Can I get away with an internal pump?

[SoloSK71]

10x turnover through the sump is recommended.

At 12' (4m) this pump won't be able to do much more than 900g or so an hour.

The Syncra HF 16.0, Reef Octopus Water Blaster 16000 or Deepwater Aquatics BLDC15 can provide that kind of flow at that height.

Yeah, I was looking at the Deepwater Aquatics one as well, seems to be the most efficient for that size.

I use a waveline and is quiet but makes a little noise, I heard that ecotech and vertex pumps are super quiet...

L1 won't be able to pump that head height.

You sure you're not thinking of the M1? According to this link the L1 will do 8-900 gph at 12' which is a good number for your tank size.

Another thing to consider, you could install your sump on a platform and raise it off the floor 4-5 feet and still have lots of room to play in it (assuming 8' ceilings) which may be the difference between using an internal and external. Just make sure you design it so that you still have easy access to the sump.

The Sedra 20000 is an excellent pump for high head pressure, much better than the Mag pumps (which I have also tried). I have had one in my basement sump, pumping upstairs to my main display running for 6+ years with no problems.

They put it on sale sometimes.

It actually runs two tanks (another one downstairs) as well as a couple reactors, all off a set of Ts in the sump. And always starts reliably after a power outage (unlike the mags).

You sure? 1100 gph is around 5x and that's bare minimum. It's really on the edge. I don't think it would work.

Yes, it's on a 40" stand already.

Looks decent, a little power hungry though.

I usually shoot for 4-5x, more than that is fine but it might be a little bit of old school thinking. I don't know if it really matters, if water goes through the sump twice as fast but is only skimmed or goes through reactors half as much each time, it's the same end result either way. Higher turnover does put more through your filter socks though.

Some of the newer 'systems' suggest higher sump turnover, Triton, Zeovit, not sure why.

Bummer it's already on a stand!

I'd be happy with 1100 gph on your tank. I wouldn't call it bare minimum at all. Are you doing a full siphon drain like Herbie or Bean? If so, you don't want to tee the pump off for anything else anyway.

It will be a bean setup
