Many plants can crack carbonate or bicarbonate ions to get their carbon.
In such a small tank I imagine that six plants could do that pretty
quickly. I bet that's what's happening. Try increasing your CO2 a bit
and see if it doesn't stop dropping. The carbon is CO2 is easier to get
at if it's abundant.
