    Hi all,

    Here is a picture of the waterfall in my weirs.

    Do you think this is sufficient to limit the degassing effect?

    Or, should I also try to cover it somehow?

    Just checking.

    Yes, that is Riccia growing emersed on the right side of the ''gate'.

    Thanks.

    That is about the level of overflow that I have also. I found that I had to add a tad more CO2 to compensate. But I'm already seeing marked improvements. Long term will be the true determination though.
