Spider wood and tannins

[Alec]

For those of you who use spiderwood...does it leak tannins? If so how badly does it turn the water?

I get very little tannins with spiderwood. I have hard water.  7.6 ph

spiderwood doesnt tint water too badly. now it will grow a nice white fungus for a short time after being put in a tank. that is unsightly , but hurts nothing and goes away after a while.

I purchased some spiderwood and have been trying to rid the wood of tannins. Unlike some hobbyists, I'd rather not have yellow tinted water. However, I've been simmering-low boil the wood for about 3 weeks, for about 8 hours per day. At first, the boiled water was very yellow. Then, the water color decreased substantially. For the past 4-5 days, even though the yellow color has diminished further, it appears to have reached a steady-state, at least as far as I can view. That is, the yellow tint remains at a low level. Perhaps it is the higher temperature that the spiderwood is being subjected to which releases the tannins, which would not be noticeable at 75 degrees. Of course, I could go ahead and test this straightaway. But, before I do, any thoughts on eliminating tannin release? Thanks.

I have two moderate sized pieces of spider wood in my tank and have noticed zero water color change. I did get the aforementioned white fungus for a bit but it’s all died now and my Otocinclus eat it like candy.

@Knew tooth is I do believe the boiling is releasing tannins. I place huge pieces in my tanks after just rinsing and barely see tannins. I run both crystal clear tanks and heavy tannin tanks. Ones I want sparkling clear I use spider wood. Mopani for dark water.
