I personally recommend only using this specific type of gravel substrate if you are planning on having any type of life plants in your tank, especially if you are growing from seeds. This is the most widely used type of substrate in the hobby of planted aquariums.
- Mineral rich volcanic soil
- Stimulates strong plant growth
- Promotes neutral to mildly acidic pH
- Suitable for plants or shrimp
- 4.4 pound bag is good for 2-7 gallon tanks
- 8.8 pound bag is good for 7-11 gallon tanks
- 17.6 pound bag is good for 12-18 gallon tanks
Fluval Stratum is the ideal substrate for stimulating the growth of aquatic plants in freshwater aquariums. Plant roots easily penetrate and spread throughout the substrate, allowing plants to obtain a variety of key, readily available nutrients that will make them flourish. The addition of FLUVAL PLANT MICRO NUTRIENTS will ensure a full complement of essential macro and micro nutrients. The substrate’s light, non-compacting, porous structure is also highly beneficial to nitrifying bacteria, which rapidly colonize the vast porous surface, providing optimal water quality for plants. Fluval Stratum’s inherent properties will help support a neutral to slightly acidic pH, ideal for most plant species and species of tropical fish or shrimp normally kept in planted aquariums. Fluval Stratum also provides new born shrimp with the ideal refuge, allowing them to escape predation until they are large enough to emerge. This highly attractive substrate will not discolor water and helps control organic discoloration usually present when natural driftwood is used.
Step 1: Pour into tank to desired depth, and spread around. ** Special Note: I did not rinse prior to adding to the tank. **
Step 2: Place hand inside tank, and begin filling it with water using your hand as a buffer. Pour slowly. ** Fill only to moisten the substrate **
Step 3: With the substrate moistened, begin planting your plants. Don’t plant them too close or it may loosen and cause another to lift up.
Step 4: Begin filling tank once you’re fully decorated. I use the hand method to buffer the flow of water, and I filled slowly.
There was a “slight” amount of cloudiness but that cleared up a few minutes after turning the filter on. The appearance of this substrate is a chocolate color and will really make your plants pop with their greens.
