Sera Biotope Asia, Manual

Page: 15 / 17

Possible causes for measured nitrite and nitrate values
above the stated maximum values are:
• too many fish
• too few plants
• insufficient and/or biologically inactive filter capacity
• overfeeding
Immediate help:
First test the water, then – depending on the values – add 5 ml
# toxivec per each 20 liters. Carry out water check. Finally
increase or lower the water values as described in the chart.

pH Test
Instructions for use:
1. Clean vials thoroughly before and after each test.
Shake the liquid reagents before using. Close
reagent bottles firmly, immediately after use.
Do not switch bottle caps.
2. Rinse vial several times with the water to be
checked. Fill to the 5 ml mark and dry the exterior.
3. Add 4 drops of the reagent and shake gently. Place
vial on the white area of the color scale, and look
from above to determine the pH value according to
the color. We recommend comparing colors in
daylight as artificial light makes it difficult to
distinguish colors.
