I am boiling some driftwood that I bought online. A lot of tannins leeching out. Anyone have an opinion on what the effect of tannins are on algae growth in tanks? I have a tetra and amano tank so I feel confident the tannins and water softening won’t harm them, but I am constantly changing the water and clearing away green algae and brown fuzzy algae (not diatoms) so wondering if tannins will accelerate that?
