I'm running EcoBaks with a HOB eshopps. I drilled a hole large enough into the skimmer inlet pipe(a portion that's still inside the tank) for my reactor output line to fit into.I'm not exactly sure if this is eliminating the beneficial Nutrition my coral are supposedly supposed to be getting with bio-pellet use,though I'm sure some makes it into the DT,at least I hope . I didn't plumb the reactor outlet that way out of necessity though,as I hadn't noticed any bacterial slime growth anywhere in the tank.Just out of suggestion. Running the pellets for the last 2 1/2 months I can say my Nitrates remain @ 1ppm tested with Elos. My PO4 has been 0 as tested with Salifert for the last 4 months at least. I perform weekly 5 gallon WC's and feed daily. I'd like my Nitrates to be 0.Still develop the film algae as well that requires scrubbing at least once every two weeks so I know their's nutrients available. Following along to witness your experience with dosing.
