I bought this Saturday from a LFS selling it as spiderwood and was told it wouldn't leach tanins and no need to boil... Although I did, for 6 hours. Changing the water out halfway thru. Both times the water was very dark brown. I let sit in a bucket of tap for about 20 hours and no more leaching and it was starting to sink well. So I added it to my tiny little fluval edge 6gallon which is fairly heavily planted and has perfectly clear water and no algae. This pic was the next morning but as the days passed the water started gettin a little darker and my ground cover plants (name has the word cardinal in it) started to look dull in color and lifeless. Usually very bright green and perky. Also the glass started to get a very fine green algae cover on them making the glass appear dirty. I cleaned manually (not easy in the edge especially with all of these item in here). I started to question whether or not this is actually spiderwood... I did some googling last night and found it looks much more like something called redmoor wood. Anyone know? And any suggestions...do I let this play out? Thanks a million!
