I am looking at adding some Seachem Matrix to the two Canister filters (both Aquatop CF500UV) on my 120G tank. I have heard mixed reviews on it's effect on reducing nitrates. Does anyone have an opinion on it's ability to reduce nitrates in a canister filter? Also any thoughts about Matrix in general? I would also welcome input on how much to add. My tank is fairly heavily stocked and nitrates usually run about 40-50 with weekly water changes of between 40-50%.

Why do you have high nitrate? Is it in your tap water,bio-load, etc...
"Matrix" is "Pumice Rock." Go online like amazon or other places & buy it as it will be cheaper.
Now, if i recall correctly if in a canister filter there is just tooo much flow. If you go this route your will have nitrifying bacteria. What you are look for is a flow rate of 20-40+GPH is what i believe was the target for claims to be able to house the anaerobic bacteria. (think reef live rock) Best to control the flow with a reactor type canister. I know they have another product that is used to do this but that is up for debate. I will first fing out why such a high rate of nitrate at the end of the week first.

Sounds like the stocking level is the problem.
