so im selling my ae tech protein skimmer with extras. skimmer works great!!! rated for 100-400 gallons.i got it from a guy who had gotten out of the hobby and already had my system up and running so i really didnt have enough room for it. ran it for about 3 months but needed something a little smaller that i could fit in my sump. im selling it with the iwaki pump that i got with it plus a mag 950 pump and am extra collection tube that connects to the collection cup. im offering both pumps cause some people like the pump to be in the sump and others dont so now you can have it whatever way you want it.i ran it on both pumps and got the same results from both of them. any questions just pm me or even text me ( 248 )420-6486 almost forgot...skimmer size is 13'x10'x26'
