Changing a tanks water to many times a hour?

I have a 30g oceanic cube with a rio 20 (1290 gph) return pump, that means that I'm changing my water over in the tank up to 43 times an hour is that to much?

The water is the same, it's just circulating. 43x turn over is good. With 280 TWV I wish I could achieve 43x turn over.

yup. not a problem. i have a mag 12 runing my closed loop and a mag 9 return. it's a 45 gal tank. i do turn down the flow a bit though. heh.

Thanks for the replies; unfortantly last night my cuke fond his way into my siphoned drain (he also died in getting sucked up... didn't nuke everything though just got stuck). It screwed up the flows in my sump a piece of gravel found its way to my pump and stoped it. I think it burned the pump up but I didn't have time this morning, so no more changing the water over a ton of times an hour :(

back to only changing the water over 10 times per hour

It depends on what you plan to keep. If it is SPS then great. If it is something else then it could be way too much (ie LPS only).

Also be careful that the water does not flow too fast over your filter if using a wet/dry filter or submerged filter in your sump - the bacteria needs time to process the ammonia and nitrites.
