[APD] Driftwood, tannins and calcium deficiency
My aquascape contains large pieces of massive driftwood.
Question: Does the leached tannins chelate Ca/Mg
rendering it useless to the plants but still can be
measured by GH and Ca-tests?
(My snails get less translucent when I dose CaCO3 or
smashed chalkboard crayons, and the Ca-deficiency
gets less visible in the plants. More frequent waterchanges
seems to do the trick also.)
(Something is messing with my Calcium, so I will not
give up on this 8)
