Substrate/Lave stones
Hi folks,
I've been an irregular customer here since 1999, not posted much, so my word will not really mean much. That said... *Don't* put any substrate or lave stones into your pond when you have fish/koi. I cleaned out my pond today (digging a bigger one) and I was honestly disgusted with the lava/poo mixture I found in there. Sure, I only had 3 pumps going 24/7 doing 30.000 litres an hour, but still... utterly repulsive. Nothing new, most koi sites seem to agree, but I've seen it with my own nose... horrid smell, disgusting. Just don't do it :-) A bottom drain might be wiser.

Substrate/Lave stones
Theo, I started off with a nice little 100 gal. preform, into the bottom of
which I poured 1" gravel to the 2" mark. Two months later, I installed my 1200 gal. pond. When I removed the rocks from the 100 gal., the smell was enough to gag a maggot! And that was only after 2 months, with a lot of plants and 3 little fish! Needless to say, the larger pond, and the tank I'm building in the back yard, are rockless. Rocks are fine for watergardens, but are NOT suited for places where there are animals. The only way I can endorse a rock bottom would be if very large rocks were used, and they were mortared to the bottom/sides. That would not allow the accumulation of the gunk (as readily, at least). However, after a few months, everything gets covered in algae anyway, and you can't see them - so why bother? Lee "Theo van Daele" wrote in message ...

And if you have a gazillion plants directly into the gravel, they probably
do! But pond plants are usually containerized, not directly planted. BIG difference! And I've come across some pretty gross aquarium gravel, too!
