Of most interest to you (given your high N/P ratio) is that these bacteria are denitrifiers. They can remove a substantial amount of NO3 in this way, even after other bacteria eventually stop assimilating NO3 due to a lack of PO4.
And that's exactly why I'm still on the fence. I have decent NO3 and fairly low PO4. I'm afraid if I use it and the NO3 tanks I'll get mad nasty algae since I still have PO4. With that said though, NO3 is cheap to dose which is why I like the idea.
Overflow box.
I've had some issues with algae clogging the baffles on occasion. I just check and clean them semi frequently.
It's a glass tank. I already broke one of the 125s... Drilling glass is something my wife and I have messed around with a couple of times for other projects. We have never been successful - it cracked each time. I've used overflow boxes on all of my reef tanks on the past and haven't had any problems so it's basically the monsters I know vs, as @Mibu said, the scary one.
I had an over flow box on my last aquarium. It was a crappy setup. Only issue is as you stated earlier, keeping the grate clean. Other wise, never failed me when things turned off or back on. Many power outages in White Sands. I love the look of the setup.
Yeah. I'm guessing they were soaked in saltwater for curing.
