Our speciality

Premium RODI water

Reverse osmosis followed by deionisation, polished to 0 ppm TDS. Nitrate and phosphate free, with nothing added and nothing left behind. Use it for top-off, or mix your own salt.

Feed your corals, not your algae

Both our RODI and our saltwater are nitrate and phosphate free, so every top-off and water change feeds your corals, not nuisance algae. We start with pure water and one trusted salt, and make every batch the same way.

0 ppm

A pure starting point

Every drop goes through RO membranes and DI resin, and resin is changed before TDS can creep up. No nitrate or phosphate going into your tank.

1 salt

Instant Ocean, every batch

One proven salt, mixed to the same salinity every time. Your parameters won't swing from one water change to the next.

At the door

You see the reading

We test in front of you before we pump: TDS on the RODI, salinity on the saltwater. No pollutants, no hitchhikers, no guesswork.

Good to know

What containers do I need?

Clean, food-grade 25 L containers, one per fill. Keep RODI and saltwater containers separate.

When will you arrive?

You choose the day when you book: we deliver Monday to Friday, never at weekends, on bank holidays (including the whole Easter weekend), from 24 to 26 December, or on New Year's Eve and New Year's Day. Order by 6pm the day before. We text you a time window the evening before.

When do you start delivering?

We're launching in Essex late October / early November 2026. Register your interest for water deliveries below and we'll email you as soon as you can book your first delivery.

Is there a minimum order?

Yes, £35.97, which is three saltwater fills. Smaller orders include a top-up to reach the minimum, shown before you pay.

Will your water feed algae in my tank?

No. Both our RODI and our saltwater are nitrate and phosphate free, the two nutrients that fuel nuisance algae. Feed your corals, not your algae.

Why synthetic saltwater rather than natural?

Consistency. Every batch starts at 0 ppm TDS and is mixed with the same salt to the same salinity, so there are no seasonal swings, pollutants or unwanted organisms.

When are you coming to Kent and Hertfordshire?

Soon. Register your interest below with your postcode and we'll let you know first.
