In many cases too low a calcium concentration retards coral and coralline algae growth. Calcium also fulfils many important biological functions. In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion. To maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg/L from the optimum range of 420 - 450 mg/L so regular testing should be carried out. This means that any calcium test used should have an accuracy of significantly less than 15mg/L otherwise it will be difficult to monitor such fluctuations. The Salifert test kit measures in steps of 5 mg/L and has an accuracy of 10 mg/L. The colour change is precise, detecting small but significant fluctuations in the concentration of calcium. The test is not affected by magnesium. Saliferts Coral Calcium additive is a highly concentrated additive which makes calcium addition easy. Sufficient for at least 50 tests","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/g3socunzgxk_8fb7b476-efea-4767-9fab-2e63996364f3.jpg?v=1789379968","href":"/product/salifert-calcium-profi-test-kit-5187-40739.html","buy_url":"https://xyjpsn-3p.myshopify.com/products/salifert-calcium-profi-test-kit-5187-40739","buy_url_source":"shops.shop_domain + product.handle","seller_name":"xyjpsn-3p.myshopify.com","seller_url":"https://xyjpsn-3p.myshopify.com/","return_policy_url":"https://xyjpsn-3p.myshopify.com/policies/refund-policy","media":[{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/g3socunzgxk_8fb7b476-efea-4767-9fab-2e63996364f3.jpg?v=1789379968","alt":null,"position":0}],"related":[{"handle":"moq-6kg-pla-2-0-upgraded-pla-pla-plus-3d-printer-filament-1kg","title":"[Min. 6 bobine] PLA+ 2.0, PLA+ Aggiornato (PLA Plus), Filamento per Stampante 3D 1 kg","category":"Filaments","price":"$11.09","image_url":"https://cdn.shopify.com/s/files/1/0704/0027/8683/files/PLAV2_RF_GY.jpg?v=1757900977","sku":"DLZ-EU-SL-PLA+V2-GY-RF-1KG","href":"/product/moq-6kg-pla-2-0-upgraded-pla-pla-plus-3d-printer-filament-1kg.html"},{"handle":"pla-plus-1kg-filament-filamento-offerta-bundle-sunlu","title":"[Min. 6 bobine] Filamento PLA+ PLA Plus per stampanti 3D, 1 kg","category":"Filaments","price":"$11.89","image_url":"https://cdn.shopify.com/s/files/1/0704/0027/8683/files/PLA_PLUS_Grey_3766df20-97d7-4339-9f0a-de45fd0bef1e.jpg?v=1778219616","sku":"DLZ-EU-SL-PLA+-GY-1KG","href":"/product/pla-plus-1kg-filament-filamento-offerta-bundle-sunlu.html"},{"handle":"over-3kg-bundle-sale-petg-3d-printer-filament-1-75mm-1kg-roll","title":"[Min. 6 bobine] Filamento PETG per Stampante 3D 1KG","category":"Filaments","price":"$10.39","image_url":"https://cdn.shopify.com/s/files/1/0704/0027/8683/files/PETG_RF_WT.jpg?v=1773221311","sku":"DLZ-EU-SL-PETG-WT-RF-1KG","href":"/product/over-3kg-bundle-sale-petg-3d-printer-filament-1-75mm-1kg-roll.html"},{"handle":"bundle-filamenti-3kg-colori-assortiti-pla-pla-plus-rainbow-silk-matte","title":"Bundle da 3 kg di filamenti in colori assortiti – PLA Matte, PLA Rainbow e Silk Multicolore","category":"Filaments","price":"$35.89","image_url":"https://cdn.shopify.com/s/files/1/0704/0027/8683/files/bundle-3kg-pla-matte-black-white-gray.jpg?v=1791350637","sku":"DLZ-EU-SL-PLAYG-BK+WT+GY-1KG*3-COMBO","href":"/product/bundle-filamenti-3kg-colori-assortiti-pla-pla-plus-rainbow-silk-matte.html"}]}}
