KH is essential for pH stability and provides the buffering capacity your pond needs to resist sudden changes caused by rainfall, heavy feeding, bacterial activity, or seasonal shifts.\n\u003cbr\u003e\u003cbr\u003e\nA steady KH level supports a healthy, efficient biological filter by helping beneficial bacteria perform consistently. When KH becomes depleted, ponds can become vulnerable to rapid pH swings and “pH crash” events that place fish under stress and can quickly destabilise water quality.\n\u003cbr\u003e\u003cbr\u003e\nRegular KH testing and maintenance is one of the simplest and most effective ways to keep koi and pond fish thriving, especially during periods of high filter activity, warmer months, or after large water changes.\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e\u003ctable style=\"width: 100%;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 100px; padding: 0px;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0943\/9238\/5910\/files\/powerful-green-nt.jpg\" alt=\"icon to indicate essential treatment formula\" width=\"86\"\u003e\u003c\/td\u003e\n\u003ctd style=\"vertical-align: top;height:100%;\"\u003e\n\u003cstrong\u003eEssential Treatment\u003c\/strong\u003e\u003cbr\u003e\u003cstrong style=\"color: #10a54a;\"\u003eKoi Doc \u003c\/strong\u003e KH+ strengthens your pond’s buffering capacity, helps prevent pH crashes, is fast dissolving and easy to use, works all year round, helps your benefitial bacteria and is fish and plant safe.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 100px; padding: 0px;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0943\/9238\/5910\/files\/plant-green-nt.jpg?\" alt=\"icon showing safe for plants fish and microorganisms\" width=\"86\"\u003e\u003c\/td\u003e\n\u003ctd style=\"vertical-align: top;height:100%;\"\u003e\n\u003cstrong\u003eSafe for plants, fish and microorganisms\u003c\/strong\u003e\u003cbr\u003eWhen used as directed, \u003cstrong style=\"color: #10a54a;\"\u003eKoi Doc\u003c\/strong\u003e KH+ is safe for koi, pond fish, plants, and beneficial microorganisms.
