Why Filter Your Water First

Municipal tap water is treated for people, not fish — it carries chlorine or chloramine, plus nitrate, phosphate, silicate, and hardness minerals that algae love and delicate species don't tolerate. Filtering it to a clean baseline removes a whole class of problems before they start.

How the Stages Work

• Sediment prefilter — traps grit and particulates that would clog what follows.
• Carbon prefilter — strips chlorine and chloramine that would otherwise damage the membrane.
• RO membrane — the core stage, rejecting the vast majority of dissolved solids.
• DI resin — a final polish that drives total dissolved solids to zero.
• Meters and fittings — TDS pens, tubing, valves, and adapters to run and monitor the unit.

Replace prefilters and resin on schedule, and let a TDS meter tell you when — a climbing number means a stage is spent. Whether you mix salt, top off, or fill a planted tank, clean water in makes everything downstream easier. Questions on choosing a system? Email info@jlaquatics.com.
