SUMP CIRCULATING FOR SHORT WHILE ONLY :-(

Well - I had water going for a while but the pump was resonating so badly that it did not last for long. I will have to find something a little lighter and quieter to function as the main return pump.I was hoping to create a great deal of turnover through the sump and also the main tank (was aiming at about 20x volume) . This has resulted in an overflow that sounded like niagra falls . The pump I used was probably a bit of overkill (5000litres/hr at 2m).

I will downgrade and go for about 2500l/hr using a much smaller pump.

Update to follow.

Happy Reefing.
