This is all very true. Can't agree more.Yes. Absolutely possible to have clear water with Natural tanks.
Depends on how much driftwood you use (and how 'mature' it is); how much tannins your soil releases and if you have some sort of filtering going on.
My brother has a small 5g and it has always had yellow water. He wants it that way. Its got soil, driftwood and no filtration at all. Just a little water movement.
I've done a bunch of tanks with soil and driftwood; got some minor yellowing at first; but then they become clearer as the wood matures. Even without mineralized soil. But I use filter with carbon for the first month or so.
Yeah. It depends what your standard for crystal clear is.Guck said it best when he say's 'his standard' of what clear water is. I think most ppl will say that their water is clear even if it's a lil' stained. *Crystal* clear water IMO is color free.
