What are Bio Blocks?
Bio Blocks are ultra-porous ceramic filtration media designed to provide extremely high surface area for beneficial bacteria in aquarium and pond systems.
How do Bio Blocks improve filtration?
They provide both aerobic and anaerobic zones that allow beneficial bacteria to efficiently process waste and stabilize water quality.
What makes Bio Blocks different from other media?
They offer exceptionally high usable surface area, with tens of thousands of square feet per liter, allowing more efficient filtration in less space.
What waste do Bio Blocks help reduce?
When properly colonized, they help reduce ammonia and nitrite to near zero while also lowering phosphate and dissolved organics.
Can Bio Blocks be used as the only filtration media?
Yes, they can function as a primary biological filtration media or be used alongside other filtration types.
What types of aquariums can Bio Blocks be used in?
They are designed for marine and hard freshwater aquariums, typically with a pH of 7.5 or higher.
How do Bio Blocks support beneficial bacteria?
Their internal pore structure provides extensive colonization space, allowing bacteria to convert harmful waste into less toxic compounds.
Do Bio Blocks help stabilize pH?
Yes, they are infused with aragonite, which helps buffer pH at the bacterial level and supports long-term filtration efficiency.
How much Bio Block media should I use?
Use one 1.5 inch block per 20 to 40 gallons or one 2 inch block per 30 to 50 gallons, adjusting for higher bioloads.
Should Bio Blocks be rinsed before use?
Yes, rinse with aquarium or purified water to remove dust before placing them in the system.
Can Bio Blocks be seeded with bacteria?
Yes, soaking them with a compatible bacterial supplement before use helps accelerate colonization and filtration performance.
Is pre-seeding required?
No, but it significantly speeds up the establishment of biological filtration.
Where should Bio Blocks be placed?
They should be placed in areas of good water flow and oxygenation to maximize nitrification efficiency.
Should mechanical filtration be used with Bio Blocks?
Yes, using filter floss or sponges before the media helps prevent clogging and maintains long-term performance.
Can I use a carbon source with Bio Blocks?
Yes, providing a carbon source can enhance bacterial growth and improve nutrient processing efficiency.
Do Bio Blocks require maintenance?
They require minimal maintenance but should be protected from debris buildup to maintain effectiveness.
Can Bio Blocks be used in high bioload systems?
Yes, their high surface area makes them suitable for heavily stocked aquariums and ponds.
Can Bio Blocks be used during aquarium startup?
Yes, they can be used during initial setup to help establish biological filtration more quickly.
What results can I expect from using Bio Blocks?
Improved water clarity, reduced toxic waste, and a more stable and efficient biological filtration system.
