How do I know what substrate is best for my aquarium?

I added colored gravel to my aquarium, having rinsed and stirred it beforehand, but my water is still tinted. Why has this happened?

When rinsing any epoxy-coated colored gravel, use cool to lukewarm water and stir gently. If you use water that is too hot and/or mix too vigorously, you risk removing the protective coating on the gravel and potentially allowing the color to leach into the water.

Why does Fluval natural gravel vary in diameter and color from one bag to another?

Gravel and rocks are raw substances that naturally vary and are impossible to replicate. We recommend mixing two or more bags into the aquarium for a more uniform look.

How much gravel height should I factor at the back of my tank to create a slope effect?

Two inches should be more than enough to create a slope from rear to front (the front should have approximately 1 inch of gravel). Higher gravel at the rear of a tank is necessary when keeping live plants, which grow tall and typically have a strong root network.

After adding Fluval natural gravel to my soft water tank, the pH level spiked. Should I remove the gravel?

Due to the low KH value of your soft water, the gravel increased the buffering capacity of your water (KH) and, therefore, the pH value as well. Keep an eye on your fish and perform a few extra water changes while using a product such as Nutrafin pH Adjust Down to help lower pH. The fish will eventually adapt to the new, higher pH level. Furthermore, given that the water’s buffering capacity has increased, the pH level will be far more stable.

Why did my aquarium pH level rise rapidly after changing my gravel?

Some buffering by natural gravel is expected, but it will have a more dramatic effect on tap water with little buffering capacity (KH). At least 30-40mg/L KH temporary hardness is required to stabilize pH levels.
