Hi qian hu,
thank your for the fast response, much appreciated!
i have 4 rays 13-14" and 4 aros 20-25" in a 6x2.5x2.5, and feed twice to thrice daily, so i have extremely high bioload
WC 50% every 2-3 days to maintain nitrates below 100, it'll be great if utilizing a hydra stream 3 could help reduce ntirates noticeably, i'll be very happy with around 50-60ppm.
was hoping that since the water that would pass through the hydra would already be cleared of most, if not all, NH3/NH4/NO2, the hydra would have a higher chance of working on the NO3. reducing NO3 gradually is fine, as long as at the end of the day i can see the results
going to PM u now for the test results.
thanks again.
