This skimmer was given to me free over a year ago, but is missing some parts; I am wanting to know what all I need to purchase to get it up and running. It needs a good cleaning I know, but you can't beat free!
The pump is an Aquatrance 1000s Skimmer pump. Can be had on Amazon, from Coralvue, Saltwater Aquariums and a ton of others.
The silencer can be found at the same places, but is usually not a typically stocked item. I broke mine a while back on my 110 and made one from a large pill bottle and a some small diameter pex pipe. Just basically copied the design and watched for when one was in stock somewhere. Wish I had a pic of it, but you can easily DIY a silencer.
