Red Sea needs to re-design the plumbing and sump for the Reefer 750. I wish I got paid for the hours of time wasted messing with that terrible gate valve. This could be a trivial subject but if you buy any substantially sized protein skimmer, it won't fit into the first chamber of the sump, so you have to run it in the 3rd chamber (what I see as the refugium). The sump is poorly partitioned with a removable refugium wall so it would be difficult to use either chamber as an actual refugium without all of the plant matter and other waste particulates getting into your bubble trap or flowing into the skimmer chamber. I think the idea is to run the refugium before the skimmer but from everything I've read that's not a great idea. Maybe I am being picky, but as a new reefer, I tend to follow what the majority are doing as best practice. Another fun thing that Red Sea needs to change is how they package the tanks, you can't just build the stand and then have your friends come over and help you move the tank, you have to unfortunately discover that some of the stand pieces are under the tank that any (2) people can't reasonably lift (I recommend 4 for safety). So you have to get help moving the tank twice over stupid packaging order. I love my tank and am really enthusiastic to the hobby but Red Sea needs to take feedback and continuously improve their products or others will surpass them. Hopefully enough of our complaints on forums like this will help.
P.S. The information shared on this thread was helpful, I am also switching to a spears gate as well as adding a ball valve before the gate so I can simply shut off the drain when needed without messing with the gate setting.
