about to build my sump, got ???'s

That's what head means.
There are calculator on they net that will figure it for you, some will even figure the lose for the fittings(90's 45's etc) but that is minimal

A 2" flows 1760gal/hr @ 36"

 

Yes, I am using bio balls in the sump I have now but remember quite a few years back we used to use rocks/gravel in the sumps and that being porous and coarse they give the bacteria a good place to colonize.

 

It will still grow a some bacteria, It would grow more with the water flowing through it, but the bacteria will colonize every surface in a tank where oxygen is available given time. That why an aquarium becomes more stable as time goes on

Yep seen that one before makes big mess don't it!
last time it happen to me(a cracked return pipe) it pump out about a hundred gallons but I have a tile floor with a floor drain so didn't do any damage

When I rehabed my basement I put in ceramic and drains in every room, I also live on the river so this helps alot.

Ive had the hose pop off my canister before but if it went on the sump per where O/F box is and sump id maybe have 10g on the floor.
Ive been very happy with not doing any DIY less the 1-2 split into the sump itself from the O/F box. I am making my own O/F box with specimen containers per instructions on my site.

 

you are in georgia, you guys dont have basements do you?

before my drains I had a water pump and just made sure before a storm I had my channels down and it drained away that way but those PIG mats get expensive.

 

When we pour the floor for my fish room the guy who did the slab work was so worried about the drain ending up to high that he set them in little depression maybe a half inch low. Them finished little bowls around them. They look good till the tile man trying to cut the tile in around them. He evidently had never seen a floor drain before and muck up the job to the point that it couldn't be saved and end up being a do over.
