I've been running a 20 gal reef with a HoB filter for about 6-7 months now. The fish/corals have all been healthy, but I've been having a hard time keeping the algae under control as it seems the filter can't quite keep up with the nutrient input. Enter DIY sump...
I built the sump, got a skimmer, and got the pump and overflow basically in synch, but for whatever reason as soon as I started running the complete system my fish were immediately in shock, and looked like they were going to die. I've tried twice and had the same, almost instantaneous result; unfortunately it looks like the wrasse isn't going the hang on (we'll see).
I'm curious if others have run into a similar problem getting an after-the-fact sump up and running.
Thanks
