Reef Octopus 5000SSS

Hi

The pump of my skimmer is breaking.

I never change the pump but the model i have on my skimmer is Bubble Blaster HY-3000S and i suppose to have Bubble Blaster HY-5000S.

I need to buy a new pump fast but i suppose to buy Bubble blaster HT-5000S.

I need to know in the Bubble Blaster HT-5000S fit on the bracket i have on my Reef Octopus 5000SSS because i have the HT-3000S pump.

Thank's for help !
