Q: If I’m using Matrix™do I need to use de*nitrate™as well?
A: That depends on a number of things. If Matrix™is doing the job for you (i.e. keeping nitrite/nitrate under control) then, no. If you’re running a flow rate higher than 50 gallons/hour, then you won’t be able to use de*nitrate™anyway since it requires a flow rate slower than that to support the denitrifying bacteria. If filter size and capacity are an issue, then de*nitrate™will provide a more efficient removal of nitrate per volume of product (i.e. you can use less de*nitrate™by volume than Matrix™to get the same denitrifying capacity). Also, de*nitrate™has the capacity to remove nitrates by chemical absorption on initial use of the product, although if nitrate levels are very high (above 20 mg/L) we recommend a water change as the most economical approach to getting your nitrate level down before putting these products into service.
