1. from the pics, u are using SP3000 to feed the NR1000. But SP3000 is a fix rated pump(ie 3L/H), if so how to increase or control the drip rate of the NR1000.
2. Does the NR1000 need continuos feeding of denimar powder? I thou once the bacteria is establish, the deniballs in the NR1000 will feed the bacteria there is no need to feed the NR1000 w denimar powders again.
