After i thought about it. Not sure the baffles in the 75 refugium need to be watertight. The baffles are just for a bubble trap, and to make sure nothing gets into the pump. So a pinhole leak makes no difference. So, tested sump, fuge, and pump today. <a href="http://s1028.photobucket.com/user/acer327/media/Mobile%20Uploads/2016-08/IMG_20160828_162052993_zpsmwrzbyfz.jpg.html" target="_blank"><img src="http://i1028.photobucket.com/albums/y342/acer327/Mobile%20Uploads/2016-08/IMG_20160828_162052993_zpsmwrzbyfz.jpg" border="0" alt=" photo IMG_20160828_162052993_zpsmwrzbyfz.jpg"/></a>
Yeah,. It worked, only had one issue. The bulkhead between the 75 fuge and the pump leaked. Arrrrggg.... , but no biggie, switched out the one above it. I was very surprized how quiet the reefflow pump was. It was the one i got from Frank. I would think the regular Barracuda will be even quieter.
