In ponding/watergardening circles, decaying barley straw is said to release
algae retarding chemicals and prevent new growth of string algae. Probably
the same principle as the decaying peat. I have used barley straw in my
watergarden successfully to combat string algae, but my water turned
brownish, so I discontinued using it.

I found a great website that gives lots of info on apple snails including
how to tell which ones eat your plants. According to the site, some of the
most common ones sold are:
Pomacea bridgesi : won't eat healthy plants
Pomacea canaliculata : will definitely eat your plants
Pomacea paludosa : doesn't say
There's also pretty detailed info and some diagrams and pictures on how to
tell them apart. I think the one I have which hasn't been eating my
watergarden plants so much that I would notice is either the second or
third. Don't think it's the first. Anyway, it's a great site for loads of
good info on apple snails and some info on other types of snails as well.
Here's a link.
