I actually have one of those
small pumps , which i used earlier for testing purposes but i wouldnt bet my system on it . For robustness and reliablity , my eheim 1048 takes the cake (and it's twice the size of the Aquael ).
Anyway, it is an interesting test but the target market doesnt usually use such low flow pumps. So i was wondering, are you thinking of other fittings for the Cascade? Something like the plug and cool , or Innovatek or similar fitting , very popular in Europe ?
