How we produce the Frescalo Service Guides

Last reviewed: November 15, 2026

Frescalo is software built for the firms that look after their clients’ aquariums, the water systems behind living walls, and koi and ornamental fish ponds. The Frescalo Service Guides are written for the owners of those firms and the people who work in them: winning clients and pricing the work; the agreements behind it and getting paid; the service visit, the breakdown and the seasons; and the species, import and water-hygiene rules that reach the systems they look after.

Where the guides come from

We research each guide from primary sources: the laws, regulations and official lists that govern which fish, corals, invertebrates and plants may be kept, moved or brought in, the water-hygiene rules that cover misting and water systems in buildings, the published guidance and forms of the agencies that run them, public tenders and official statistics. We name each source where we use it and list it at the end of the guide, so you can check it yourself. When a source says “should”, we write “should”; a proposed rule is called proposed; guidance is called guidance; and a rule that no longer applies is said to no longer apply.

Examples and worked records

Most guides follow an example: the owner of a care firm, a client and a record, put together to show how a decision works. Unless a guide says it is about a real person who agreed to be named, that owner is not a real person, and the guide says so in its second paragraph, in words such as “Maya is not a real person. She, the hotel and its record are an example built for this guide.” In a worked record, the column that holds the example’s entries is headed “(example)”, and the readings, dates and prices in it belong to the example. A figure that comes from a source is named with that source.

When an example follows one place’s rule, the guide says so early, says whose rule it is, and reminds you that a system somewhere else follows its own rule. Reading a guide in another language does not make its rule apply where you work.

How they are written

We use AI tools to help research and draft the guides. Before a guide goes live, we read it aloud, check every claim against its source and every figure against its table, and check it against our publishing standards.

We write each language edition for its own readers, with local units, currency, trade words and examples. We do not translate guides word for word.

Frescalo Editorial is the publisher byline for the guides. Where a named person has reviewed a guide, the guide says so.

Dates and updates

Every guide shows the date we published it. When we change a guide substantially, for example because a species list, a permit, a form or a water-hygiene rule has changed, we also show the date of that update. Guides that depend on rules or prices carry a review date, so we know when to check them again.

Corrections

If a figure is wrong, a rule has changed or you think we have missed something, write to support@frescalo.com. We read every report and correct guides when they need it.

What the guides are not

The guides are general information for the firms that look after aquariums, living walls and koi ponds. They are not legal, veterinary, tax or financial advice. They never give a dose, a treatment or a diagnosis for a fish, coral, invertebrate or plant, and never set a reading as an ideal or a target: each firm sets its own ranges, and a qualified person, such as a veterinarian who treats fish, decides on treatment. They give no electrical, plumbing or backflow instructions: that work follows the rules where you work and the qualified people who carry it out. They do not replace advice from a qualified professional or from the authority responsible for the systems you look after.

Frescalo keeps the record of what your team checked, measured, changed and reported at each visit, against the ranges you set. Living systems carry inherent biological risk; Frescalo documents care – it does not guarantee outcomes.

Species, import and water-hygiene rules differ from one country, state, province and city to another, and they change. The duties those rules set sit with the people they name: water-hygiene duties usually sit with the building’s owner or whoever is in control of the premises, and species and import rules bind whoever keeps, moves, sells or releases the animal or plant, which can be the care firm when it restocks, empties or moves a system. Owners and care firms remain responsible for meeting the rules that apply where they work. Check the official sources we link before you act, and take professional advice where you need it.

We take reasonable care to keep the guides accurate, but we cannot guarantee that every guide is complete, error-free or current in every circumstance. To the fullest extent permitted by law, Frescalo is not liable for loss arising from reliance on the guides. Links to other websites are for reference, and we do not control those sites.
