OK, Thanks to Elaine I now have ordered my pump - who can recommend a lond
airstone 30 - 45 cm to produce a line of small bubbles (fizz?).


Google is treating me well again (it's kind of a fun challenge - like a
treasure hunt!). Here's a UK mail order site that has the air curtains
so you can see what I'm talking about.

Aqua Fizzzz gives bubbles like a standard airstone. I used to have a 6"
one in one of my tanks. Hagen air curtains give somewhat finer bubbles
in a nice wall. I wouldn't call it fizz, though. Ceramic airstones
produce very fine bubbles more towards a fizz, and wooden skimmer
airstones really fizz - until they get clogged with algae and stop
working at all.

I've not seen the Interpet or Algarde ones in action since those brands
are rarer in the US.
