thanks for the advice in the past i have come to the conclusion that the Red Sea Prism Skimmer will be better than the Biostar floater,Seaclone and the Aquamedic 750 turbo, the last one being alittle on the large side when i went to the local shop!!. I , with the help of the shop assistant hung the prizm onto the back of the rio 240 to see when i elongate the rear left hand cut out to the size of the return tray of the prizm it will sit below the rebate which allows the rear flap to close completely( is that clear lol). I realise that i still have to cut a small notch out for the water out pipe therefor i was hoping that maybe someone out there has a prizm on a rio tank and could do a little measuring for me as the shop didnot have a tape measure and was selling the skimmer fo £125 which i think is a little on the expensive side
