More Seachem Purigen or Matrix?
I have a Fluval C4 Power Filter (HOB) on my 36 gallon freshwater tank housing a fair number of fish. Currently, I have the foam pad, a small bag of Purigen, but mostly Matrix in the filter. My filter does have a very large chemical media basket which is about 3/4 filled with Matrix and 1/4 with Pruigen. Then, there is a small-ish bio-media basket above that with more Matrix.
My levels have been good... 0 ammonia/nitrite 40 nitrate (is that nitrate a little high)?
Would I be better off replacing some of that Matrix with more Purigen? Basically, which has the better Ammonia/Nitrate/Nitrite removal ability? Which should I have more of? Should I just fill the entire chemical basket with Purigen and then leave the Matrix in the top bio-basket?
Thanks in advance!!!

From what I see online, Matrix is a bio media and the Purigen is a chemical media. I would add more bio media.
Your nitrates are way too high at 40 ppm. What is your water change schedule and what fish are in your tank? I would do a 50% PWC now and another 50% PWC tomorrow to get your nitrates down as close to 10 ppm as possible. Weekly 40-50% PWCs and not overfeeding are the way to control nitrates.My 75 gal Journal & My Dual 29 gal Journal

+1 to the above, adding more bio media such as matrix is a better idea, I have about 5 lb's or more in my sump but as stated the only way to lower nitrates is with water changes and not over feeding. I do one 50%+ on my 45 gallon weekly and four 50%+ water changes on my 135 gallon per week._______________________________________________

Before starting a new regime of huge water changes, you'll want to test your tap water. not much point doing water changes if the water coming out of the tap has nitrates of 40 (like my last place). In that case, using purigen or the like, or loading up on anaerobic substrate will be your only possible options, and the anaerobic substrate is the least used or proven method.

Very good point about the tap water possibly having nitrates... it's something I luckily never dealt with but absolutely a good starting point to check first._______________________________________________
