What return pump for 150 wide

I am in the process of purchasing a 150 wide tank in Texas.  It will have a single overflow, but the drain will be upgraded to a 1-1/2" bulkhead.

Im running a dart on mine. Oceans motion 4 way with 4 returns.

Where do you want your flow coming from, return pump or in tank powerheads.  Its far less costly to use a moderate return mag 9 or eheim 1260,1262 and run koralia, tunze, votechs etc in tank for flow.  Running a snapper ro dart on a OM 4 way is also a good alternative, are there any returns drilled in the tank or do you want to take them over the top?
Another great return pump is the laguna line (same as red dragon) you could use a 1500 or 2000 and get great return rates and low electricity usage.
What are you doing for a sump? and do you want an internal or external return pump?

i have to agree with dion and go with the dart. the mag pumps use a lot of electricity for their size and add a lot of heat to the tank. the reeflo dart however is very efficient, well most efficient in the industry, and it adds very little heat, and is super quiet. it also uses less electricity when you throttle it back and put a ball valve on it. it has the power to run your whole tank with one pump, or a skimmer, ect, but uses less electricity. seems like a no brainer to me. you can find them used on reef central all the time, or on ebay for great prices.

the dart would definitely work perfect for a return pump. you can throttle up or down depending on how much flow you need, and unlike other pumps, when you throttle down, it uses less electricity.

i am going to use a reeflo barracuda for my return pump. should work great. just like the dart, but bigger.

I like Sequence pumps, but the flow you need from the sump to the tank is much less than what a Dart can produce for a 150 gallon tank. This whole thread is crazy talk, especially without knowing what kind of sump Lorraine is going to use. If you have a big sump, you can run a big pump if you want.

In my own experience of having a massive, single return pump, I would do it different for sure.

Why put a Dart on a tank with overflows that can't handle it full-throttle? It's not the drain that causes the problem with a lot of flow, it's usually limited by the overflow teeth or weir length. Seems silly to me, honestly. A Mag 9.5 or 12 would be reliable, somewhat quiet, cheap, etc. Use a Korallia or Stream powerhead with a mag pump or an ehiem and forget the giant return pumps. A mag pump doesn't contribute a considerable amount of heat to a 150 gallon tank, really.

If you want a Sequence, then get a Snapper. It uses much less power and produces less flow.

#1 consideration for any tank is flow. Corey is right about the lack of knowledge of what size sump she is using. However I highly doubt that she would be using a 20g sump on a 150. My 150 has a 55g sump. It has 1 overflow with 2 drains and it handles the flow from a dart with out even blinking. My 125 had the dual overflows and I did modify the teeth. (cut them out and screened them) Worked like a charm.

for all the nay sayers, i can think of one good reason he may want to go with a dart on the tank: THE FUTURE. he may want to run a closed loop, may want to run a skimmer, may want to feed a uv sterilizer, may want to feed a carbon reactor, ect, ect. the price difference isn't that much. the power difference isn't that much. less than 50w and well on marine depot there is no difference in price...lol. the snapper is 1900gph at 4' of head, so dual 1" overflows would do about 1500gph and he would have a measly 400gph to run anything else he decided to run. if he went with the dart, it would be 3035gph at 4' of head, and he could feed a large skimmer, uv sterilizer, and a closed loop. there are lots of options to weigh out here, but calling the thread "crazy talk" is pushing it, if he wont ever need the extra flow, go for the snapper, if, "if" theres ever a slight chance that he will use the extra flow, he should bite the bullet of $0 dollars and get the dart.

I like to go with a return pump that flows only 3 - 5 X tank volume per hour; IMO more than that and your skimmer and / or refugium lose "efficiency" because a high gph through your sump means alot of water passes through the sump without going through the skimmer...
