Water purification: purity, prices and refused pitchers

Read the composition, not just the label

Wikily defines purity as water divided by all liquid in the container. Mineral, Chlorine and Alcohol all reduce that share, even when they were added for another useful purpose. Its Pure Water threshold is 99.9%; High-Quality Water begins at 99%, and Basewater at 98%. Check the composition before promising a grade to a customer.

Budget with the patched prices

The official 1.0.0.2 notes rework Water Purifier logic and reduce Moisture Farm from 650 to 350 and Water Filter from 50 to 25. The Water Purifier price reduction actually appears in 1.0.0.5, from 300 to 250. Do not budget from the earlier machine price or assume that an old purification walkthrough still matches the revised logic.

Remove the filter before offering the pitcher

In 1.0.0.5, customers explicitly tell you to remove the Water Filter when it is still inside an offered Water Pitcher. Previously they refused silently. Treat that message as a container setup problem first, not proof that the entire batch is unusable. Removing the filter addresses this refusal condition; it does not itself prove the water meets a higher purity grade.

Separate water value from container value

Wikily lists Basewater at 40 Credits per liter and Pure Water at 80. Its example gives 750 mL of Basewater a water value of 30, then adds 5 for the bottle, totaling 35 before markups. These are community reference values, not our playtest. Account for the container separately when judging a batch’s value.

Purify overnight, then test and match the label

For an ordinary water batch, put its container in the Water Purifier and allow overnight processing with 4 kJ available. Wikily says it processes one container per night, with each step taking a night. Without Quality modules, ordinary water plateaus at 99.26%, High-Quality Water; repeating nights alone does not remove that limit. Quality 100 enables Pure Water. Check progress rather than assuming a dirty input finishes in a single night.

Test the result with a single-use Water Testing Strip or reusable AquaScan and verify at least 99.9% before treating it as Pure Water. Use Match label on your own container to align the label with the tested grade. A Water Filter catches specified contaminants but does not catch or kill Microbes, so filtering alone is not proof of microbiological cleanliness. These steps and limits follow Wikily, not an independent playtest.

Match the tool to the contaminant

Wikily’s tool list gives a practical distinction: a Water Filter catches Organic Waste, Microplastic, Physical Contaminant and Mineral, while a reusable UV Lamp converts Microbes to water immediately. A Purification Tablet adds 15 mL of Chlorine, reduces Chemical Contaminant to 0.7%, then kills Microbes. Chlorine remains part of the liquid composition, so successful disinfection alone does not establish Pure Water.

For a quick Basewater target, Wikily lists the HydraTech Micro Water Purifier as an immediate treatment with 300 durability, spending 1 per 100 mL. It does not promise Pure Water. Choose it for that documented target, or use the overnight purifier route above for higher purity, then test the result and match your own label.

Aquaculture: keep the tank alive overnight

For fish, water volume is a separate survival check from drinking-water grade. Wikily’s RAS tank holds 12000 mL. Adult Tilapia types need 750 mL each, Eel and Electric Eel 1200 mL each, and Sturgeon 3000 mL each. Below half the combined requirement, all fish die; a shortage above that still costs health. Fish outside a RAS tank at night die. Total the needs of your actual stock before adding fish, rather than assuming a partly filled tank is sufficient.

Wikily says Organic Waste at 3% of tank volume starts harming fish and 8% kills them; Graft Tilapia is twice as sensitive, while Gutter Tilapia takes no waste damage. RAS filters clean on powered nights. Feed before assuming a water fix solves everything: Tilapia are omnivores, while Eel, Electric Eel and Sturgeon eat meat. Hungry fish can eat roe and fry, so breeding stock also needs reliable feeding. This section covers water and feeding failures, not every fish recipe or breeding setup.
