Resin pouches

[petros]

Hello guys! In my canister filter I have a phos Zord pouch for phosphates removal. And Im thinking to add at the same filter a resin pouch for the nitates (Nitra Zorb). Do you know if there would be any problems for the water :?: I should add that Ive done whatever I could think, to reduce the nitrates but with no result :x

Nitrazorb works very well and causes no problems but the only really correct way to remove nitrates is by increased water changes
