🌿 Transform your aquarium into a thriving aquatic paradise!
FLUVAL Bio Stratum is a 2 kg lightweight, porous substrate designed to promote vigorous plant growth and vibrant coloration. Infused with dormant nitrifying bacteria, it activates upon water contact to rapidly reduce ammonia and kickstart the nitrogen cycle, stabilizing new aquariums. Its fine 1 mm granules prevent compaction, allowing delicate roots to spread easily while enhancing biological filtration for superior water quality.

Very good overall
Very good overall.Good nutrient densityAll my plants stated root development (low tech, no CO2 setup)Size of the granules is good - not too big not very small.Appearance /Aesthetically pleasingI used 2 kgs for 54l tank - slightly shallow. Should use 1.5 bags for it to really have carpeting, background and deep rooted plants.1 minor drawback: it releases so much loose minerals even after 2 washes snd 72hrs of filter running. Finally had to do 2-3 50% water changes.That 1 star was reduced for lack of instruction covering that you need to wash the medium.Warning: don’t introduce fish until alert 15 days of cycling!

Not for soft water!
Please be aware that this substrate is designed for hard water, and is not really suitable for using if you live in a soft water area (or use soft water in your tanks). The combination will crash your PH and risk crashing your whole cycle, and it’s a struggle to bring it back up. I eventually added crushed coral which is helping but my other aquarium where I just used cheap pond soil does so much better!I thought this would be easier, but it’s a pain to rinse clean without it breaking down and tends to emerge from the sand cap when I add plants (see the black dots in my photo), whereas soil does not.I’m sure it’s great under certain circumstances but it’s not quite what I needed, and I don’t think the info provided here makes that super clear for newbies to the hobby.
