Might want to cut back on the feeding and not use any frozen meat types they are full of NO3's like Brine and Mysis shrimp are loaded as most meats are. And it just stays in the system unless you have a way to deal with them I use a coil dennitrater myself.. DSB and L/R do not now or never had taken care if this problem as advertised . Even with a few fish .. Then they went to adding Vodka and or sugar carbons to feed the bacteria to consume the Nitrates .. I' don't suggest this and would never apply the goofy idea myself But then I also won't use a DSB either (: _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) |
