what pump to replace a diablo dc-3500S? from my research a varios 2s would be the choice which is backed up by a call to brs and the "pros" research, while coralvue says a varios 4s or bubbleblaster 3000 is the replacement and well the marine depot "pro" needs to find another day job was of no help just said "if coralvue recommended the 4s go with the 4s" he didnt even do any research while i was on the phone ( note: i personally will not be using marine depot for stuff at this point if i can help it). so would you say a varios-2s is the pump i need to replace the old diablo dc 3500s pump?
