“Very Good pump - powerful & small. I wish now that had bought the controllable version as I have only a small tank & the flow really should on pulse mode.”
“Is about the size of a baseball so quite a bit larger than the Nanostream 6045 I already have in there. I have it in a 400l fish only marine. Impeller rattles for a split second on startup so you wouldn't want it on a wave pulse timer. Quiet hum otherwise that improves over time, like most pumps restarting it seems to trigger different hum tones so give it a few goes. Fish seem happier am hoping it keeps the algae down too. It comes with a sealed European 2 pin plug that is plugged into a 3 pin UK adapter which is easily removed.”
