where to buy this product

About this product

  • Due to its high porosity, it supports nitrifying bacteria to break down toxic substances such as ammonia and nitrite
  • It's a 100% natural filter material that does not require replacement, and can be used indefinitely
  • It's colonized by beneficial bacteria regardless of the type of water that requires filtration: fresh water or salt water
  • The shape of FilterMAX allows the entire volume of the filter to be used, but without affecting the water flow
  • The 6-12 mm size of the filter media makes FilterMAX compatible with any filter system
  • Because the beneficial bacteria colonize the internal pores, after cleaning the filter, the risk of destabilizing the aquarium is non-existent
  • 1 liter of FilterMAX is more than enough for a 100 liter aquarium
  • Before the first use, rinse with water to remove the fine dust from the filter media
  • The ideal placement of FilterMAX in your filter is immediately after the mechanical filtration
  • For the fastest FilterMAX cycling, squeeze an already colonized with bacteria sponge into the aquarium and let the filter absorb them
  • In the event of a reset, do not leave the filter off for more than 5-6 hours to prevent the loss of bacteria
  • Keep filter media clean by cleaning the external filter every 3-6 months
  • If denitrification occurs in your system and the NO3 values are close to zero, clean the filter more often

Kevin Hoehlein

I have tried many fertilizer systems and many worked well. However, I was never completely satisfied with the densely planted aquariums and the demanding plants. MasterLine made possible what other fertilizers could not.

MasterLine is the fertilizer used in our family for over 4 years. It gives us the joy of growing beautiful and healthy plants from those with easy requirements to those with a high degree of difficulty, without problems. It's an easy fertilizer system to be used by both beginners and experienced aquarists.
