Any reccomendations on a 2400gph pump? I know mag drive makes one that is rated at that. I am happy with my mag drive now, it is quiet and seems to work very well. I would like one that is economically priced and is all around a good quiet pump.

I use the mag drive 2400 as my return pump. It seems a little noisy to me but not real bad. The reason I went with a mag is because I use it submerged. There are probably in line pumps that aren't as loud.

This would be overkill on your new tank. Why not get two SilentSeas instead?

Other than heat build-up what is the advantage of a external over a submersible? I have plans to use a rubbermaid 40g container as my sump, what would you use? A external or submersible in this case?

A tiny shy of 2400g/h, but a top notch pump, Iwaki 100 RLT.

external pumps are stronger and usually last longer. They run cooler if they use a fan. Most do except sst800 ect. I prefer external no matter which kind you get. iwaki, dolphin ect.. Just matters if your tank heats easy. If not I would get dolphin sst. Iwaki 100 is alot bigger than mag 2400. This is 2400 at 0. What do they cost? For the $$ they maybe good and I wouldn't like to bulkhead a rubbermaid.Others may not ever had a prob but they seem pretty thin and just something I wouldn't like to do. I might stick with the mag. Even if i prefer the inline pump.

Is it just me or do these strangely resemble SEN pumps?

Thats the delima I am in. The rubbermaid is the best all around sump I can ask for. It meets my first requirement, cheap [img]/ubb/lol.gif[/img] but not cheaply built. I know the mag is only rated 2400 @ 0 and I will be pushing maybe 3', so I expect a drop to 1800gph or so. I really would like to find a stronger submersible pump to get back to 2400 at 3'. I can use a bulkhead on a rubbermaid by using a flat steel washer on the outside and a plastic flat washer on the inside with silicone squirted all around as it is tightened. I have to make the plastic, usually out of acrylic or plexi. This stiffens it up very well as long as my bulkhead is threaded long enough to support the extra 1/4" of width. So, with that Ameri-engineer soultion I may be up to a supported external pump?

The Iwaki is rated at 2000g/h at a 4' head. A Japanese model is not cheap, but this is one of the most dependable and quiet pumps you can buy.

Why do you need so much power? what size tank? or is the sump gonna be far away? you can use 2 mags. but if you want to drill and bulkhead like you said Iwaki or GRI wouls be good pumps but cost$$ Iwaki @ $308 gri @ $280 Mag 2400 @ $120x2 =$240 but not pressure rated mag. If you truly need the larger pump go external. can you double up the rubbermaid to make the sump stroger? They are flimsy. I just don't understand saving $$ on a sump and spending $$$$$ on a pump? a 40g used acylic tank would be better even a wetdry or glass tank and have it drilled IMO

Ironreef, I will have (2) 1-1/2" id bulkheads on a up and coming new tank. Each bulkhead supposivly can easily handle 1200gph for a total of 2400gph. This will be on a custom 125g tank. I want to utilize as much of this as I can having this be the primary circulation in the tank. I want to keep the ph's to a minium This brings me to my next question, how is the best way to create a circulation in the tank with this return? I do not want sea swirls becasue the mount to the tank sides. My hood will be for the most part completely enclosed. I had thought about these http://www.premiumaquatics.com/Merch...ode=Wavemaking but I dont know much about them.
As far as the rubbermaid, I can get one at wal-mart for 9.00 that will fit under my tank perfectly. I am also keeping my eyes open for a used 40g long tank, but most of what I am finding are high priced. Now a new acrylic tank would cost me much more I assume, I havent a dealer of them locally and havent found any reansonalbe ones online yet. I am trying to save money on the sump which is why I am researching them now. Why would I need (2)2400 mag's? I know they are head rated at 2000gph @3' http://www.petwarehouse.com/webstore...?OpenDocument. I could get (2) mags as you said that are head rated at 1200ish @3' and still be less expensive. This tank will be sitting in my living room and I want it to be as quiet as possible without breaking the bank thanks for the input!

you may not need to mags.I didn't know what you wee doing and was thinking you needed a high powered pressure pump. I would get a mag and keep it in sump it will be quieter and sometimes they leak so it wouldn't hurt in sump.The mag will give more than 10x turnover which is good. easy fix if they leak just put tape on the o ring. The return I never seen. You may try one and see? may be good.Or ask more about them

Your right that may suffice. I cna supplement circulation with a few good power heads. I am shooting for 20x turn over rate on the tank. Thanks for your input

Since your setting up a new tank i would try to do it with as little powerheads. IMO they give good current but random type are better. even with a wave maker if you have a seaswirl or that other thing maybe better cuz they look better and its less in not easier maintance. You can still use powerheads but I would try to do it with as little as possible. seaswirls not an option for you but you can have the big mag for a return to a flex nozzel and try the other return on a smaller pump. You still may need a powerhead or 2 on a timer but IMO its looks better if you can do it with nozzels and other types.

Ironreef, do you know anything about these? http://www.premiumaquatics.com/Merch...ode=Wavemaking
I agree, I want as few if any ph's in the tank. I will have the returns to a flex nozzle that I can fan and adjust. Do you know of any way I can return the 2000gph into something that ocilates? If I have to use a powerhead or 2 I can control the on/off cycle with the PLC I use now and will be using to control the lights.

I don't use an PH's in my 130 at all. My Iwaki is T'd to 2 returns, both come up in the overflow. At the top of each return they are then Y'd with Kent flex-pipe. This gives me a total of 4 returns to direct anywhere I want. With a turnover rate of close to 15x/hr there is no need for PH's. One thing to keep in mind with a high turnover rate like this is that you need a good sized and designed sump. It is very tricky to keep micro-bubbels out of your tank pushing high flow in a small sump. My sump is a 30gal. and I have tossed around the idea of going 50-60gal. Actually if I were to move it to the basement where the pump and chiller sits a 75-100gal. would not be out of the question. Hell why not just flood the basement ang go that way[img]/ubb/lol.gif[/img]

Baja, If you had a pool then......... I will have a 40g sump, of course only 1/2 will contain water. I will have several bulkheads for over and under travel to keep bubble to 0 or a mininum. I like the Idea of teeing off the 2 returns into 4 total. I plan on check valving all lines with good pvc valves. This will be the secondard/primary saftey for power outages. I hope to turn the water over as much as possible. I wont be able to hit 20 just off of the return, but hey whats a few less. Its still good. Let us know if you go the pool route [img]/ubb/lol.gif[/img]

I"ll tell you I used to live in florida. I had an awsome pool with a glass block spa in the center. I have dreams about still living there and turing the pool area into a reef[img]/ubb/lol.gif[/img]You know how you always think of these things after the fact. Oh time to wake up and realize I'm back in lovely NJ[img]/ubb/frown.gif[/img]
Anyway here is a pic of my sump.
