Comments and a quick question RE: PURIGEN

I bought the pre bagged Purigen today at my LFS, after reading success stories for clearing up tannins...

Well after 6 hours I can honestly say WOW! what a difference! Its not 100% crystal clear but a huge improvement!

Now my question is, did it clear up the water enough to allow more light to penetrate the water? I noticed that my plants are pearling even more than before? Do tannins block light?

Thanks Josh

Yes, tannins do block light. Their removal can allow more light to reach your plants.
