I know the PH is dropping now to below 10, but as I do not want to make extra stress for the bacteria, I am not raising it for a while and see how long it can sustain this situation. On October 15th, I started to add 15g of calk to raise it a bit, but not very drastically. <\/p>\n<!-- \/wp:paragraph -->","_en_post_name":"coldness-and-fermentation","_en_post_excerpt":"","_en_post_title":"Coldness and Fermentation","_de_post_content":"","_de_post_name":"","_de_post_excerpt":"","_de_post_title":"","edit_language":"de","neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":""},"categories":[9,8],"tags":[],"_links":{"self":[{"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/posts\/1848"}],"collection":[{"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/comments?post=1848"}],"version-history":[{"count":2,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/posts\/1848\/revisions"}],"predecessor-version":[{"id":1883,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/posts\/1848\/revisions\/1883"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/media\/1852"}],"wp:attachment":[{"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/media?parent=1848"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/categories?post=1848"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nerding.at\/circular_blue\/de\/wp-json\/wp\/v2\/tags?post=1848"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
