Only use on healthy plants. Plants don't take up CO2 in the dark, so don't add the tabs shortly before lights off; No Mercy says the CO2 stays in the water for about 4 to 6 hours. Your pH may dip slightly for a while.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSizes:\u003c\/strong\u003e 60 tabs and 150 tabs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFree UK delivery\u003c\/strong\u003e on orders over £94.99, or free Click \u0026amp; Collect from our West Bromwich shop.
