Broke down my 300 and I still have these 2 skimmers available. I had it run in-line with my return so I don't have any pumps available for these skimmers. I also added an airstone to each skimmer to increase foam production.
I had it running in sump but you can also run it out of sump. Comes with gate valve to adjust the height of the water in the skimmer.
I have 2 skimmers available. 80 each or 160 for both.
Text would be the best way to contact me.
Thanks,
Cedric
