Flourish Excel provides bioavailable organic carbon for planted aquariums, including situations where adding more CO2 could result in dangerously low pH. It can be used on its own or alongside CO2 injection; using it does not necessarily mean stopping CO2 use.\u003c\/p\u003e\n\u003ch3\u003eHow does Flourish Excel support plant photosynthesis?\u003c\/h3\u003e\n\u003cp\u003eFlourish Excel supplies a compound structurally similar to photosynthetic intermediates that plants use in building longer carbon chains. This gives plants a route into the carbon-chain building process that bypasses the involvement of CO2 in that process. It does not contain the specific intermediates ribulose 1,5-bisphosphate or 2-carboxy-3-keto-D-arabinitol 1,5 bisphosphate.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePlants produce photosynthetic intermediates as part of photosynthesis.\u003c\/li\u003e\n\u003cli\u003eThe supplied compound is structurally similar, rather than one of those specific named intermediates.\u003c\/li\u003e\n\u003cli\u003eSimple chemical or enzymatic steps can convert it into those or other related compounds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow much Flourish Excel should I use?\u003c\/h3\u003e\n\u003cp\u003eFor initial use, or after a major water change of more than 40%, dose 1 capful (5 mL) for every 40 L (10 US gallons).

Flourish Excel can be used with CO2 injection, and it is described as completely safe for fish.

Its dosing directions also make it suitable for routine use and after a major water change. For aquariums containing Anacharis, follow the every-other-day schedule rather than dosing daily. It combines a defined aquarium dosing routine with carbon support and iron-reducing properties for planted tanks.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How do I dose Seachem Flourish Excel?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: For initial use or after a water change over 40%, Seachem Flourish Excel dosing is 5 mL per 40 L.
