Aloha Lasse,
This 12 gal was one of my tanks a few years ago. It's my Utah-Hawaii tank with rock and sand from both places. The anemones stayed put. It used only one powerhead (and it's hidden from view
). The flow and wave action is surprising.The positioning of the powerhead makes ALL the difference. It is something I can describe but the full effect is not seen in the pic or the description. Feel free to drop by and see for yourself.
Mahalo,
Mark
