Salt mix and RO/DI guide

Salt mix and RO/DI water checklist for Florida reef owners.

Florida's heat, humidity, and hurricane season make water supply planning more important than in other regions. Keep enough salt and purified water on hand so a power outage, equipment failure, or missed delivery doesn't leave your livestock at risk.

What to keep stocked

The goal is simple: never be caught without water-change capacity. One unplanned emergency, storm, or delivery delay can exhaust your supply fast.

Salt mix — keep 1–2 bags of your regular brand on hand for water changes and emergencies

Confirm quantities with your current water-change schedule, then store enough for at least two full water changes beyond your regular routine.

RO/DI system with fresh membranes and resin; check TDS before every batch

Confirm quantities with your current water-change schedule, then store enough for at least two full water changes beyond your regular routine.

Mixing vessel, powerhead or pump, and submersible heater for pre-mixing saltwater

Confirm quantities with your current water-change schedule, then store enough for at least two full water changes beyond your regular routine.

Refractometer or digital salinity meter calibrated against a reference solution

Confirm quantities with your current water-change schedule, then store enough for at least two full water changes beyond your regular routine.

Dedicated storage containers for pre-made saltwater and RO/DI reserve

Confirm quantities with your current water-change schedule, then store enough for at least two full water changes beyond your regular routine.

Florida-specific considerations

Saltwater reef owners in Florida face specific supply-chain pressures that hobbyists in other states may not deal with as often.

Hurricane and storm prep

Stock enough salt and RO/DI water before storm season so a week-long delivery gap or power outage doesn't interrupt water-change capacity.

Evaporation and top-off demand

Florida heat accelerates evaporation. Size your RO/DI production and storage capacity to your actual top-off consumption, not just your water-change schedule.

RO/DI membrane life in Florida tap water

Florida municipal water quality varies by region and season. Test TDS regularly and replace membranes and resin before output quality drops.

When to call a local pro

If a water-quality issue is causing coral recession, fish stress, or parameter swings you can't stabilize, escalate to a local reef maintenance provider before livestock is lost.
