Fluval Plant and Shrimp Stratum is a volcanic soil substrate made for freshwater planted aquariums, especially tanks with dwarf shrimp, bettas and community tropical fish. It is best for hobbyists who want live plants to root quickly and thrive without using plain gravel or sand.
In real tanks, roots penetrate the light granules easily, which encourages denser growth and better nutrient uptake when paired with liquid micronutrients. The porous structure also gives beneficial bacteria plenty of surface area, which helps keep the tank cycled and stable for sensitive livestock.
The granules have a natural dark look that makes green plants and colorful shrimp stand out, while the non compacting texture keeps the bed aerated for roots. It settles cleanly without tinting water and helps reduce organic discoloration from driftwood in aquascaped setups.
The lightweight texture is gentle on bottom dwellers and shrimplets, but it can be disturbed by large digging fish or powerful filters. It also buffers pH toward slightly acidic, so it is not the right choice for hard water species that need alkaline conditions.
Overall, this is one of the most reliable planted tank substrates for beginners and experienced aquascapers alike. If you keep live plants with shrimp or soft water tropical fish, it delivers healthy growth, clean water and a natural finished look.
Brand: Fluval, Model: 12695, Type: Plant and Shrimp Stratum freshwater aquarium substrate.
Form: Porous granules, Size: 17.6 lb bag, Dimensions: 4.5 x 12 x 19 inches.
Use: Freshwater planted tanks for fish and shrimp, supports neutral to slightly acidic pH.
Choose the 17.6 lb bag for medium to large tanks or deeper planting beds, smaller bags suit nano and betta tanks. Plan for about one inch to two inches of depth for most rooted plants.
Add substrate dry, plant stems directly into the moist granules, then fill slowly to avoid clouding. Avoid heavy rinsing, as it can break down the nutrient rich granules.
Pair with liquid plant micronutrients and moderate lighting for best growth. Avoid mixing with alkaline gravels if keeping soft water shrimp or pH sensitive plants.
Pros
- Superior plant growth and vibrant color from nutrient rich black soil plus root focused supplement
- Buffers pH and softens water to create ideal conditions for plants, tetras, shrimp and other soft water species
- Less algae and cloudy water issues than Version 1 according to experienced users
- Natural dark look and ideal granule texture for aquascaping slopes, carpets and stem plants
- Easy to use for beginners building a fully planted tank
Cons
- Causes an initial ammonia spike for several weeks, so tank must be cycled before adding fish or shrimp
- Nutrient supplement pellets are potent and must be placed carefully under the soil to avoid excess nutrients
- Premium aquasoil with higher upfront cost and may need root tabs over time as nutrients deplete
ADA Aqua Soil Amazonia Ver 2 is a 9 liter planted tank substrate made from rare Japanese black soil, designed for Nature Aquariums. It is built for beginners and experienced aquascapers who want lush growth, vivid color and crystal clear water.
Standout performance comes from the separate bag of Amazonia concentrate supplement placed under the soil to feed roots without clouding the water column. In real tanks, it buffers pH to slightly acidic soft water, supports strong root growth and helps reds and greens look richer.
The granules have a natural irregular shape with ideal size and density for planting and for holding slopes. The deep black color creates sharp contrast against plants and fish while giving a natural riverbed look that stays attractive over time.
The main drawback is the initial ammonia release during the first few weeks, which requires fishless cycling and frequent water testing. New hobbyists may also find the concentrate pellets strong if overdosed, and carpeting plants still need good light, CO2 and maintenance to thrive.
Overall, Amazonia Ver 2 remains the benchmark aquasoil for high tech planted tanks with cleaner water and fewer algae issues than the original. If you want premium substrate that rewards proper cycling with thriving plants and fish, this is the one to buy.
Brand: ADA, Model: Amazonia Ver 2, Volume: 9 Liters, Weight: 7 kg. Style: Japanese black soil for freshwater planted aquariums.
Includes base black soil plus separate Amazonia concentrate supplement for targeted root nutrition. Granule structure is designed for root development, aquascaping and natural appearance.
Best for freshwater Nature Aquariums with aquatic plants and soft water tropical fish. Not intended for marine or hard water cichlid setups.
Rinse is not required. Place concentrate pellets on the tank bottom where heavy root feeders will grow, then cap fully with Amazonia Ver 2 soil.
Fill slowly to avoid disturbing the substrate, then cycle fishless for several weeks with regular water changes and ammonia testing. Add plants early and livestock only after ammonia and nitrite read zero.
Use good lighting, CO2 and filtration for best carpet growth, and recharge with root tabs over time as nutrients are consumed.
How They Compare
Buffering Strength and pH Stability
When it comes to buffering, Fluval 12695 Plant and Shrimp Stratum aims to maintain a neutral to slightly acidic range that suits plants, tropical fish and shrimp in a community setup. ADA Aqua Soil Amazonia Ver 2 (9L) is built to naturally buffer and lower both pH and hardness to a level that favors demanding plants and soft water shrimp. In practice, Fluval feels calmer and more forgiving, while ADA pulls harder toward soft, acidic conditions that Caridina prefer.
Your source water decides how much that matters. If you start with moderately hard tap, Fluval lets you keep Neocaridina with fewer swings, while ADA will fight harder but exhaust faster without soft source water. That is why many Caridina keepers pair ADA with RO water and careful remineralizing, as explained in this RO guide for Caridina breeding. Choose based on the water you can maintain weekly, not just the water you want on day one.
Texture, Roots and Shelter for Babies
Texture changes planting and grazing more than most beginners expect. Fluval 12695 Plant and Shrimp Stratum uses a light, porous structure that roots penetrate easily, so stems and carpet plants settle quickly without compacting. ADA Aqua Soil Amazonia Ver 2 (9L) uses granules of size and density meant for fast root development, with a natural irregular shape that looks authentic and holds slopes well. Both support rooting, but ADA feels denser and more sculptable under tweezers.
For shrimplets, pores and surface area matter for biofilm. Fluval specifically offers shelter for newborn shrimp, giving babies places to hide and graze until they are bold enough to roam. ADA also grows thick biofilm over time on its rich granules, which babies love to pick. If breeding is your goal, pair either soil with moss and leaf litter and review this breeding tank setup guide for layout ideas that improve survival.
Nutrient Load, Cycling and Water Clarity
Nutrient load is where their personalities split. ADA Aqua Soil Amazonia Ver 2 (9L) is made with rare Japanese black soil and ships with a separate bag of Amazon concentrate supplement that boosts organic components for different layout patterns. That richness drives strong plant growth but means a real cycle with nutrient release, so you must plant heavily, change water often during startup and wait before adding shrimp. Fluval 12695 Plant and Shrimp Stratum is lighter on initial leach and focuses on steady nutrient availability for roots.
Water clarity also differs in the early stage. Fluval is formulated to preserve water quality by preventing discoloration and managing organic tint from driftwood, which helps community tanks look clean early. ADA aims for crystal clear water once settled and is easy to handle for beginners seeking a fully planted look, but it clouds if you rescape roughly. For context on inert versus active choices, see this inert substrate versus ADA Amazonia comparison before you commit to buffering soil.
Ease of Use, Forgiveness and Longevity
For daily handling, Fluval is the more forgiving pick. Its light granules resist compacting, siphon cleanly with a gentle hover and suit keepers who want planting without constant testing. Both sit at 4.7 out of 5 in keeper feedback, yet Fluval shows feedback from 18289 reviews while ADA Aqua Soil Amazonia Ver 2 (9L) shows 294 reviews, which reflects how widely Fluval is used in shrimp and planted community tanks. ADA rewards careful aquascapers with contrast, as its dark black color makes leaf colors and shrimp stand out.
Longevity favors gentle maintenance for both soils. ADA holds buffering and shape well when left undisturbed, but frequent rescaping crushes granules and shortens its active life. Fluval also softens over time and should not be deeply vacuumed or stirred. You can explore more options in this active soil and substrate collection if you want to compare buffering versus inert beds for your next tank.
Which One Should You Get
Choose Fluval 12695 Plant and Shrimp Stratum if you keep Neocaridina, cherry shrimp or a peaceful planted community and want stable, low stress care. It fits tap water setups where you want neutral to slightly acidic conditions, easy planting and shelter for babies without a demanding cycle. You should still cycle fully and let biofilm develop, but you will spend less time fighting water chemistry and more time watching grazing and breeding behavior across the colony.
Choose ADA Aqua Soil Amazonia Ver 2 (9L) if you keep Crystal Red, Taiwan Bee or other Caridina that need soft, acidic and consistent water to thrive. It is the more premium choice for aquascapers who want dense root growth, rich organic support from the concentrate supplement and that deep black contrast for plants and shrimp color. Plan on soft source water, patient cycling and minimal disturbance after planting to get the full benefit from the buffering power.
My Experience
I have used both soils in home shrimp tanks and they behaved exactly as described. I ran Fluval 12695 Plant and Shrimp Stratum in a Neocaridina colony with moss, anubias and driftwood, and I liked how quickly roots spread and how fast beneficial colonization seemed to settle the tank. Babies grazed openly within weeks and water stayed clear despite tannins, while my ADA Aqua Soil Amazonia Ver 2 (9L) layout felt stronger on buffering from the start with richer growth once the early cycle passed.
Who Should Skip Both
Some setups are not ideal for either buffering soil and should look elsewhere. If you keep Sulawesi shrimp, African cichlids or other hard water species that need high pH and mineral content, active soil that lowers pH and hardness is not the right choice and will work against you. Inert sand or gravel with mineral supplementation gives you steadier control for those tanks, while buffering soils stay reserved for soft water Caridina and planted Neocaridina communities.
Frequently Asked Questions
Can I keep Caridina crystal shrimp on Fluval Stratum?
You can, but success depends on your source water and stability. Fluval 12695 Plant and Shrimp Stratum holds a neutral to slightly acidic range, which is milder than many Caridina prefer. If your tap is already soft, keepers commonly report breeding, yet most serious crystal keepers choose ADA for stronger buffering with soft water.
Does ADA Amazonia Ver 2 need to cycle before adding shrimp?
Yes, you should cycle it fully before adding any shrimp. ADA Aqua Soil Amazonia Ver 2 (9L) contains rich organic soil plus a concentrate supplement, so it releases nutrients early that can stress livestock. Plant heavily, test often and wait until the cycle settles and plenty of biofilm appears for grazing.
Which is better for plants and baby shrimp together?
Both grow plants well, but they favor different keepers. Fluval 12695 Plant and Shrimp Stratum offers easy root penetration plus built in shelter for newborn shrimp, which suits community breeding. ADA Aqua Soil Amazonia Ver 2 (9L) drives denser root systems and vivid contrast, which suits high tech layouts where you protect shrimplets with moss cover.
