The noise level of the Mag 7 isn't that bad, honestly. I can't really tell that mine is running at all. The sound of the overflow is noisier than the return pump, honestly. I had an eheim pump at one point, and for the price I didn't feel like it was all that special. But, that's just my opinion. There are more people on the boards that have had better experiences than I with it. I just know that if I want durability and stability, I'll buy Mag Drives. If I want slightly less electrical consumption and slightly less heat in the water, I'll try a different pump.
Sounds like you have put thought into your system. Can't wait for more pictures. Keep it coming!
Agree with Seth here....Really comes down to what your willing to spend.....Eheim excellent pump, less heat and electric over Mags....I'd put my money any day on the Eheim as far as longevity over a Mag, but can I honestly justify the cost difference between the 2.....Not really......

Hi folks,
Rather than starting a new thread for each question I come up with or hijacking others' threads I figured I may as well start a 'build' thread (although the way this project has gone so far this one will be
plodding along slowly...)
Background: I've been keeping freshwater for decades (currently with a couple of african cichlid tanks). I decided late last year to finally give SW a try as well (it's always been a question of when, not if). I'd like it to be a 75g reef tank, ultimately. Here's what I've done/gotten so far:
Read a lot (Fenner's "Conscientious Marine Aquarist" cover-to-cover + plenty of online stuff + working my way through Borneman's "Aquarium Corals".)
Have the tank (75g reef ready).
RO/DI unit is on order. Any month now.
Skimmer should arrive later this week (Vertex Omega 150); perhaps a bit odd getting this piece of equipment at this stage, but I had hoped (in vain) to have it in time to ensure the stand I'm building is tall enough for it.
Finally,
- after much frustrating delay, got started on the stand yesterday. Worked on it some more today. It is structurally complete - now I just need to do the cosmetic stuff. Couldn't wait for the skimmer - long story, anyhow the clearance inside the stand is 25.75". The skimmer is supposed to be 21.75" so shouldn't be a problem there... whether that leaves me room for a neck cleaner I don't know (I could always cut a hole in the top of the stand to eek out another inch if that makes the difference).
This brings me to my first question in this thread... the return pump. The bulkhead restricts the overflow drain to 1" internal diameter. I'm planning to layout the sump so that the return pump, if possible, is directly beneath the return hole, so that the only bend is the 90 degree bend at the top of the return. The choke point in the return flow has a 1/2" internal diameter. How powerful a pump to get? I've always liked Eheim gear for the quietness and durability of the motors and don't mind the premium price for that - the question is whether a 1260 would be enough? too much? Head height will be a shade under 4', before factoring in the 90 degree bend.
I'll put some pics up as soon as there is anything worth showing...
Thanks, Paul.
Skimmer choice is excellent......As far as your plumbing....Is that standard 1/2"......Definitely need to open that 1/2" up that is so restrictive IMHO.....I'd opt for the 1260 or worse case the 1262 if you can find them.....Them pump can always be valved off to feed other equipment as well.....

IS the return bulkhead 1/2"? Most standard reef ready tanks that have a 1" drain bulkhead actually have a 3/4" return. I've never heard of a glass company restricting flow that much in a return pipe that has a corrosponding 1" drain. I don't know. Check it out to make absolutely sure your positive on the size of the return plumbing.
Eheims are great little hobby pumps. They are quiet and they don't transfer a whole lot of heat to the water (from what I have heard). However, I go by the rule of thumb that a pump gets as hot as the watts that it uses. So, a 70w pump is like having a 70w heater turned on all the time. Eheims use slightly less watts than Mag Drives (compare 68w of the eheim to a 70w Mag 7) and then take the cost of the Eheim: $129.99 vs. the Mag drive 7: $84.99 the difference is very slight and maybe you will get the difference back over the course of the next ten to 15 years.
Mag drive pumps (for you the Mag 7 would work wonderfully) are a good choice for hobby pumps because they are durable, you can easily buy spare parts and they usually last for a decade with the same impeller. Put another impeller in it and it will last for another ten years. But, ultimately the pump decision is up to you.
If you want to also look into another brand, try Sicce pumps... those are top quality hobby pumps. Also, if you have the money, Red Dragon is perhaps about as good as they come.
Lets start seeing some pics of your build progress!
Red Dragon's.....Yeah as good as they come......Another option I'd consider honestly before a Mag would be a WaterBlaster pump......

Thanks for the reply!
I checked and the exterior diameter of the return bulkhead is 3/4", ******** diameter about 5/8". The 1/2" restriction I'm referring to is an articulated plastic thing that attaches to the elbow at the top to route the return water past the overflow back into the tank. I suppose I can easily replace that bit with something diy. Come to think of it maybe I should look into replacing the bulkheads as well? This is Deep Blue and since picking up the tank (in a post-Xmas sale) I've gathered that the supplied bulkheads are not very good. The holes for the overflow and return are 2" and 1.5" respectively. Can I find better (and larger ******** diameter) bulkheads for those hole sizes?
As for pics, not much to show yet but here is the basic 'wood box'. Still need to cut some holes for the plumbing, electrical & ventilation, then time to spruce it up, (finishing ply, moldings, doors, stain, etc.) So far I'm please with how level and square it turned out, and how strong it looks & feels. The vertical 2x4s protude 1/2" below the rest of it. That gives me only 4 shim points to worry about on my uneven basement floor, but it's also low enough that if there does turn out to be an issue with unwanted flexing in the top front I can slap in a center post and shim the support to the floor easily. I'd really rather not have a center post but it's always good to have a plan B - and if need be I could even make a removable one.
On the question of rigidity obviously the front span is the key area of concern with no center post; for a preliminary assessment of how well the design worked out I did a simple test using a length of wood cut precisely to fit vertically in the front, so that it just fits between the upper and lower plywood fascia. I then parked my 185 lb self centered on the front edge of the stand to see if the piece of wood would still fit in. Almost. As best as I can measure there is about 1mm of flex in the front center with 185 lbs concentrated on it. Considering the weight of an 800 lb full aquarium would be distributed evenly around the 4 edges I'm hoping even that bit of flex won't occur, but I'll make sure to check when I get around to doing a test fill.
Looks good......Shouldn't need a center brace on a 75.....It's a 4' span as Seth suggested.....As far as shimming shouldn't be an issue at all on the basement floor.....If you have to shim I'd use solid lumber to shim if you know what I mean instead of shimming just the end or edge......

That is great to hear regarding the stand, very reassuring, thank you!
The kit that came with the tank does appear to be a durso style setup; the only thing I believe that was not included would be the piece of airline to stick in the little hole... I'll look into the larger 'locline', thanks.
Re the return pump, I hear Red Dragon's are fantastic, but I think they're just a little over the top price-wise for me. How is the noise level of the Mag7 vs the Eheim 1260?
For lighting, actually I got that as well, sort of... I went a little nuts at that post-Xmas sale and picked up a 48" Deep Blue SolarFlare DX at $100 off... 48 3W LEDs, looked great in the store. Pretty quiet, seem to run cool enough, and very bright. Not too many Customer reviews out for these on the web and those that I've seen have been mixed - some good, some bad, but none based on any real experience with them from what I can tell... oh well, if they don't end up working well for corals they'll become the lighting upgrade I've always wanted for my 28" tall Malawi tank; they are very bright and will reach to the bottom of that quite well, though I might have to diffuse the light a bit to illuminate the whole 6' length of that tank.
Re what I plan to keep that's still a bit up in the air. I do want to keep corals, possibly including sps, but a flame angel is also high on my wish list. I know Centropyge can be risky with corals, I haven't decided on that yet. A royal gramma is a definite candidate though. Not very original choices I suppose, but then this is all new to me so nothing is boring! I figure there's still plenty of time to decide on other fish though, as well as inverts. I'll start focussing more on coral selection & placement once the tank's been running for some time. The goal of this tank is balanced diversity (corals, fish & inverts) - not seeing how many fish I can stuff into it.
Could cost you a kidney........Love the flame angels.....The angels are hit or miss IMO.....
