Sea Apples - experiences/thoughts?

[Treebeard]

I am pushing the water about 11 feet up from the sump in my basement to the tank on the main floor, and I have the flow throttled back somewhat. I almost had a wreck on the weekend when I noticed the tank was on verge of overflowing. I need to find a gate valve rather than the crappy ball valve I am using to properly regulate the flow. I would like to get the flow up to around 450 gph.

No other powerheads. Before he settled in, the sea apple would climb up the side of the tank and park himself next to the Koralia 3 with no ill affects. They have a fairly hard exterior, and I cannot see how they could get caught up in a Koralia, like my seahare (rip) did.

how much piping do you have going through there?

Thanks for those specs, very helpful..
Is that all you have for water movement?
No other powerheads or anything with impellars?
