Nana (Anubias barteri 'Petite') and Java Fern (Microsorum pteropus). The Petita Nana is attached to the TetraTech Power Filter intake and the Java Fern is attach to drift wood. I use Florite for the substrate which has been with the tank since I started it 5 years ago. The temperature is 78. Although I do not frequently test the water, (all though I should) I do perform partial water changes every week.
Question #1 – Florite and freshwater clams
I heard someone state that Florite can be harmful to fresh waterclams, especially since the entire substrate is Florite. I had freshwater clams in the tank before but they do not last longer than 6-months (the same for Bamboo shrimp). Should I cut back on the Florite and mix it with something else?
Question #2 – lighting and controlling algae
Also, every time I use lighting, whether being the regular Fluorescent Fixtures or the Coralife Nutri Grow Plant I get an infestation of green algae. Cleaning the algae on the glass I have no problems with. However, the algae grows on the leave of the Petita Nana (Anubias barteri 'Petite') and it is very difficult to remove. Right now, I solely rely on indirect sunlight. I have notice that I get less algae using the indirect sunlight as lighting than the light fixture. Any advice in keeping the algae in check especially on the plants?
