So while the scrubber is braking in and actually start having an impact at lowering my nutrients, i decided to take matters into my own hands, so po4 i was able to bring down no problem with some phosphate RX it is now at 0.03 and not rising yet, however my nitrates is what im having an issue with, even after doing a 40% water change followed by a few smaller ones and bringing it down to 10 within a week ill be back at 30 any ideas what can be the issue?
