Even when I vacuum deep along the front, it is very fine particles that come up. Partly due perhaps to fish, I remember when I had some larger plecos there would be much more noticeable mulm than with my smaller fish. Livebearers for instance produce more visible waste (in size) than characins.

One further point in relation to this, on water changes. It is commonly held by a majority of natural planted tank aquarists that water changes are not necessary and should not be performed regularly if at all. I have not embraced this thinking...yet; but it is held by Diana Walstad and Tom Barr, both highly respected experienced aquarists with professional training in biology and microbiology. Mr. Barr has a BSc in aquatic biology, a MSc in Botany, and is currently pursuing a PhD in Plant Sciences. I have had some very rewarding and informative discussions with him. If one does no water changes, one is obviously not vacuuming anything from the substrate.

Nature is indeed amazing, if we only let her get on with it.

On the water changes thing... where did you find that info? Online?

to be honest...you tube! but there are often threads (and many started by yours truly) about water changes, frequency and amounts, processes.

I'll try to find a couple recent ones that i thought were useful and pm you.

Diana Walstad's book Ecology of the Planted Aquarium mentions it, and she has articles on the Aqua Botanic website.

Tom Barr has his own website and is a member of another forum, and he and I have exchanged thoughts on this.

It is not anything new, for many years planted tank aquarists have held the view that water changes in planted aquaria should be minimal to non-existent. There are very good rasons why. But you can't take this at face value, there are issues and balances, some of which I have mentioned in various threads here.

So I guess the plants would absorb just about every kind of waste and by-product... Makes sense I guess.
My tank is no where near planted enough for that, but when I give my girl a tank I'm going to plant it heavily... knowing her, she'll forget the wc...

lots of food for thought, i will definitely be doing some reading on this. I have two tanks one is a 10g betta tank that used to be a HEAVILY planted female sorority, that just seems to excrete gunk from the substrate, the other is my 20L current betta sorority, both just seem to do incredible stability wise. there might be something to this....

edit: they do incredible if im meticulous about keeping the gunk from accumulating on top of the substrate, which is a nightmare until i get most of it out of there...
