Hi,
I installed since 1 month in my tank 2 stream 6100, between 10 and 15 cm of the surface of water. However I regularly note a rejection of bubbles of air of these stream.
From where that can it come?
Did somebody already have this problem?
Because I don't think that corals and stoups will like that.
Because the evening, when I comme back, I note manitenant bubbles of air on certain alive stones.
Thank you.
PS. Sorry for my english.
