Your anemone is likely to kill anything in its path.

thanks for the reply. we did the water moving real fast at him and he seemed to loosen and moved back to other side of the tank.


unrelated question. we are setting up our sump and we have a mag 7 return pump. and we have a ball valve coming from the main tank to control the flow. but we cant seem to get the flow right, either the main tank starts to overflow or the sump starts to go dry. any suggesions on this???????????

As long as your overflow from the main display aquarium is adequate to handle the volume of water pumped by your return pump, you have no problems. If your return pump is too powerful for your overflow, you would have to use a ball valve on the return pump's outlet to reduce the flow from the return pump.

You seem to be saying that you have a ball valve on the drain line coming down from the main aquarium, right? I have a ball valve on the drain line from my aquarium, too, but that doesn't control flow, only the pump itself controls flow. I keep my ball valve on my drain line partially closed in order to create back pressure and reduce noise but I have to be extremely careful that it is open enough to accomodate the flow from my return pump, otherwise the aquarium itself would overflow. Actually before that would happen my sump would run low and my return pump would start pulling air.

Anyway, the only way you control the volume of water through the system is by regulating the flow from the return pump itself. That means that you have a ball valve just above the pump's outlet. A ball valve on the drain line is useful for a couple of other reasons but it does NOT regulate the volume of flow through the system.
