Lately I've had a problem with nitrates creeping up into the 50-60 ppm range again, which I already know how to handle it with the usual maintenance (weekly 25% - 50% water changes depending on nitrate levels). Normally I wouldn't be terribly concerned, but I have Rams in the tank again and I know how sensitive they are to nitrates and I need to get it under control soon. I would be happy if I can get it back into the 20-25 ppm range again. I will also be introducing Seachem Matrix into my canister filter this weekend, so that should help. My question is, and I should have asked this ages ago.... how much food should I feed my fish? I wonder if I'm overfeeding them? All this time I didn't think I was since they eat everything I feed considering how many fish are in the tank, but now I'm beginning to second guess myself.
