1. Waterblocs

A Natural Biological Treatment for Ponds, Lakes, Dams and Aquariums.

Waterblocs are a specially formulated porous mineral substrate containing multiple nutrients to promote the rapid growth of beneficial bacteria when immersed in aquatic water systems.

Waterblocs are suitable for water systems where fish, turtles, plants, pets and other organisms live. However Waterblocs have not been certified for water that will be used for Human consumption.

Colonies of naturally occurring beneficial bacteria produce enzymes that consume organic waste, ammonia and unwanted nutrients that cause cloudy water that can deplete oxygen levels essential for aquatic life in a well balanced ecosystem. They will reduce the frequency of water changes in fish farms and aquariums. Ponds and lakes are dosed at the start of each season.

  • Biodegradable porous mineral substrate with ZEOLITE*
  • Helps prevent oxygen depletion and precipitate organic matter
  • Contains multiple organic and mineral nutrients for bacterial colonies
  • Promotes rapid growth of naturally occurring beneficial bacteria
  • Stimulates anaerobic bacteria growth for sludge reduction
  • Promotes aerobic bacteria to consume excessive nutrients
  • Buffers pH and adsorbs ammonia and dissolved heavy metals
  • Suitable in salt or fresh water for all fish, plants and organisms
  • Flotation & Netting System

Water bodies clogged with decaying organic matter and sludge become oxygen depleted creating a toxic bottom layer of stagnant water unsuitable for fish and aquatic organisms. Waterblocs TM contain *ZEOLITE that has a unique atomic microcellular structure to increase internal substrate surface area and chemically adsorb ammonia and natural trace elements providing additional nutrients for colonies of beneficial bacteria that restore water balance. Waterblocs do not support combustion and have a long storage life.

Depending on where Waterblocs are suspended within a water column they will encourage the growth of a broad spectrum of aerobic bacteria in upper surface layers and in the absence of oxygen, anaerobic bacteria in fish toxic lower regions. Enzymes produced reduce sludge without undesirable by-products including smelly hydrogen sulphide and methane gases.For International
