Product description:

Rock suitable as a filter medium to SUMPA, to build a reef in reef and decoration in Tanganika / Malawi aquariums. There are in many sizes from small rocks about 10cm to larger 20-40cm.



Recommendation:

If the coral rock is used as a basic filtration medium, 0.5-0.7 kg of rocks for every 4 liters of water should be used. If the rock is not the main filter medium, you can use any amount of rocks until a satisfactory visual effect is obtained. We do not recommend adding our rock or any other to the stabilized marine aquarium without prior testing. The rock we offer is 100% free of organic and hardener which makes it safe for the system stabilized without fear of the ammonia jump.



How to change the dry rock in the biologically active rock?

To start the biological filtration of the rock must be activated through bacterial strains. It's best to use Liquid Brightwell Aquatics Microbacter7 or Azoo Nitripro Marine. You can also put some sand and rocks from the already functioning aquarium. At this time, ammonia, nitrites and nitrates should be prompted. When ammonia and nitrites reach 0 or close zero can be considered that the rock is already active biologically.
