The use of a calcium reactor can therefore be dispensed with. When used correctly, the Grotech Balling System covers the needs of your saltwater aquarium for the macro-elements carbonate, calcium and magnesium. This is ideally around 380-450mg / lĪpplication of the balling system with Grotech carbonate, calcium, mineral and magnesium pro instant. When using Calcium pro instant in the aquarium, the calcium content of the aquarium water should be checked regularly. Pour directly into the filter basin in an area with good flow. In the case of larger deviations, an increase should be made over several days. 24 mg / l per 100 liters of aquarium water. 6.5 g) increases the calcium content by approx. Please use a suitable plastic container.ġ measuring spoon (approx. 10 mg per 100 liters of aquarium water.ĭissolving causes high temperatures. This solution then contains 135,000 mg / liter calcium (Ca).Īdding 7.4 ml of this stock solution increases the Ca content by approx. Put 750g calcium pro instant in a measuring cup and fill up to 2000ml with osmosis water. The Balling stock solutions of carbonate, calcium, magnesium and mineral pro instant must be dosed separately in equal parts! Put 54 g calcium per instant in a measuring cup and fill it up to 1000ml with osmosis water. It can either be used to prepare a stock solution or added directly to the aquarium. The request could be served because the application has reached its usage limit.Īn error has occorred in the server which has not been properly handled.Large amounts of calcium and magnesium are required in the saltwater aquarium.Ĭalcium pro instant is a ready-to-use calcium mix. The following kinds of errors can be returned by the API: HTTPĪuthentication credentials were missing or authentication failed. If the call was not successful, this fields will contain a detailed text message. The time (in milliseconds) taken to serve the request The authentication parameter sent out by the client (the wskey parameter)Ī boolean (true/false) flag denoting the successful execution of the call The following table shows the fields appearing within an error response: Field The XML output is primarily based on RDF/XML format for RDF serialization but following the EDM XSD schema (the same schema is also used for data ingestion to Europeana).Īn error occurring during processing of an API method is reported by (1) a relevant HTTP status code, (2) a value of the success field and (3) a meaningful error message in the error field. The schema is further explained in the next Section.Īn alternative JSON output based on the JSON-LD format for RDF. The output serialized in JSON and using a Europeana specific schema for representing EDM data. The table below explains each of the formats and the respective extension. To request a record in either of these formats, just alter the extension of the call to the desired format. Both JSON-LD and RDF/XML are formats to represent Linked Data which used predefined transport schemas for serializing RDF data. The primary and default output supported by this API is JSON which also means that some fields are only available in this format. The Record API supports 3 serialization formats, namely: JSON, JSON-LD and RDF/XML. See next section on Output FormatsĪdditional parameters may apply to the request above such as the API key and Browser access. The file extension corresponding to one of the supported output formats, namely. The identifier of the record which is composed of the dataset identifier plus a local identifier within the dataset in the form of "/DATASET_ID/LOCAL_ID", for more detail see Europeana ID. Where the variables in the URL path mean: RECORD_ID Every call to the Record API is an HTTPS request in the following URL signature.
