Dear Mr Tunze,
I now own 2 of your excellent Nanostream 6040 pumps, however, even though I understand the concept of your open outlet design which my fish also understand my black sea cucumber did not. I say did as in the past tense as it is no more, it is breathed of life and gone to meet it's maker if it hadn't decided to investigate the blue little spinning thing it would be happily crawling along cleaning my sand. Now a simple 2 or 3 bar cage would have given my little sand cleaning friend a fighting chance but alas your lack of a simple design put and end to this remarkable fellow who will be sadly missed.
yours sincerely
Mr L J Cucumberless.
