Inaccurate calculations when mixing RO and tap water

Problem: Final parameters don't match calculated ones

Solution:

• Check that tap water parameters are up to date
• Ensure quality of RO water (TDS < 10)
• Account for seasonal changes in tap water composition
• Check test with calibration solution

"Testing water" option shows incorrect results

Reason: Current or target parameters entered incorrectly

Solution:

• Ensure accuracy of current GH/KH measurements
• Check that target values are realistic
• Use calibrated tests for initial measurements

Calculation doesn't work for non-standard water preparation schemes

Problem: System cannot process complex water source combinations

Solution:

• Use "Other" mode for complex schemes
• Break the task into simpler stages
• Calculate each mixture component step by step
