Bro, thanks for taking the effort to explain to me the schuran and the picture.
Now i have more confidence of schuran.
Mine is the Schuran Jetskim 150 model, so far no skimmate yet but can see that the bubbles are more fine than ytd.
Chris, i see the schuran is working very well for you. Thanks a lot.
Currently the salinity level is 1.017, zero livestock and fishes. could this be the reason for the low count in bubbles?
