NT Labs Nitrate Aquarium & Pond Water Testing Kit (30 Tests)
【 MONITORS NITRATE IN AQUARIUM AND POND WATER】: Nitrate is produced by the beneficial bacteria in the water and filters as they break down the fish’s toxic waste products (ammonia and nitrite). Nitrate is not typically toxic to fish, but excessively high levels (>100mg/l) can cause problems with growth.
NT Labs Phosphate Aquarium & Pond Water Testing Kit (40 Tests)
【 MONITORS PHOSPHATE IN AQUARIUM AND POND WATER】: Phosphate is a major nutrient found principally in fish food to help with growth, good bone formation and many other biological processes. However, not all of the phosphate will be utilised by the fish and will be excreted as a waste product. It can also be generated by the breakdown of other organic matter and is also often present in tap water. While phosphate is beneficial for life, it is only required in small quantities. Increased phosphate in the water column is often a major contributor to the growth of nuisance algae. At low levels, it is generally considered safe for fish, but should be monitored for algae prevention.
