i looking into upgrading my close loop pump. my tank is drilled with a 1" close loop return and i'm running a coralife turbo sea 1100p (same as blueline hd55 or panworld 1100p). The flow is good but not as much as i want for good sps growth. so i'm considering upgrading to a larger pump. i've read a few threads about the sequence pumps producing heat and the ampmaster pumps having leaky seals...

1. i'm thinking of running a sequence dart for the close loop with a 1.5" input and output.. do u think the 1" return from the tank will work. also looking a the ampmaster 3000.

2. has anyone with one of the 2 listed pumps had any problems with heat or leaks?

3. is there a better pump then to use then the ones listed as far as heat and watts used?

thanks
