Not yet. I have been out of town. I called several times and all I got is an answering machine and I did not leave a message because I knew I would be out of town. Since I am now back home, I will call tomorrow and leave a message and wait for them to call. I will let you know as soon as possible. I think there might be a way to modify the filter if it is too powerful by using simple filter floss and not using the regular filter cartridge that comes with it. But, in any event, I really want to take a look at it in person and I will definantly be able to tell you if it is Betta friendly and also what modifications (if needed) need to be done to make it Betta friendly. I am not looking at that tank for a Betta tank. I am looking at that tank for a small Reef tank.
