Sequence Reeflo 2500 GPH feedback

[jaydub74]

I'm setting up a 78 gallon tank complete with closed loop - is this to much pump 4' of head pressure - pump to be located directly below the tank? any feedback would be great.

no one has experience with this pump?

It all depends on how much flow you like.I is going to be like a big whril pool in your tank.I run that same pump for a return on my 210.

Have you tried asking in the equipment forum? You might get more help there. Sorry I cant be of more service, I've never used one.

My understanding is that I should be turning over the water 30 times per hour... 78 gallons x 30 times turn over = 2340 gallons per hour. That would put this pump in the correct range I think.

Is my thinking correct or should I pull back a little and purchase something smaller.

thanks to all those who have replied so far.

I think that would be great for a closed loop on that tank. BTW, there is no head pressure on the pump in a closed loop.

 

[Kannin]

Remember... elbows & T's in your pipes will increase head pressure and so will reductions in pipe size... like if you have 3/4 lock line on your returns. The Snapper is a flow rated pump which is affected more from these things than a pressure rated pump. If you are really worried, put a ball valve on your outlet incase you need to tone it down a hair... Also... what gph are you getting from your return pump?

 

[jaydub74]

I guess I'm a little confussed... LobsterOfJustice says there is no head pressure on a closed loop and Kannin says there is?

I have not purchased a return pump either but I was think about getting something is the 500 gph range unless its possible to use one pump to both return water from my sump and run a skimmer.
Is that possible?

Is the sequence the best solution or would you recomend something different. I just want something that is quiet and energy efficient.

thanks again

i should not that I plan on keeping sps and maybe some lps later down the road. Please take that into consideration.'

thanks

There is not head pressure in the traditional sense, but there will still be some backpressure from elbows and other fittings. That should be pretty neglegible though.

You can use one pump as a return and for a skimmer, but it's better not to. That way if you need to adjust the return flow your not messing with the skimmer water level and vice versa.

LOJ is right, there is no head pressure on a closed loop. A closed loop is simply a pump plumbed directly to the tank. That is, water is simply sucked out of the tank and pumped back in in a closed system/loop (no contact with air). An open system involves water flowing down an overflow, into a sump, and then being pumped back up to the tank.

You want that 30x+ flow in your tank using internal power heads and/or closed loop. Running that much water through a sump is a total headache. You only need about 2-5X tank volume actually running through the sump.

 

[jaydub74]

What pumps are guys using for your closed loops? would you recomend them for my tank?

Are you saying I could get away with a 300 gph sump return pump.

Is the fact that I want to go BB going to effect the pump i pick?

 

[SDguy]

BB just means you can have lots of flow and not worry about blowing sand around.

I use a hammerhead on my CL.

I run about 500gph through my sump (115g tank).
