is it possible to have over 20ppm of o2 in my reeftank's water column? my temp is 75'F, salinity is 1.0255, i expected to around 7ppm but the test never changed to the indicated color code after 20 drops! (1drop of regent=1 ppm).
i have a very very high current flow in my tank, around 1400gph bi-directional every 2 hours when the powerheads overlap each other. also there is approx 600gph cycling from the sump/fuge also. so is too much o2 a good situation to have or a bad situation if these test results are somewhat accurate?
thanks in advance!
