Doc 9002 Micro Bubbles

[maxijaza82]

I have a tunze Doc 9002 set up for more than two months and happy with the skimate im getting. But Im having a problem with bubbles coming from the bottom of the skimmer. Ive tried moving my power heads, moving skimmer etc to change flow, No change. Also took skimmer apart to clean and make sure there were no leaks. Any other ideas.

The skimmer does emit a few microbubbles periodically, if it is a lot, possible culprits are a very high KH, oxygen saturation due to rapid growing algaes or corals or the green jet pipe is not connected to the end of the venturi nozzle. If the KH is above 14 stop adding any KH raising additives- 2 part, buffers, kalk, etc. If the problems gets worse as daylight hours progress it is oxygen saturation, reduce the photoperiod or thin out the corals or algaes. Check that the jet pipe is attached and is inserted through the internal baffle plate.
