So I JUST set up my 3.5g yesterday with my adjustable heater, thermometer, sponge filter, cave, silk plant, and some live frogbit and fairy moss floating on the surface. I also introduced my new betta (impulse buy at petsmart
)! I also use caribsea black sand.
The water hasn't been crystal clear like my tank used to be back before I used live plants and when I used normal aq gravel. I have seen planted aquariums that seem perfectly fine and clear.
But the water doesn't seem dusty like the substrate needs to settle. It just has a flat, very subtle greenish tint. Is it from the plants? How do I fix this?
