Self-diagnose

How to test your water

Confirm for yourself whether dissolved organic carbon is building up in your system — and understand what your result means for fish health and FCR.

Why test for DOC?

The symptoms you see in your fish — poor growth, eroded fins, gill mucus, off-flavour — are downstream of dissolved organic carbon and phenols accumulating in the water. Testing your water for DOC tells you whether this is what’s holding your system back. If your DOC is elevated, CarbonClear is directly relevant to you.
