Needing help to find the right size water pump asap

[shewolfgeo]

My external pump on my display unit isn't doing well. I think it'll kick the bucket soon. Water flow is slowing down with it...

I don't know what it is, nothing listed on it for me to tell.

So what would be good for me to get to replace this old unit. The display is about 100-120 gallons. I was looking at blueline, but can't find anything telling me what model is good for so many gallons..

Help me out.

Thank you.

For my 100's and above I have been using Supreme MagDrives. I use the 7 and the 9.5 most of the time and have a 250 and 5 for emergency. I was thinking of using the Little Giants but right now I don't want to hard plumb anything. Based on my observations, they seem to hold up well. Have a friend with 5 of them on saltwater and FW systems running for 5 years that I know of, they may have been running longer than that.

so glad you mentioned the Supreme MagDrives.. Just looked it up on ebay and the 9.5 is the exact one I have on my unit.. Think I'll stay with that one and go buy one now.

Thank you much!!

YW. Have you tried replacing the impeller? Sometimes they wear out. Easy to replace. My MagDrives have been running about 3-4 years and honestly haven't checked on the outflow.

I didn't think of that. I don't know how old this one is. I went ahead and order one. I'll check this one out and see if the impeller needs to be replaced. I can use it as a backup then.
