Help with nitrates

[makana]

I changed the flow the best I could but its pretty much impossible to avoid dead spots in a nano cube. I use a turkey basted on the rocks every couple days.

I don't really want to put a pellet reactor on it. The tank is already running way more equipment than I wanted. But I guess that may be my only way out at this point.

I don't think I've read about bleaching the rock. It sounds a little harsh and I would expect the rock to be dead after that. I guess if that's the case I could buy dry rock and swap it in for live over time.
