It will do for now, as long as you have adequate flow through your powerheads in your tank it won't cause major problems, but i would say you need a larger pump long term.

M1500 = 6000l/ph right? i think so, so 6000 x 2 = 12,000lph / 500lts (your tank volume) = 24 times turnover, a bit low, perhaps a smaller powerhead directed low behind the liverock, while the 2 seios point from the top rear corners to the diagonally opposite front corners should give you a good flow in the tank.

i would say increase. maybe add another two M1500s or two more M1100s, depending on what you want to keep. But that should sort you out. I think you would need to up the return to about 1800lph or 2000lph. then it should be sufficient

No, if you can rather keep it. If something happens to your return pump then you have a spare ;)
