I bought this but it is way too strong for my 60 gal Bowfront. Turned my peaceful tank into a Jacuzzi, fish are hanging on for dear life. Too much trouble to send it back to Amazon. I would like to trade for LPS. It was in my tank for about two minutes. Put it back in the box. The Amazon link is pasted below, but not sure if it works. It is a Songjoy Wave Maker JVB 2020AB. Paid $30. Looks like it would probably work in a 100 gall tank. https://www.amazon.com/gp/product/B01J19M9D6/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
