AquaEco SeaPrep
No big mixing barrel. Load salt once. Make seawater on demand.
SeaPrep stores dry salt and prepares a measured batch of seawater when you ask for one. Every batch is dosed, mixed, measured and corrected before it leaves the machine.
Per batch
What happens when you ask for seawater
Intake
Purified water enters through the built-in RO/DI stage.
Dose
Salt is dosed from the dry load, by the profile for the salt you are using.
Mix
The batch is mixed in the working chamber.
Measure
Salinity is read at the outlet, temperature compensated.
Correct
Out of band, the loop corrects and measures again.
Release
Only an accepted batch is released.
Two sizes
One system, two working volumes
Both store dry salt and prepare on demand. The difference is how big one batch is.

Why it is different
What we will and will not claim
- A named salt list
We publish which salts we have run, and how many complete batches each has been through. We do not claim compatibility with every salt.
- Figures with their conditions
Every published number says what it was measured under. Anything still in validation says so where it is shown.
- A stated shipping window
Every order is tied to a production batch and a window. If the window moves, the site changes.
Compatibility
The salts we have run
Verified means at least three complete batches. Salts under test and salts customers have asked for are listed with their state.
