Above all, sudden changes in water parameters must be avoided. In addition, many substances dissolved in water are subject to changes depending on the pH. For example, the amount of CO2 that can be dissolved in water is directly related to the pH value. Therefore, the pH value can serve as a simple control variable for setting up CO2 fertilization systems, as long as there are no other acids (e.g., humic acids) in the water that affect the pH value.\n\nThe optimal CO2 concentration for plants and harmless to fish is achieved at a pH of around 6.8-7.3. The carbonate hardness should not be below 4° dH. Accurate pH measurement may also be required for special applications, such as fish breeding. In the garden pond, but especially in the aquarium, if there is a lack of CO2, algae in particular, due to their rapid assimilation during photosynthesis, can consume the hydrogen carbonate in the water (biogenic decalcification) and thus bring the pH value to dangerous levels for fish (above 10). Thanks to JBL ProAquaTest Co2-pH Permanent, the pH value and carbon content can be constantly measured and quickly reported.\n\nApplication: Place the reagent in the long-term test device and attach it to the aquarium panel using suction cups. Compare the color of the reagent with the sticker on the color scale and read the value.\n\n\n\n\u003c\/pre\u003e\n","brand":"JBL","offers":[{"title":"JBL ProAquaTest CO2 \/ pH Permanent - test for measuring pH and CO2 in water","offer_id":55159853777270,"sku":"2413800","price":17.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/9881\/9105\/files\/054c28a2d4ab98f478cea6f3cd19aea3.jpg?v=1758892689"},{"product_id":"jbl-proaquatest-mg-reagens-reagent-za-izmervane-magneziy-25-testa","title":"JBL Proaquatest Mg Reagent - reagent for measuring magnesium, 25 tests","description":"\u003cp\u003ereagent for magnesium measurement\u003c\/p\u003e\n","brand":"JBL","offers":[{"title":"JBL Proaquatest Mg Reagent - reagent for measuring magnesium 25 tests","offer_id":55331764633974,"sku":"2414300","price":12.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/9881\/9105\/files\/processed_0_46f5a6a4-28f0-4386-989a-093d49f582a6.jpg?v=1755691633"},{"product_id":"jbl-proaquatest-k-reagens-reagent-za-izmervane-kaliy-25-testa","title":"JBL Proaquatest K Reagent - reagent for measuring potassium 25 tests","description":"\u003cp\u003epotassium measuring reagent\u003c\/p\u003e\n","brand":"JBL","offers":[{"title":"JBL Proaquatest K Reagent - Reagent for potassium measurement 25 tests","offer_id":55331764896118,"sku":"2413100","price":18.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/9881\/9105\/files\/processed_0_b8b979f8-5b7b-474a-b1cc-0d1a5cb358a9.jpg?v=1755691636"},{"product_id":"jbl-proaquatest-cu-reagens-reagent-za-izmervane-med-50-testa","title":"JBL Proaquatest Cu Reagent - copper test reagent 50 tests","description":"\u003cp\u003ereagent for copper measurement\u003c\/p\u003e\n","brand":"JBL","offers":[{"title":"JBL Proaquatest Cu Reagent - copper test reagent 50 tests","offer_id":55331765125494,"sku":"2411500","price":9.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/9881\/9105\/files\/processed_0_d9917903-a73e-48cc-ba29-41810394c9bb.jpg?v=1755691639"},{"product_id":"jbl-proaquatest-ca-reagens-reagent-za-izmervane-kaltsiy","title":"JBL Proaquatest Ca Reagens - reagent for measuring calcium","description":"\u003cp\u003ecalcium measurement reagent\u003c\/p\u003e\n","brand":"JBL","offers":[{"title":"JBL Proaquatest Ca Reagent - reagent for measuring calcium","offer_id":55331765322102,"sku":"2413300","price":10.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/9881\/9105\/files\/processed_0_e0b0fff5-da8b-4f94-bd6b-69d30ada818e.jpg?v=1755691643"},{"product_id":"jbl-proaquatest-co2-reagens-reagent-za-izmervane-vagleroden-dioksid","title":"JBL Proaquatest CO2 Reagent - reagent for measuring carbon dioxide","description":"\u003cp\u003ecarbon dioxide measuring reagent\u003c\/p\u003e\n","brand":"JBL","offers":[{"title":"JBL Proaquatest CO2 Reagent - reagent for measuring carbon dioxide","offer_id":55331766993270,"sku":"2413900","price":8.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/9881\/9105\/files\/processed_0_e4575994-8400-46cd-8b94-9fc69755a054.jpg?v=1755691646"},{"product_id":"jbl-proaquatest-no3-reagens-reagent-za-izmervane-nitrati-40-testa","title":"JBL Proaquatest NО3 Reagent - reagent for nitrate measurement 40 tests","description":"\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003eDetermines the optimal nitrate value for perfect plant growth or a possible cause of algae growth in fresh and marine water.\u003cbr\u003eLaboratory comparator system to compensate for the inherent color of the water: fill glass vials with water sample, add reagents to one vial, place vials in holder, read values from color chart.\u003cbr\u003eUsage: for new freshwater aquariums: 1 x weekly.
