You get one 250ml bottle, suitable for ponds within the range given in the sizing guide.\u003c\/p\u003e\u003cp\u003eOverview Velda KH Plus is formulated to raise carbonate hardness (KH) specifically, rather than general hardness (GH), giving you a dedicated way to correct that particular part of your pond's water chemistry.\u003c\/p\u003e\u003cp\u003eGetting KH to a satisfactory level helps fight acidity in the pond and keeps conditions right for oxygen-producing plants, because it makes carbon dioxide available to them in a bound form.\u003c\/p\u003e\u003cp\u003eIt's suitable for pond keepers who have tested their water and found KH running low, rather than those needing a GH adjustment.\u003c\/p\u003e\u003cp\u003eKey benefits Targeting KH on its own means you can correct it without unnecessarily disturbing GH. It also supports plants that produce oxygen, by making bound CO2 available to them as the KH value rises. You receive one 250ml bottle of KH Plus per purchase.\u003c\/p\u003e\u003cp\u003eChoosing your size This product is offered in a single 250ml bottle size.
