Been a while - getting another reef tank up, a few ?'s

Sup guys, been a while.

I've got a 40b sitting in the basement and I think I'm ready to get started setting things up.

I want to drill this tank using the complete in and out system from glass-holes.com, and am wondering what size pump I should get? At one point I had done all the math (headloss calcs) but I have lost all of that info. Anyone point me towards a headloss calc link?

I'm just going to start out with fish for the moment, but I do have a nice skimmer (SRO 1000SS) and would like to get some LPS/softies at some point.

Any help is appreciated.

I didn't run through your head loss calculations, but 750gph seems like a lot for a 40breeder.

Folks here seem to recommend about 5-10x display volume to turnover through the sump, so a pump somewhere around 200-400gph after head loss.

If you already have the pump, and your overflow can handle it, it could be fine. I might just worry about it being loud. You can valve down the pressure side of the pump as well.

Gotcha. The Quietone 1200 would give me 220gph after head loss.

Any idea how to do the calculation by listing the GPH of the pump? I want to calculate a pump that isn't listed on the drop down list. (Danner mag drive) 500gph?

I used a Mag 9.5 on my 50 from an under stand sump. Delivered good flow for stony coral.

There, that's more like it.

HTH

but I know it doesn't. so add this: if you are spending money I'd look for something newer. the mag drive line gets loads of comments that they run louder and hotter than they aught to.

If you already own it, well, sorry.

Simply look at the flow chart published for that pump..

I'd avoid mag drive pumps personally... old/loud/hot,etc...

Suggestions for pumps then?

I've only ever had Danners, and Quietone pumps...

Quiet one 3000 pump will give me 500gph after head loss... is that too much for a 40 breeder?

Guess I can always T off and use ball valve to go back to the sump if needed.

Yes you can. You can also valve down the pump.

You mean put a ball/gate valve on the main return line?

I thought that was bad for the pumps?

You can valve down the pressure (output) side of centrifugal pumps.

It doesn't hurt them. It's no different from adding head pressure. It reduces the output, and they actually use a few less watts.
