PO4 MARINE WATER TEST KIT
Prevent problematic algae growth:
Nitrates and phosphates are vital nutrients for algae. With the Colom-
boNitrate and Phosphate test kits the nitrate and phosphate levels can
be determined easily.
Fish excrete the toxic ammonia, which is converted into
nitrate by beneficial bacteria. Phosphates are released from fish food.
As a guide you can say: The more fish you keep, the larger the production
of nitrates and phosphates. By keeping the nitrate and phosphate levels
at the optimal values algae growth is greatly reduced
Colombo have produced test kits that are developed especially for
seawater. These tests give the best results!
