About Nexmivex
Nexmivex.eu is a reference covering freshwater aquarium care — tank cycling, water parameters, plant selection, and species compatibility — written for hobbyists keeping fish in Poland.
What this resource covers
Articles focus on the practical side of freshwater fishkeeping: choosing the right filtration for tank volume, understanding nitrogen cycling, interpreting water test results, and selecting plant species that match the lighting available in a given setup.
Who maintains it
The content is maintained by a small editorial team with backgrounds in biology and long-term freshwater hobbyist experience. Articles are reviewed periodically and updated when new data or commonly reported errors are found.
Approach to accuracy
Where specific parameters are cited — pH ranges, temperature tolerances, CO2 concentrations — these are cross-referenced with published fishkeeping literature and peer-reviewed aquatic biology sources. Uncertainty is stated where it exists.
Scope and limits
This resource focuses on freshwater aquariums. Saltwater and brackish setups are outside the current scope. The content reflects conditions and product availability relevant to the Polish market but most information applies broadly.
