If I set up a special filter with de*nitrate to lower my nitrates, will it use up or require additional flourish excel to the system? What about CO2?

Thanks for posting! De*nitrate will have no impact on Flourish Excel or CO2, therefore, it will not be necessary to add any more than the recommended amount of the product. I hope this was helpful and please let me know if we can be of any further assistance!
