Conclusion
After researching and comparing Fluval Stratum and Bio Stratum, I have come to the following conclusions.
If you are looking for a substrate for a nano tank or one with delicate roots, Fluval Stratum is the better option.
Its smaller grain size and reddish-brown color make it ideal for smaller tanks and plants that require gentler handling.
On the other hand, if you have a larger tank or are keeping shrimp, Bio Stratum is the way to go.
Its larger grain size and highly porous grains allow for better water flow and oxygenation, which is important for larger tanks and shrimp keeping.
When it comes to price, both substrates are similarly priced, but it’s important to note that Bio Stratum is only available in larger bags, so it may not be the best option for those with smaller tanks.
Overall, both Fluval Stratum and Bio Stratum are good substrates, but the choice ultimately depends on your tank’s specific needs.
Consider factors such as tank size, plant type, and water flow when making your decision.
