Cycling & water balance
Nitrogen conversion, oxygen, alkalinity, pH, solids handling and feed-to-plant balance.
Balance fish feed and planted area
Turn feed grams per day into a transparent area comparison, then check the biological and hydraulic limits.
Interactive tool · 6 min + guided practice →Cycling & water balanceFishless cycling: prove the biofilter works
Establish nitrification with a known input and repeated measurements before stocking.
6 min + guided practice →Cycling & water balanceWater quality: pH, ammonia and alkalinity
Track the interacting measurements that govern fish, roots and nitrification.
Interactive tool · 6 min + guided practice →Cycling & water balanceSolids removal and biological filtration
Separate particle collection from dissolved nitrogen conversion and design maintenance access into both.

Buy measurements you can interpret. Match the test range, reporting basis, calibration and replacement supplies to the questions a fish-and-plant system needs answered.

A vessel that catches particles and a surface that supports nitrification solve different problems. Compare their loading assumptions, service access and evidence before buying.

Read total ammonia with temperature, pH and its reporting basis. Restore failed system functions, reduce the immediate load and document a response before making chemical changes.
