hi,
i recently got a Eheim 2231 for my 1.5ft tank, not planted tank though. http://www.eheim.de/e/Zubehoer.cgi?M...er=Gesamtliste
if you check in eheim's site, this seems to be the only canister recommended for less than 100litres. http://www.eheim.de/e/eheim.htm
let's see what other planted tank members will advise?
cheers!
