Have ordered the small fountain for my Minipond (half a wine barrel). Unfortunately, I had to supply immediately allowed to return because the fountain was obviously already used (earth on a spit and a crack in one of the fitting members of the fountain). But Exchange was not a problem, traders sent immediately to a return slip. In order for the fountain at the right height, I put him on a small upturned flowerpot. Others have described that they can not use all the essays because the power then for a barrel is too large and the water gushes over the edge. If you increase the center hole of Aufätze with a small scissors and therefore the water pressure increases through this hole, bubbles not as strong and everything remains within the limits of the other holes. Unfortunately, it's really so that even the smallest haze clouds or shade of swaying sheet sufficient to bring the pump to a halt. Is for me but not bad. Property me the fountain mainly because of oxygenation ordered (so that the water does not tip) and these stretch a few hours splashing day out completely.
